Laser Safety: How to Laser Engrave Safely at Home

Your laser cutter is a very useful tool that can create some amazing items. As you learn to use it, you will become more creative and be able to experiment with an ever-increasing range of materials and designs — whether cutting engraving, or a combination of both. However, there are several laser safety hazards associated with the home laser cutter that can raise laser cutting health concerns and they need to be fully understood before you start.

If you want to learn more, please visit our website Tiper.

This laser cutter safety article should help you understand all of the laser hazards and allow you to operate your laser cutter safely — not only for yourself but also for those around you.

How a Home Laser Cutter Works 

Almost all laser cutters contain a Laser Hazard Class 4 device, which means they are quite powerful and can cause permanent injury, so an understanding of how they work will help you understand and manage laser safety risks.  

The CO2 laser cutter uses a glass tube that is filled with inert gasses and connected to a very high voltage power supply. The light is generated inside the glass tube and laser radiation is emitted from one end and then bounced off a series of mirrors until it reaches the laser head, where it is focused down to a tiny dot on the workpiece being cut or engraved.  

The head is mounted on rails that are moved by powerful servo motors so that the laser can cut or engrave the design.  

A Diode Laser works similarly except that the blue or green laser radiation is created by a semiconductor diode. A Fiber Laser uses a semiconductor and optical fiber combination to create the IR light source but then uses a single mirror that is moved by a set of servo motors.  

Are Home Laser Cutters Safe to Operate?

Yes, home laser cutters are safe to operate. While there is a laser hazard present, home laser cutters are designed with many safety precautions to minimize laser cutting health concerns. As long as you take the correct precautions, home laser cutters are quite safe. When it comes to laser safety, it's the responsibility of the user to know the relevant laser dangers and utilize the necessary PPE for laser cutting. Read the user manual and carefully observe all of the laser safety measures. Over time, you will get used to a regular procedure of setting up and running the laser safely.

When do most injuries occur when working with laser cutters? 

Most laser cutter-related injuries occur during laser mirror alignment. Laser mirror alignment is when the laser mirrors are being aligned. There is a great temptation to operate the laser with the cabinet door open, the safety interlock disabled, and hands moving around inside the cabinet. This is a highly dangerous practice and should be avoided. It only takes a few extra seconds to close the lid and operate the laser safely. Even the biggest laser safety threats can be mitigated with the correct precautions.

Light Wavelength

Visible light is electromagnetic radiation with a wavelength between 400 and 700 nanometers (nm). That might not mean a lot to you, but the changing wavelength generates different behaviors in materials and is what causes your eyes to see different colors as that light hits the retina. The rainbow, for example, ranges from 420nm to 680nm — what we refer to as “visible light”. Outside of these numbers, light is referred to as Ultraviolet (UV) at the low end and Infrared (IR) at the top end.

How Laser Light Works

Anything that generates light, such as your household lightbulb or the sun, produces light in all directions and typically with a range of wavelengths. This is how we see and observe what is around us. Laser devices, however, generate an intense beam of laser radiation that is all traveling in the same direction and with almost all of the light being of one specific wavelength.

A green diode laser is 532 nm, while a Fiber Laser is between 780 nm and nm. A CO2 Laser is 10,600 nm.

Laser Radiation Safety  

What Is Laser Radiation?

All lasers emit radiation in the form of light. In fact, a laser beam itself is a form of radiation, as the word laser is an acronym for Light Amplification by Stimulated Emission of Radiation. You don’t need to spring for your Geiger counter, however, as today’s home laser cutters are not nuclear-capable.

The term laser radiation doesn’t typically refer to the actual laser beam. Laser radiation occurs when the laser beam strikes an object and the object’s surface does not fully absorb the laser beam; some of the light energy is reflected or refracted back in random directions. This type of laser radiation can be hazardous, and even seemingly matte materials, such as wood, can produce harmful laser beam reflections.

Is Laser Radiation Harmful?

Laser radiation, because of its wavelength and the concentrated beam that is generated,  can be harmful. The main threat that laser radiation poses is to your eyes.

However, when proper laser safety procedures are followed, you should remain completely free from laser radiation while operating your laser engraver machine. Additionally, laser hazards can vary depending on the type of laser.

Different Types of Laser Engraver Hazards

Diode Laser Hazards

The most hazardous laser radiation is that generated with a blue or green diode laser. Diode laser light at 532 nm is not blocked by transparent materials such as the lens of the eye but passes through it until it meets the retina.

The retina absorbs the energy from the laser light and is damaged irreversibly. This can happen in less than 1/th of a second, faster than the eye can blink. Blue laser light is more damaging than green although both can cause permanent damage to the eye.

