II.   Safety Concerns Unveiled

Laser engraving techniques open doors for tremendous innovation and craftsmanship, but they come with inherent risks. Knowing these dangers is paramount for a safe and sound experience, so let’s break down some key areas of concern and be mindful of the practical ways to deal with them effectively.

A. The Invisible Risks: Eye and Skin Safety

When using laser engraving machine, know that you’re not just dealing with the machine but also handling the technical and high-voltage system. With them in your space, there are some potential dangers lurking around, especially on your skin and eyes. That laser beam you see may look harmless, but it packs a punch without the care.

Direct exposure to these highly concentrated laser beams can mess up your eyesight or may leave nasty burns on your skin. These rays entering the eye in this way can cause permanent damage to your retina, resulting in a blind spot – or worse still, damage to the optic nerve. Long-term exposure to 1µm radiation can also cause cataracts on the eye’s cornea.

So, what’s the solution? It’s safety eyewear. It’s essential to follow safety guidelines and best practices and get some good quality eye goggles to shield your most sensitive part from those radiations. And don’t forget to dress up in appropriate gear to cover your skin. Trust us, it’s better to stay at a distance from these rays and equip appropriately to avoid those painful burns.

B. The Air We Breathe: Ventilation and Health

Another often-overlooked aspect of working with laser engraving machines is assessing the quality of air in your workspace. The working of laser technology is a high-powered task that may cause many chemical reactions to happen, releasing elements present in the alloy into the surrounding air.

Now, these poisonous fumes, vapors, particles, and toxic metallic extractions from the substrates can make your breathing unbearable and, in many cases, can pose some serious health issues.

ABS, PVC, and fiberglass are the three most common materials on the “Forbidden List,” so be careful when navigating these materials.

In order to combat this issue, adequate ventilation is all you need. Make sure your working area has good natural airflow or either way, install mechanical systems in place.

Installing air filtration units to capture and remove airborne contaminants is another effective way to deal with this aspect. Additionally, wearing respiratory protection, such as masks or respirators, can provide an added layer of defense against inhaling harmful particles and fumes.

C. Fire Hazards: Prevention and Preparedness

Laser marking, cutting, and heating are all thermal processes, so they can cause a flame at the surface where the laser is being applied, making the fire hazard a legitimate concern.

Certain materials used in the processes might ignite, especially when you’re processing flammable materials such as wood and plastics. So, these materials can quickly escalate into dangerous fires without careful precautions.

But don’t be scared! All our laser equipment has a very decent setup that will make you avoid fire hazards in most cases.

Still, to mitigate its harmfulness, implementing fire safety protocols, such as having fire extinguishers readily available and knowing how to use them, is crucial for prompt response in the event of a fire emergency.

III.   A Seller’s Guide to Safe Engraving Practices

A. Selecting Safety Gear: Beyond the Basics

When it comes to protecting yourself from laser beam radiations, don’t just settle for any safety gear, but rather invest in a high-quality one that can truly keep you safe. Find eyewear that’s specially designed for laser work and that can better shield your eyes from the wavelengths these laser engraving machines emit.

Additionally, you can go for a face shield for that added layer of protection, especially when you’re working around materials like brass that produce flying debris.

As for your skin, it’s sensible to reach for flame-resistant clothing made from durable materials like leather or cotton.

Also, Gloves can act like your good friend in protecting your hands from potential cuts and burns. Be mindful that it snugly fits in, simultaneously allowing for dexterity in carrying out the laser tasks with ease.

B. Understanding Your Laser Engraver’s Safety Features

When shopping for laser engraving machines, it’s wise to keep your eye on the built-in safety features such as emergency stop buttons, interlock systems, and protective enclosures.

The emergency stop button is a rapid response mechanism that prevents severity by cutting off the power source to the machine system or other components.

Interlock systems offer a safe operating practice that prevents the machine from working unless the enclosures are securely closed, thus minimizing the risk of accidental exposures.

Protective enclosures provide a physical barrier between the machine processes and the operator, thus creating a shield from direct radiation and the dispersion of fumes, smoke, or debris generated during the engraving.

ComMarker is proud to offer all these features in its laser systems so that there is no risk of accidents and injuries when shutting down the machine or preventing operation if certain safety criteria aren’t met.

Moreover, check whether or not your suppliers meet all the safety standards and compliance regulations set by the Occupational Safety and Health Administration (OSHA). We at ComMarker ensure that our laser engravers meet rigorous safety requirements and have undergone thorough testing to guarantee their reliability.

C. Maintenance as a Safety Standard

When the maintenance part of the laser systems is discussed, it’s not just restricted to cleaning the debris out of the way but also involves the critical aspect of safety. By that, we mean conducting scheduled inspections of the laser tube, mirror, and power levels so they may operate safely without ruining the overall engraving results.

What’s better than keeping a clutter-free workspace so you can easily reach for your tools and materials? And don’t forget to check for your power supply to avoid power outages.

Those involved in the process must also ensure the area airflow systems are in good working order and that the fume extractors installed correctly extract fumes with dangerous chemicals from the air. This way, the worker is not exposed to nearly as many heavy metals and toxins.

All in all, following manufacturer guidelines for maintenance tasks such as calibration and tube replacement, are all there to protect you!

IV. Empowering Users Through Education and Best Practices

A. Training for Safety: A Non-Negotiable Investment

While you push the creative potentials of laser engraving machines and play around with varying parameters, ComMarker suggests you prioritize safety simultaneously. This comes down to the training sessions and a deep understanding of the safety protocols and emergency procedures.

Refer to our product manual, look for our website tutorials, and read our blogs; these serve as a solid foundation of fundamental skill sets to gain a revenue impact immediately. Whether with our fiber laser engraver, MOPA Fiber laser, or Diode laser engraver system, our laser marking machines ensure you maintain the dynamic balance where innovation thrives without compromising your well-being or the workplace’s integrity.

By embracing safety as an integral part of the creative process, you can unlock limitless possibilities while safeguarding against potential risks. With a steadfast commitment to both creativity and safety, ComMarker laser engraving machines become a transformative tool for growth, empowerment, and success.

B. Establishing a Culture of Safety

Now that laser technology has emerged from professional rooms and has become more of a thing to be used by hobbyists, artisans, and small private enterprises, the burden of responsibility for safety has shifted from experts to the individual user, often without the benefit of appropriate or adequate resources.

What remains, regardless of the working area, application, or system in use, is the constant goal of establishing and maintaining a laser-safe environment for the user and the surroundings at all times. This should be the goal of all who are involved with the sale, purchase, application, and management of all laser systems–under all circumstances.

Laser safety is EVERYONE’S concern! A laser is as safe or as hazardous as the user–and that user’s knowledge and skill are the basis of everything.  

So, beyond mere equipment and training, fostering a safety culture in the workplace becomes imperative. Open communication channels should be promoted so employees feel comfortable sharing safety concerns, reporting incidents, and cooperating with best practices. This is more of a proactive approach to hazard identification and mitigation.

V. Making an Informed Purchase: Safety Considerations

What makes a laser engraver a “Safe purchase” incorporates a combination of advanced features and meticulous design considerations for the well-being of both the operator and the bystanders.

If you’re eyeing a laser engraver, it’s indeed a smart move, but look for safety first. Here’s the lowdown on what to look for before you slap down your hard-earned cash

1. Enclosures and Interlocks:

It’s like a fortress of your laser engraving machine, so make sure it’s fully enclosed with an interlocks system that automatically stops the laser when somebody tries to open it mid-operation.  This prevents exposure to laser radiation or other possible injuries.

ComMarker offers a dedicated laser engraver enclosure to keep all the laser beams confined, ultimately protecting you and the surroundings from major uncertainties.

• Safety Certifications:

Look for trustworthy certification labels on laser engraving products, such as the FDA, CU, and UL set forth by the International Electrotechnical Commission (IEC). It’s like a seal of approval that guarantees the laser machine complies with the safety standards.

• User Interface and Control:

Because of the product’s technical nature, the laser machine with clear labeling, safety warnings, and ergonomic design contributes to the product’s appeal and ultimately signals safe and smooth operation. Therefore, before you look for a machine, ensure it’s user-friendly to instill user confidence and promote a positive experience.

• Emergency Stop Button

Look for the machine’s emergency stop button, as it’s a lifesaver in case of any mishap. A laser machine with an easily accessible emergency button is more likely to protect you by immediately halting the machine’s operations in case you find a hazardous incident or in case of an emergency.

• Safety Documentation

Nobody wishes to get into accidents, Right? So, make sure you get your hands on the product manual that dictates clear safety protocols and comprehensive training materials so you know the ropes before you dive in.

• Service and Support

While navigating the technicality of the machine, it’s often the case that things go south, and they inevitably do, so you’ll surely need a lifeline. Here comes an ultimate need to reach for seller customer support service to keep the laser machine doing what it’s good at.

ComMarker offers before- and after-sale support to ensure your machine stays in top-notch shape, minimizing downtime and maximizing productivity.

As the user is accustomed to Lightburn software with all of his lasers, he will utilize it in this video as well.

Although the laser came with small metal sheets for testing purposes, he decides to use them as backing to conduct a material test engrave. This precautionary measure helps safeguard the work area in case of excessive heat or penetration through the metal. He recommends implementing this practice for every material to be engraved, as it streamlines the process and reduces guesswork.

For instance, he demonstrates engraving on a simple stainless steel card. The manual provides settings that can alter the color of the engraving on stainless steel, mainly by adjusting the frequency. He suggests having more examples for different materials would be helpful.

Expressing gratitude to Commarker for providing him with the machine for an honest review, he discloses the presence of affiliate links in the video description, which may benefit the channel if viewers choose to make a purchase based on his review. Nevertheless, he assures that his opinion remains unbiased regardless of any potential affiliation.

The introduction concludes with a reference to his previous videos, hinting at a continuity of content for viewers familiar with his channel.

Mopa’s Laser Principle.

You may have come across the review I conducted on the laser’s smaller counterpart, also named the Commarker B4 for some reason. However, this machine differs significantly. Not only is it physically larger than the other B4, but it also utilizes a different laser power source known as a MOPA laser, standing for Master Oscillator Power Amplifier. Without delving into intricate technicalities, unlike regular diode or CO2 lasers that primarily rely on speed and power for engraving and cutting, a fiber laser incorporates power, speed, and frequency to mark surfaces.

With a MOPA fiber laser, an additional adjustable feature called pulse duration is introduced. This provides flexibility in working with different materials by delivering high energy in potentially shorter durations, thereby minimizing heat generation. This feature is particularly beneficial for engraving delicate materials like certain plastics that are sensitive to high heat. Moreover, it can produce more reliable color results on stainless steel and titanium. The MOPA laser also offers a wider frequency range, providing more options for marking materials.

In terms of construction, the machine is a single unit, unlike its smaller counterpart. It’s evident that this laser machine brings a host of capabilities and advantages due to its MOPA technology, setting it apart from traditional laser systems.

Machine Features

In terms of features, the machine offers versatility and ease of use. Attaching the included focusing bracket allows for straightforward operation by holding the handle on the top. While it can be handheld, it’s not exactly portable due to its weight and the need for a computer connection to operate. Although handheld operation isn’t planned, it’s appreciated to have the option available if needed.

The head of the laser features buttons labeled “R” for framing work and “M” for starting the job, providing convenient control options. Additionally, there’s a power button, along with buttons for adjusting the vertical movement of the laser and an emergency stop button for safety.

The machine comes with two different lenses, altering the workable area. The 110 mm lens, installed by default, offers a workable area of approximately 110 mm x 110 mm. Switching to the 200 mm lens expands the workable area to about 200 mm x 200 mm, although with a larger and less powerful laser spot. Various interchangeable lenses, ranging from 70 mm to 200 mm, are available for further customization.

Two laser pointers in front of the lens aid in proper adjustment, ensuring convergence with the red laser at the correct focal height. A metal ruler provided by the company facilitates accurate measurement of the focal length. The base of the work area features spaced holes for screwing down angle brackets to secure workpieces. Optionally, these holes can accommodate a rotary tool for additional functionality.