CO₂ Laser Hazards

CO2 lasers generate laser light at a wavelength of 10,600 nm which is right up in the infrared (IR) spectrum. Unlike the blue/green diode laser light, this is completely invisible which means that extra care must be taken, however, it is also blocked by almost all materials including the lens and cornea of the eye. When IR light hits an object, it heats that surface up. This is how the CO2 laser cuts and engraves, by heating the surface until it vaporizes.

However, it does take a small amount of time for the material to absorb enough light energy for this to happen and so whereas an indirect flash from a reflected blue/green diode laser can cause immediate laser cutter eye damage within 1/th of a second, the same from a CO2 laser is less likely to cause permanent damage. However, all laser light is hazardous and following the safety advice is essential. Looking directly at a laser radiation source will cause permanent eye damage.  

How to Laser Engrave Safely at Home

Most home laser cutters are rated as laser safety Class 4, the highest laser hazard class, meaning the device is hazardous. Before you start, always read the manual, especially the Laser Hazards safety sections, and observe the warning labels on the machine.

Make sure that you understand exactly how your laser machine operates so that you can avoid hazards and minimize any unnecessary risks. When used as designed, the laser cutter safety is considered Class 1 - safe for operators and bystanders.

Where to Set Up Your Home Laser Cutter: Environment Conditions

One important factor is where to locate your Laser Cutter. Your user manual will give you any specific things to bear in mind, however generally the chosen locations should be:

• Stable, level, dry, and climate-controlled with an ambient temperature of 40–75°F
• Ambient humidity under 70% and not close to the dew point (to avoid condensation).  
• Out of direct sunlight
• Free of dust and other airborne pollutants  
• Well ventilated  
• Away from children; combustible, flammable, explosive, or corrosive materials; and sensitive EMI devices.
• The power cord should be plugged into a stable power source with a grounded 3-prong outlet. No other item should be drawing current from the same fuse.  
• Keep fire-fighting equipment nearby.  
• Keep an extra work table nearby to avoid placing objects on or directly adjacent to the machine, which could become a fire or laser hazard.

Avoid Laser Cutter Eye Damage

Is it safe to look at a laser engraver? Can a laser engraver hurt your eyes? 

The answer is that it depends. You must never look at a green or blue diode laser without wearing the correct Laser Safety Goggles, however, a CO2 laser is perfectly safe when operating correctly with the cabinet doors closed and following the laser engraver safety rules. 

Both types of laser can permanently damage your eyes and other parts of your body if you hypothetically took a direct hit from the laser beam — so always follow the laser engraver safety rules. NEVER look directly at a laser beam — it will cause permanent eye damage.

Which Laser Safety Glasses should I buy?  

If you are using a blue or green diode laser, then laser safety goggles are made for these, specific to the frequency of the diode being used. It is essential that you use the correct ones. CO2 laser safety glasses are made in a much wider range of styles and are made from polycarbonate — the same material that the viewing window of your laser machine is made from. This absorbs the IR laser light.

Laser Safety Glasses should be made to either ANSI Z136 or EN207/208/ standards. Good Laser Safety Glasses have an Optical Density (OD) of at least 4 and preferably 6+.

Note that Safety Glasses are meant to protect you against incidental laser light that might be reflected off a metal surface. They are not designed to protect you from looking directly at a laser beam so never, ever, look directly at a laser beam.

Avoid Laser Safety Hazards for Diode Lasers

If you are using a diode laser, then specific laser safety glasses for laser engraving are essential at all times. These must be specific to the frequency of the diode laser being used and need to completely envelop the eyes. Laser cutter eye damage can occur in a fraction of a second and is permanent. Steps must be taken to exclude people and animals from the room being used whenever the diode laser is in use. Each operator must have their own PPE for laser cutting such as Laser Safety Glasses to prevent laser cutter eye damage.  

Avoid Laser Safety Hazards for CO₂ Lasers

CO2 lasers pose slightly less of a problem as long as the standard laser safety systems are in place. Your CO2 laser is built into a metal box with a clear polycarbonate window.  The polycarbonate will block the IR laser light when the lid is closed. A safety switch is built into the lid which stops the laser from firing if the lid is open. Although there may be an override switch on the control panel, it is highly recommended that the safety is not switched off. If you do need to disengage it, then you must wear approved Laser Safety Glasses specific to the CO2 laser light wavelength and exclude people and animals from the room being used.  

As CO2 laser radiation is completely invisible and is being bounced around inside the laser cabinet, the potential for extremely painful burns to hands and fingers remains whenever the lid is not closed when the laser is operating.

Your laser room should also be protected with suitable Laser Safety warnings for others.  Ensure that appropriate warning signs are visible and especially for diode lasers, make sure that there are laser safety goggles available before someone enters the room.  

When used with the appropriate safety precautions, Laser cutters are safe and are considered Class 1 - safe for operators and bystanders. Operating them carelessly and without regard to the inherent dangers that exist will potentially cause life-changing injury.  