An observation regarding the work area is the absence of pass-through holes seen in previous versions. Instead, a metal plate has been added behind the holes to prevent debris from falling into the electronics below, indicating a design improvement for better maintenance and longevity.

Accessories and Specifications

The machine is accompanied by a box containing the driver for rotary tools, although a rotary tool itself is not included as standard. Different rotary tool designs are available for purchase as add-ons when ordering the machine. Additionally, the B4 model includes a foot pedal, facilitating easier and faster operation of batch jobs. Notably, the machine comes with a pair of safety glasses and a laser shield, a welcomed addition that enhances safety during operation.

Operating as a galvo laser engraver, the laser head remains stationary while tiny mirrors within the head adjust to direct the laser beam. This design enables the machine to achieve remarkable speeds, reaching up to 10,000 mm/second. Available in various power options, including 20W, 30W, and even 100W versions, the machine utilizes a JPT M7 MOPA laser source, known for its reliability and quality.

With a precision of up to 0.1 mm, the machine is capable of achieving extremely fine detail. As a fiber laser, it operates at a wavelength of 1064 nm, making it suitable for metals, plastics, stones, and leather, but unsuitable for materials such as paper and wood. The machine can be controlled using both the provided EZCAD software and Lightburn. However, for Lightburn software usage, a galvo license must be purchased separately.

Before delving into the jobs completed with the machine, it’s worth discussing the setup used during testing. This provides context for understanding the results showcased in subsequent demonstrations.

Enclosure

Lasers possess considerable power, capable of engraving metals by vaporizing the surface, creating metal dust. It’s imperative to have an effective fume or dust extraction system in place to avoid inhaling these particles. While Commarker offers an enclosure and fume extractor, their efficacy remains untested by the speaker. For personal use, the speaker constructed a small enclosure from a wooden box, initially crafted on another diode laser engraver. Secured to a base plate, the box features a top hole to accommodate the Galvo laser head. A latchable door at the front provides access, while a variable-speed fan aids in dust and fume extraction. Connected to a powerful inline fan, the setup efficiently removes particles to an outdoor filter. Additionally, a camera is mounted inside for job monitoring, with a fin plate or heat sink underneath to dissipate heat and protect the work surface. Although this setup is detailed for informational purposes, alternatives may suffice depending on individual preferences. An SVG file of the enclosure is provided in the video description for those interested. The speaker’s initial exploration with the machine focuses on achieving colors on stainless steel.

stainless steel

Colors can be achieved on stainless steel using less expensive diode lasers, but the consistency obtained with the MOPA laser is unmatched. By joining the Laser Master Class and Commarker Facebook groups, the speaker discovered test files for marking color on stainless steel. Initially, a color swatch test found in the Commarker group was conducted using EZCAD to ensure the machine’s functionality, yielding satisfactory results. Subsequently, a Cadillac keychain test from the same group was executed, producing pleasing colors. To work primarily in Lightburn, the speaker replicated the EZCAD test values in Lightburn, ensuring parity between the two software. Additional tests and colors were explored based on findings from the Laser Master Class Facebook group.

The results revealed a variety of vibrant colors, albeit some being angle-dependent. Leveraging this knowledge, a color engraving of Mario’s head was created with adjustments made to achieve satisfactory results, except for the red in the hat. While the Mario image cannot be released due to copyright restrictions, a public domain Mickey Mouse file was utilized to demonstrate color engraving capabilities. With the same settings obtained from previous tests, a color version of Mickey Mouse was successfully engraved, showcasing impressive colors and detail. The Lightburn file for Mickey Mouse will be provided in the video description for public access.

Stainless Steel Tests

After feeling confident with the color settings, the speaker proceeded to conduct image tests on stainless steel. Employing similar values as the color test, a highly detailed image of a motorcycle was successfully engraved onto the metal surface. Further experimentation with the values is deemed necessary, as some results were heavily dependent on viewing angles, while others appeared too dark overall. Despite this, the speaker expressed satisfaction with the overall outcome of the tests, acknowledging room for further tweaking and improvement.

Brass Coins 3D engraving

the speaker moved on to their favorite activity with fiber lasers: 3D engraving. This process involves converting a 3D model into a height map, which can be sliced in Lightburn, similar to how a 3D printer operates. For this task, a brass coin blank purchased from Amazon was utilized. Initially, a highly detailed file sourced from the Laser Masterclass Facebook group was attempted, although it proved almost too intricate upon completion. Subsequently, a file specifically designed for this purpose, acquired from Etsy, was employed with the same settings, yielding impressive results. The speaker expressed enthusiasm for 3D engraving due to its capability for intricate detail.

Dust removal was emphasized as essential during 3D engraving, given the pulverized material generated during the process. Moving on from coins, the speaker conducted an aluminum business card test, a task well-suited for fiber lasers. The machine’s included material pack contained such cards, among other test products, with a thickness of almost half a millimeter. The speaker successfully engraved a dog image onto one of these cards using Lightburn, achieving excellent results.

With the engraving tasks completed, the speaker expressed an interest in trying card cutting next.

Card Cutting

For the card cutting experiment, the speaker decided to test the machine’s power by cutting a design out of a card. They utilized an image of an eagle purchased from Etsy and applied the same settings used for engraving, followed by a cutting operation. The cutting was executed at a speed of 2500 mm/s, with 100% power, a 60 kHz frequency, 200 nond C pulse, and 1500 passes. Given that Lightburn has a maximum limit of 500 passes, the job was run three times consecutively to achieve the desired result. The speed was indeed remarkable, with the footage capturing the process without any alterations. However, the camera accidentally obstructed the laser during filming, prompting the speaker to consider incorporating the residual parts into the design as a stand for the artwork. Subsequently, they intentionally left a tab in the design for this purpose, which proved successful.

Additionally, the speaker conducted another test where the cut was fully removed from the card, yielding satisfactory results. Finally, the last test performed on the machine involved experimenting with plastic, although they acknowledged the need for further tests in this regard.

Plastics Testing

In the plastic tests, the speaker aimed to gather data on various materials to establish a comprehensive catalog of settings. Although further experimentation is required, the initial outcomes show promise. They conducted tests on different materials to assess their suitability. Two tests were conducted on travel power bricks, both utilizing identical settings. However, the results varied significantly: one appeared white, while the other appeared dark. This discrepancy demonstrates that the type of plastic used greatly influences the outcome of the markings.

Conclusion

Overall, the speaker expressed satisfaction with the performance of the machine. They acknowledged that working with fiber lasers, especially those with MOPA functionality, may have a steeper learning curve compared to standard diode or CO2 lasers. However, for tasks such as metal marking, engraving, or cutting, fiber lasers offer significant advantages. They emphasized the valuable learning resources available on platforms like the Laser Everything YouTube channel, which provides tutorials and power-speed libraries for beginners.

Regarding cost, the speaker noted that while the reviewed 60W MOPA laser is not cheap, there are options available with lower power and without MOPA capabilities that could be more affordable for those with different needs. They highlighted that the choice ultimately depends on the specific requirements of the user.

In conclusion, the 60W B4 MOPA laser from ComMarker is recommended for those seeking MOPA functionality and features such as consistent colors on stainless steel and a wide range of shades on different plastics. The speaker expressed gratitude to ComMarker for providing the machine for an honest review and invited viewers to explore affiliate links in the description for further support.

Wonder what difference these two laser technologies –Fiber laser and CO2 laser possess?

Well, the big difference comes down to what they’re good at and how they work. In simpler terms, each has its own capabilities and laser strengths, especially when it’s about processing certain materials, thicknesses, and particular applications. Ultimately, all that matters is the material and work requirements in hand.

This blog post will give you a closer look at each of these machines, along with its pros and cons, so that you can make an informed decision.

The Basis of Laser Technology

The laser engraving technology, which is a pinnacle of efficiency and precision, has changed the game of how we used to put patterns and designs onto objects, making modern manufacturing and creative craftsmanship reach unprecedented levels of intricacy and sophistication so that everything looks super elegant.

Yet, within this umbrella, two technological marvels emerge—Fiber and CO2, each with distinct wavelength and capabilities. At a glance, they may share the same purpose of marking design onto the piece of material, but their difference is as stark as day and night.

Take CO2 laser as the master of organic materials that effortlessly work through leather, wood, ceramics, acrylics, and glass with finesse and grace.

Meanwhile, the Fiber laser engraver stand tall as a sovereign of metals that take it concentrated laser beam penetrating steel, aluminium, gold, silver, and brass with unmatched accuracy.

There’s no doubt that the efficiency and versatility of both of these technologies have made them indispensable tools in multiple fields as diverse as automotive, medical, aerospace, jewelry, and signage.

If they’re compared based on technical criteria, they’re dictated by the wavelength they operate at and the material they’re best suited for. A fiber laser usually has a wavelength of 1,060 nm, while CO2 lasers have wavelengths in the 10,600 nm range. In general, fiber lasers have many advantages over CO2 lasers.

This fundamental contrast in their strength shapes the choice of artisans and industries alike, determining its optimal use for realizing their creative visions and manufacturing needs.

Section 1: Differences Based on Technology and Operation

-Understanding The CO2 Laser Engravers

While your CO2 laser is at work, know that there’s a system working based on the principle of stimulated emission of radiation within a carbon dioxide gas mixture. This exactly made the system work when the CO2 gas mixture is energized within a sealed tube using an electric current discharge.

The excitement of these gas molecules causes them to reach higher energy states, followed by the emission of photons, resulting in an amplification of light within the laser cavity and, ultimately, a coherent and concentrated light beam.

The wavelength at which the CO2 laser engraver operates falls in the mid of the infrared range, recording a wavelength of 10.6 micrometres (µm). This range has significant implications for material interaction during engraving, allowing wood, leather, ceramic, glass, cloth, and acrylic to be ideal substrates for light absorption.

However, metals are not their good friend, because the long wavelength makes them insufficient in penetrating the metal surfaces, where less precise engravings and slower processes are often the results.

– Understanding Fiber Laser Engravers

While we scrutinize the workings of Fiber laser marking machine, we come to know that they’re a product of modern optical engineering and are distinguished by their utilization of doped Fiber optic cables. Within these cables lies the unique infusion of rare-earth elements that give the Fiber its laser-making powers.

Here’s how it works– the operation mechanism of Fiber engravers begins with the introduction of energy within the doped Fiber, activated through either electrical stimulation or optical excitement. This infusion of energy causes a state of heightened activity among the embedded rare-earth elements, which, as a result, emit photons, generating coherent and concentrated laser beam characteristics of Fiber models.

Unlike its CO2 counterparts, Fiber laser systems discharge light at significantly shorter wavelengths, typically at 1060 nm, located near the infrared spectrum. This divergence in wavelength, a reason for their distinct operational principle and materials, allows this laser unit to be compatible with all metal substrates.

Metals, being receptive to these shorter wavelengths, respond well to the laser beam, rendering the Fiber laser system unparalleled in efficacy with engraving on brass, aluminum, gold, stainless steel, silver, and leather, you name it.

Thus, both of these technologies are a testament to their intricate interplay of wavelength and material interaction, given that our CO2 laser is a perfect machine for processing organic materials and the B4 Fiber laser as a top choice for application in the category of metalwork.

The most highlighted difference between Fiber and CO2 laser markers is the wavelength of light they produce. Short wavelengths typically have more energy and a higher absorption rate than long wavelengths. As a result, a laser’s wavelength affects its ability to mark certain materials.

Lasers with these distinct functional capabilities have shown their effectiveness across various domains, not even leaving a basic DIY enthusiast.

The way these laser optics have refashioned how metals are now precisely carved and marked with pinpoint accuracy is remarkable, but here’s a burning question: “How Deep Can these cutting-edge laser machines engrave metal?”

Now, before we move ahead, it’s crucial for one to know that the depth Fiber laser marking machine can reach depends on a bunch of things, such as material structural composition, laser parameters, and surface preparation.

Once you’ve got a clear understanding of what depth it can go, you can work your creativity across many domains and leverage this for multiple applications, so let’s buckle up and delve together into the science of advanced optical principles and high-powered laser beams so you can squeeze the last drop of potential out of these machines for engraving metal.

Understanding Fiber Lasers

When you enter the engraving world, you’ll probably hear about Fiber laser systems being the most talked about. This is because they’re the most stable choice for marking, which makes use of optical fiber to amplify light and create an incredibly powerful beam that works around multiple sets of materials.

Here’s how it works– the process all starts with the activation of tiny fibers packed with laser-active materials when the power supply is provided. This excitement allows them to emit photons (tiny particles of light ) that bounce back and forth inside the fiber, getting more amplified with each bounce. When they’re at their peak, they burst out of the fiber as a concentrated laser beam.

The reason why you should consider Fiber laser machine as your first choice can be justified by their host of amazing benefits. First off, these laser models, especially the ComMarker B4 model, are super precise and accurate. You can even relate to the microscopic-level precision here. This means you can carve out even the tiny details on metal surfaces without compromising quality.

Not only that, but these powerful systems are crazily fast, processing through materials in the blink of an eye. This speediness allows operators to save time and work on more pieces in less time, so you can easily cater to higher volume jobs.

And let’s not forget about versatility. Fiber laser units are compatible with a wide range of metals, including stainless steel, aluminium, brass, and every metal you name. So this would be exciting news for one working with jewelry, custom signage, industrial parts, or product traceability, taking the engraving game to a whole new level.

Factors Influencing Engraving Depth

While standing at the helm of our B4 Fiber laser system, ready to carve your favorite piece of metal into a masterpiece, we’ll all know that all it takes is just the press of a start button. But wait, while you’re dealing with depths, it’s not as easy as it seems.

There are various factors that influence this engraving part, and it’s a way too crucial for the operator to understand all these parameters beforehand.

– Power Of The Laser: How Wattage Affects Depth

It’s pretty sensible that laser power is the core component of the system that acts just like the engine of a car. It denotes the energy a laser beam delivers within a specific timeframe, and it varies according to the laser type and architecture.

Know that this parameter is the most crucial to meet cycle time requirements. A 500W laser may not be five times faster than a 100W, but it’s still much faster.

Spanning from a few watts to several kilowatts, the machine’s laser power would make you roughly calculate the intensity of the beam, thereby affecting the engraving processes’ speed, depth, accuracy, and versatility.

Machines with more horsepower and wattage can etch thicker metal going deep at an approximate depth of 0.3mm and create more intricate designs faster, so If you’ve got an engraving metal that’s thicker and harder, grab a higher-powered machine such as the 100W B4 Fiber laser engraver and get your job done.

Most deep engraving applications require at least 100W. At ComMarker, we provide different types of lasers. Our high-power Fiber laser starts at 100W. We also offer a 20W, 30W, and 60W fiber laser, a less powerful range for sensitive metals.

– Type Of Metal: Variations In Metal Properties And Their Impact

When you plan to engrave metal, the same working formula isn’t applicable to all. Each metal has its own set of properties, and when the laser beam interacts with them, it responds differently to each of them.

Metals properties, from hardness to conductivity, can either make engraving a breeze or a bit of a challenge. Stainless steel, for example, might need a bit more energy from the laser to get those depths just right, while softer metals like aluminum might require a lighter touch.

– Speed Of Engraving: Balancing Speed And Depth

It’s quite common to confuse speed with frequency, but they’re two different parameters. Frequency is how many times the laser beam hits the target in a given period, whereas speed refers to the speed at which the laser beam moves.

A slower speed means that the laser beam remains longer over the same area, resulting in an increase in the amount of energy in that area, allowing you to engrave deeper and faster.

But there’s a point where too much energy may overheat and discolor the surface. That is to say, finding a delicate balance between going fast enough to be efficient yet slow enough for those marks to sink in just right. Too slow, and you risk burning through the metal; too fast, and you might not get the depth you’re looking for.

As you work with deep engraving, keep this general rule in mind: reduce the engraving speed of the machine so you can extend the time the laser stays on the surface of the object, allowing for greater penetration into the metal.

– Focus Of The Laser: Optimizing Laser Focus For Depth

As surprising as it may sound, the focal lens of the Fiber laser machine is also one of the impacting forces of deep metal engraving.

Just like your camera lens, where you focus it right to make all the difference, optimizing the focus of the laser, you let every ounce of fiber energy to concentrate exactly where you need it, maximizing the depth of your engraving and leaving a lasting impression.

The Lenses control how the laser beam is focused, and only a highly focused beam can reach the intensity required for deep engraving. Using the right lens can effectively double the engraving speed.

Typical Depths Achievable with Fiber Lasers

In reference to distinguished material properties and their alternative responses to laser energy, the estimation of the marking depth that can be achieved with these laser machines also varies.

We already understand that laser parameters and application-specific requirements also affect laser marking depth, so keeping that in mind, here are the maximum depths achievable with various common materials:

• Steel: Laser marking on steel can typically achieve a depth of 0.01mm to 0.5 mm, but this can alter as per the steel’s composition, surface finish, and laser parameters. This depth can get you to mark clear and durable patterns, logos, serial numbers or other identifiers on steel surfaces without compromising the structural integrity.

• Aluminum: Compared to steel, aluminum has reflective properties that typically result in shallower marks, ranging in depth from approximately 0.3mm with 30W power. Anodized aluminum surfaces can sometimes provide deeper marks due to their enhanced surface reaction with the laser.

• Silver: Silver is known for its shining appearance, enabling marking depths between 0.01mm and 0.2mm. Due to its high reflectivity, achieving deeper marks may require specific laser settings and techniques.

• Brass: It’s a copper-zinc alloy that gets the fiber laser beam get absorbed upto 1.06 microns. It has some good heat dissipation properties, so engraving become very handy. Though it is a highly reflective material, it will only be worked by our Fiber laser model.

 Maximizing Engraving Depth

Maximizing engraving depths on metal is like unlocking the hidden treasures of Fiber laser machines. With higher peak power and focus length adjustability, they work tremendously well with metals and produce high contrast and deep marks.

With that said, there’s still a need to navigate some areas carefully to ensure success. Here are some tips to ensure you achieve those engravings while maintaining the quality.

Consider Material Composition:

When the task of engraving is performed, all it comes down to the material used during the process. It’s well understood that not all metals are created equal. Metals that are susceptible to corrosion are more difficult to engrave.

Deep engraving stainless steel and iron fall into this category. Both iron and stainless steel corrode faster from an exposed inside. Especially since stainless steel naturally has a protective layer, the engraving disrupts it.

If you plan to use a deep metal laser engraving machine on these metal types, consider adding an anti-corrosion seal after engraving.

Use Multiple Passes:

Sometimes, getting your laser beam to pass through the metal once is not just enough; it requires your Fiber lasers to perform multiple passes to achieve your desired level of output. In such cases, gradually increasing the laser power and allowing multiple engraving sessions is all you need for that level of depth. Meanwhile, you do have control over the process just to maintain the quality.

Optimizing Laser Settings:

Fine-tuning the laser parameters is the optimal secret to achieving deep engraving. Find the sweet spot between frequency, power, speed and focus of the Fiber laser system to have metals pop like a masterpiece. You can experiment with different settings as a test to strike the perfect balance between depth and quality.

Select Shorter Focal Length:

Since the lens contributes majorly to the engraving task, picking the right one is what it entails. The right one means here lens with a shorter focal length to let the concentration of the laser beam be more tightly, allowing for a deeper penetration into the metal.

Cooling and Ventilation:

Deep engraving can simply translate as the high heat emitting process; arranging for cooling equipment and a well-ventilated working space becomes a necessary part of your task. This practice would significantly prevent metal from overheating and ensure consistent quality, especially at greater depths.

Consistent Monitoring and Adjustment Upon Need

Since deep metal engraving is a delicate task, your attentive eye should witness this all as the machine goes deeper. Keep a check on the beam quality, surface temperature, and engraving depths, and be ready for any immediate adjustment to the settings or techniques as to maintain the quality throughout the process.

Applications Requiring Deep Engraving

Opting for Fiber laser systems as your choice of tool for deep metal engraving opens up many avenues across a multitude of industries and applications. So, whether you be a contractor, industrial manufacturer, site manager, or even someone with a spark of creativity, this machine serves all.

Not only do you get to see these machines showing their potential in commercial or industrial setups, but this has far reached the doors of creative homeowners.

Let’s explore each with more detail.

– Industrial Uses:

In the industrial realm, deep metal engraving is all about functionality. Imagine those engraving machines intricately marking bar codes and serial numbers on workpieces for traceability, brand logos stamping on products for identity, or even compliance markings to show they meet regulatory standards.

And while your grocery cashier scans through your products, the barcodes you see are the result of deep laser engravings, making the whole process much smoother and more efficient.

Even the fine jewelry you purchase for your loved one with engraved messages, personalized inscriptions, or a person’s initial– these are all crafted by deep engraving technique, so those receiving them can find them unique and meaningful.

Your aerospace, electronic, and medical industry isn’t out of this. The deep marking facilitates these industries for assembly, maintenance, and branding of these equipment, leaving a durable and precise mark that holds both aesthetic and sentimental value.

– Artistic Applications: Customization And Decorative Engraving

In the category where creativity and artistry prevail, deep laser engraving emerges as a captivating medium where the collaboration of laser technology and craftsmanship yields breathtaking results.

Every pulse of the laser beam hits with accurate precision and depth as artists get down with their metal laser engraver to mark inert metal surfaces, turning them into jaw-dropping pieces of beauty right in front of your eyes.

Whether it’s enhancing your everyday metal objects like tumblers, keychains, or dog tags or even marking your favorite metal phone cases, cutlery, or watches, deep engraving seamlessly integrates into these objects, serving practical, aesthetic, and personalization purposes in various domains.

 Limitations and Challenges

– Physical Limits To Engraving Depth With Fiber Lasers

When leveraging Fiber laser models as your engraving tool for deep metal engraving, there are some hurdles and roadblocks to watch out for. First off, the physical constraints of the machine to reach a certain depth point and the strength of the metal to absorb the laser beam put you in a major thought process.

Though our Fiber laser models are well-designed to carve metals with intricacy, there’s always a limit to how far they can go deep without things getting messy.

This depth science completely changes as the laser parameters vary, such as laser power, wavelength, pulse duration, and the type of metal put into place. Exceeding these depth limits may make your engravings a whole disaster, and you can end up having metals with inconsistent marks.

– Technical Challenges In Deep Engraving

Fiber lasers are powerful tools that often need your technical proficiency to be at a higher level. By this, we mean the skill and patience to do this kind of engraving job. Deep metal engraving requires perfect laser parameters adjustment, thereby demanding an operator to prevent the laser beam from going too shallow or even not too deep.

Here, it’s all about maintaining consistency. If the heat goes too high, too much of it can cause everything out of the track, making your metal warp or your engraving look faulty. So, juggling between the perfect laser settings in terms of speed and power is crucial to remain under control.

Also, the variation of metals has different responses under the laser beam, so what might work for one might not work for another. It’s all about activating your technical abilities to master this skill of art.

 Conclusion

As we’ve seen, Laser engraver are such versatile machines that have found their way into almost every industry. Serving as tools for engraving, cutting, welding, and texturing, to name a few, it has a lot of practical and industrial applications.

Amidst its processing methods, deep laser engraving stands out as a subtype of engraving that calls for different settings than typical engraving. However, that doesn’t mean you need a different machine. Though the working principle is almost the same, they’re likely to differ in laser power and speed.

Deep engravers take just a lil bit more time to create an impression on metal components and Instruments. However, the engraving depth is so clean and impressive that it gives a significant visual effect and a great feel to the touch.

All right, welcome back to the Redbeard Ops Workshop . Today, he is going to be reviewing a fiber laser from ComMarker. He had seen some other YouTubers using ComMarker B4 laser engraving machine , and that gave his the confidence to collaborate with ComMarker for a review from the perspective of a knife maker. As you all know, he has reviewed the Xtool 20W diode laser engraver in the past, and he will be getting into what differentiates these two laser machines later in the video.

While putting the machine together, it’s impaortant to note that these lasers are not toys and can cause damage to your eyes or lungs, depending on what you’re engraving. The laser comes with a set of protective glasses, but they ended up ordering another set that is certified and will protect them with both lasers in their shop since they have different wavelengths. The 190nm to 550nm range will cover the diode laser, and 800nm to 1100nm will cover this fiber laser. Additionally, he emphasizes the importance of keeping the shop ventilated and potentially using a fume extractor if engraving toxic materials or working in high volumes.

As you just saw, the assembly was very straightforward, especially in contrast to putting together the Gantry on the Xtool diode laser. The only movement this fiber laser has is in the Z-axis in order for a user to focus it.

Preliminary Understanding

RedBeardOps hadn’t been satisfied with the quality of the plastic fences that came with ComMarker B4. Consequently, he took it upon themselves to design replacements using Fusion 360, intending to print them out on their Bamboo Labs P1S. Additionally, they designed a 3D printed stand for the rotary attachment, which they planned to attach to the laser bed since it tended to hang off the side during use. They mentioned that free links to these print files would be included below in the description.

ComMarker B4 includes a USB stick with the necessary drivers and a copy of ezcad to facilitate setup. However, as RedBeardOps is already a Lightburn user, he opted to upgrade to the galvo version of Lightburn software, which is required for fiber laser engraver . Although he decided not to delve into the mundane details of computer setup, he indicated that an installation guide link would be provided in the cards and/or description below.

Before proceeding with knife steel depth testing and maker marks on knives he cared about, RedBeardOps wanted to acquaint themselves with commarker b4 laser marking machine .

In the segment about laser bed alignment, RedBeardOps mentions that the ComMarker laser engraver cames with a pack of sample materials, such as business cards and dog tags, which are suitable for testing purposes. He quickly noticed that his laser wasn’t aligned with the fences. To address this issue, he lined up one of the business cards with the fence and etched a horizontal line on it using Lightburn software . Adjusting the alignment was a simple process that involved loosening the column bolts and gently turning the column counterclockwise within the tolerance of the mounting holes.

He then experimented with the settings using a chrome dog tag from the sample pack. After some trial and error, he found the optimal settings that resulted in a dark and deep etch into the dog tag. He emphasize that achieving the desired results often requires experimentation and sacrificial materials.

Feeling confident after successfully etching the dog tag, they express their intention to personalize some tools, which they believe can be useful not only as gifts but also for keeping track of tools in a multi-person environment.

RedBeardOps acknowledges an issue with the Red Dot preview frame not lining up with the final result on steel. Although he resolved this issue after shooting most of the footage, he mention that there is a software solution in Lightburn settings to offset the frame, ensuring accurate alignment.

Finally, he remark that the laser performed well in etching both brass and aluminum materials.

Material Testing

Brass & Aluminum

In the discussion about etching brass and aluminum, RedBeardOps expresses his impression with the laser’s performance, particularly in etching these materials deeply. He notes that he has observed others using the fiber laser for etching brass coins, which leads him to believe that with enough time, it could be utilized for creating custom brass leather stamps or similar items.

RedBeardOps mentions the simplicity of focusing the laser using the Z-axis motor, where one aligns the material on the bed and adjusts the laser head until the three dots overlay each other. He demonstrates this process by etching his vice jaws to showcase the laser’s performance on aluminum. Additionally, he intends to incorporate some branded elements into the background of his hand sanding footage using commarker b4 fiber laser engraver .

Moving forward, He expresses his  intention to continue testing different materials and settings with commarker b4 20w laser marking machine .

Leather & Wood

When discussing etching on leather and wood, RedBeardOps mentions that a fiber laser engraving machine  is not particularly suited for these materials. Its higher wavelength makes it ideal for metals, but it tends to underperform compared to a diode laser when it comes to natural soft materials. Although some people have achieved success with leather etching using a fiber laser, RedBeardOps believes it requires a significant amount of time to fine-tune the settings. He demonstrate their experimentation on a test piece, showcasing a range of light to ultra-dark marks.

Additionally, He notes that the performance on wood is also subpar. For those interested in etching wood and leather, RedBeardOps recommends opting for a diode laser like the 20W Xtool, which he has previously reviewed on his channel. This recommendation extends to cutting applications as well. If one intends to cut out sheath templates or custom wood boxes, a diode laser is the preferred choice.

Before transitioning to knife steel testing, RedBeardOps highlights the rotary tool and its functionality.

Rotary Tool(Tumbler)

When discussing the performance of the fiber laser on tumblers, RedBeardOps highlights his popularity for engraving purposes, whether as gifts or for creating custom merchandise for shops. He recounts spending hours figuring out the right settings for Yeti tumblers on the machine and hope that sharing his insights will assist others looking to undertake similar projects. Noteworthy is the mention of focusing the laser at the apex of the cup and employing a small split on the rotary tool settings. He also mentions running multiple passes at lower power to avoid marking the underlying stainless steel and only burn off the powder coat. He emphasizes  the importance of proper ventilation when using the laser in the shop.

Regarding the potential rotary application for knife making, RedBeardOps speculates that it could potentially be used to engrave pommel nuts but admits to drawing a blank on other potential uses in the shop. He invites viewers to share any ideas they may have in the comments section.

In conclusion, RedBeardOps indicates that they have now familiarized themselves with the machine and are ready to proceed with their planned activities.

Knife Steel Initial Testing

In the process of testing knife steel with the machine, RedBeardOps begins by taking a piece of 104 bar stock and initiating test grids for speed and power using Lightburn’s built-in testing panel. He mention the ability to vary the interval and frequency for fiber lasers, starting with a general spot. Subsequently, they commence running iterations of their maker mark on the test piece to evaluate the sample etches.

After completing the etching process, RedBeardOps transfers the bar to his sanding bench and removes the soot around the edges with sandpaper to assess the depth of the etch. Noticing that the first batch of marks was washing out, they realize the need to increase the laser duration with multiple passes. They point out running a relatively low power setting to avoid edge discoloration around their mark, though they acknowledge the necessity for further testing to confirm this theory.

Upon completing the second batch of maker marks, RedBeardOps is pleasantly surprised by the improved outcome, particularly noting the cleanliness and depth of the third mark. They express their astonishment at the quality achieved and hint at further testing in the future to refine their process.

Depth Testing VS Electro Chem

In order to provide a comprehensive comparison, RedBeardOps decides to conduct depth testing between the fiber laser, their normal electrochemical etching method, and the diode laser. He explains their methodology, which involves etching small rectangles onto a piece of stainless steel using Lightburn software for the lasers. For the fiber laser, they run tests at both 10 and 20 passes, noting the time taken for completion. He observes that during the longer etching cycles, the bar stock becomes slightly warm.

For the diode laser, He adjusts the size of the rectangle to save time, as it etches slower than the fiber laser. Despite running it at 90% power and 5 mm/second, the diode laser yields shallow etches compared to the fiber laser.

Upon inspection, he expresses slight surprise at the depth achieved by the diode laser, noting that previous tests on carbon steel resulted in a darker finish. They proceed to compare the results with those obtained from their DIY electrochemical etching machine, which typically produces deep and dark etches.

After performing the tests, they clean the test bar with sandpaper and measure the depths of the etches. The 10-pass fiber laser etch reaches a depth of approximately 1/2 thousandth of an inch, while the 20-pass etch reaches 1 and 1/2 to 2 thousandths of an inch. In contrast, the diode laser etch does not register any significant depth, and the electrochemical etching machine achieves a depth of around 2 and 2 thousandths of an inch.

Overall, RedBeardOps finds the results from the fiber laser promising, as additional passes could easily increase the depth if needed. They conclude by acknowledging the depth achieved and expressing satisfaction with the laser’s performance.

Etching KNVIES

With the knowledge gained from their previous tests, RedBeardOps proceeds to etch actual knives. They mention a recent buoy build where they used the laser to imprint their maker mark on the ricasso. Expressing satisfaction with the ease of alignment and the etching performance, they note running 20 passes on the mark but wish they had done a few more for a slightly deeper etch. Despite this, they consider the mark acceptable.

They then turn to an old knife they made based on Knife Talk build-along plans, using it to compare the fiber laser mark with an electrochemically etched one. After cleaning the knife’s side without the electrochemical mark, they etch it with the fiber laser using 20 cycles, consistent with previous tests. Upon inspection with a digital microscope, they note significant differences in precision and cleanliness between the two methods.

Impressed by the fiber laser’s performance, RedBeardOps considers various applications such as labeling materials used in builds, personalizing blades for customers, or leaving hidden messages on knife internals. They express excitement about the machine’s capabilities, which they plan to use for etching their maker mark in future work, replacing their electrochemical etching machine.

To conclude, they provide affiliate links to the laser and free 3D print files mentioned earlier in the video and invite suggestions for future laser experiments or improvements in settings. Finally, they express gratitude to ComMarker for providing the machine ComMarker B4 20w laser engraver  for review and for use in his workshop.

Commarker also thanks Redbeard Ops Workshop for being willing to share the adaptation he made with us. If you want to learn more experience with engraving tools, you can click on this link to consult Redbeard Ops Workshop   https://www.youtube.com/watch?v=rRrAhYeloCc 

What’s Rust

First, he explained to us what rust is, and he intends to use a Commarker B4 fiber laser engraver machine for rust removal.

Rust is a reddish-brown or orange-yellow substance that forms on the surface of iron or steel objects due to a chemical reaction between iron and oxygen, commonly known as oxidation. Specifically, when iron reacts with oxygen, it forms compounds known as iron oxides. This process is often accelerated in humid environments where water can speed up the oxidation of iron. Rust typically appears as a powdery or flaky substance covering the surface of iron or steel objects, giving them a corroded appearance. It not only affects the aesthetics of the metal but can also lead to a loss of strength and durability. Therefore, preventing and treating rust is crucial for preserving the quality and longevity of iron or steel objects.

Principle of laser rust removal

The principle of laser rust removal is based on the high energy and high focusing properties of lasers, as well as the optical characteristics of the oxide layer and the metal surface. The main principles include the following:

1. Optical absorption: When a laser beam is directed onto the surface of a metal, the oxide layer (such as rust) absorbs the energy of the light because of its darker color, making it more prone to absorbing light energy.

2. Thermal effect: The absorbed light energy causes the oxide layer to rapidly heat up. Once reaching high temperatures, the oxide layer begins to decompose or evaporate. This high temperature causes the oxide layer to detach from the metal surface and be evaporated or ejected under the action of the laser beam.

3. Optical selectivity: Laser beams can be highly focused, allowing precise control of the area affected by the laser. This means that the laser energy is concentrated only on the oxide layer to be removed, without causing damage to the metal surface.

In summary, laser rust removal utilizes the high energy and focusing properties of lasers to precisely concentrate light energy on the oxide layer on the metal surface. This results in heating, decomposition, or evaporation of the oxide layer, achieving cleaning and rust removal without damaging the metal itself.

Thermal Expansion

Thermal expansion occurs when subjected to high temperatures due to the energy, although this happens on a microscopic scale, hence why the metal doesn’t visibly melt. The intense heat also induces thermal expansion in the rust at a significantly faster rate than the underlying metal. This discrepancy in expansion, coupled with the extreme heat, causes the rust to break its bond with the metal surface. Subsequently, the rust particles can either vaporize or be forcefully ejected from the surface. By fine-tuning the laser settings, one can target the rust layer without causing damage to the underlying metal. When using a fiber laser, three primary parameters can be controlled: speed, power, and frequency. Fiber lasers have the capability to produce very high peak powers, reaching tens of kilowatts, by concentrating the energy delivery into short, rapid-fire pulses. Even low-powered fiber lasers can effectively remove rust layers through a series of micro-explosions generated by the rapid pulses. These quick pulses help prevent overheating of the underlying base metal. For rust removal, it is advisable to use low-frequency settings, as higher frequencies may not deliver enough energy to induce ablation on the surface.

Conclusion

In conclusion, it is advisable to also use low power at low frequencies, as high power at low frequencies may not be optimal for the components inside the fiber laser. Additionally, it is recommended to set up a fume extractor to remove the generated fumes. Here are some of the attempts made using the 20W fiber laser from Commarker. The settings used will be displayed over the video to demonstrate the contrast between rust removal using sandpaper and laser. This showcases the effectiveness of removing rust using a fiber laser.