Avoid Electrical Laser Safety Hazards  

The CO2 laser cutter works with extremely high voltages, some in excess of 25,000 volts, and these voltages are lethal. These high-voltage areas are protected by cabinet doors and these must remain closed whenever the laser is switched on. An emergency stop button is provided to immediately isolate any voltages but if you plan on working inside the electronics cabinet, it is highly recommended that you disconnect the laser from the mains.  

One of the main potential problems with the high voltage system is when the laser is located where it is subject to a build up of condensation. This can cause the wiring and connectors to arc and short out. Always remember to check the laser cutter for any signs of condensation before you start using it and ensure that the room is suitably conditioned (heating, ventilation) to prevent condensation from forming. An arcing high voltage system will produce a snapping sound when the laser is operating. Switch off the laser immediately before isolating and resolving the problem.

Safety Precautions for Flames and Burning  

Can a CO2 laser engraver catch fire?

Depending on the flammability of your workpiece, it is possible for your laser engraver to catch fire. Your CO2 laser fires its focused laser beam onto the workpiece which then vaporizes the material. At low power or high speed, this can just engrave the surface, or with some materials, a higher power or slower speed will actually cut through it. On flammable materials such as wood, cardboard, etc, the edges of the cut may burn rather than vaporize.

That's why the laser engraver is fitted with an air pump that prevents the material from igniting. Normally, the airflow through the nozzle is sufficient to ensure that the flame does not take hold. But if the air pump fails or a pipe becomes disconnected, then the workpiece could catch fire. This is why it is essential to ensure that the air pump is working and that all the pipework is secure. A failure of the air pump or pipework can lead to the material being cut or engraved igniting and a fire may ensue.

One other reason that can lead to a potential fire is if the X or Y axis become jammed such that the laser continues to burn the same point repeatedly. This is a good reason to ensure that you undertake regular maintenance of the laser cutter including cleaning, lubrication, and checking the toothed belts, and keeping the work bed clear of debris, old projects, or anything other than the piece being engraved.

This is one of the primary reasons why you must NEVER leave your laser cutter unattended while in use.

How do you extinguish a laser engraver fire?

If your laser engraver ever catches fire, you can extinguish it by using the emergency stop to disable the laser machine and then quickly cover the machine with a fire blanket to extinguish the fire. Use a fire extinguisher if necessary, and never use a fire extinguisher on a working laser due to the extremely high voltages. Wait for everything to cool down before examining it for the cause and damage.

Safety precautions for mechanical problems 

The laser cutter uses several powerful servo motors that move the laser head to engrave or cut the design. Apart from sensors that detect the ends of travel, these motors cannot detect if anything gets jammed. Given the extreme force that they can apply, putting your hands and fingers inside the laser cabinet when it is switched on is extremely dangerous and can cause significant injury. Keep any other items outside of the cabinet, such as tools, additional workpieces and always keep the cabinet doors closed when the laser is switched on.  

Laser Engraver Exhaust: Safe Ventilation 

Are fumes from laser cutting toxic?

Yes, laser cutter fumes and even the smoke produced by CO₂ laser engravers can be toxic to your health. Even laser engraving and cutting the basic materials like wood and acrylic produces noxious fumes and carbon monoxide. However, most laser engravers are equipped with ventilation systems that remove the fumes to the outdoors where they will quickly dissipate. As long as your ventilation system is set up correctly, any laser cutting odors you might experience do not contain any airborne toxins.

Is laser cutting acrylic toxic?

Yes, laser cutting acrylic can produce toxic fumes. When acrylic is cut with a laser, it can release harmful gases such as formaldehyde, hydrogen cyanide, and other volatile organic compounds (VOCs). These fumes can be irritating to the eyes, nose, and throat, and can cause respiratory problems.

It is important to work in a well-ventilated area when laser cutting acrylic. You should also wear a respirator mask to protect yourself from inhaling toxic fumes. Additionally, it is recommended to use a smoke extractor to remove the fumes from the workspace.

Should you wear a mask when laser engraving?

While wearing a mask is generally recommended for laser engraving due to potential exposure to fumes and particulate matter, it may not be strictly necessary in all cases. Machines like those manufactured by OMTech often feature enclosed designs and advanced ventilation systems. These systems are designed to efficiently remove fumes and dust from the workspace, ensuring a clean and safe working environment.

If you want to learn more, please visit our website home laser cutter machine.

However, it's important to note that frequent interruptions or extended operation can compromise the effectiveness of these ventilation systems. If you find yourself frequently opening the machine to retrieve materials or if the machine operates for prolonged periods, you may be exposed to residual fumes. In these scenarios, wearing a respirator mask is highly recommended to protect your respiratory health.

How harmful is laser dust?

Laser dust and smoke are considered to be PM2.5 which means that inhaling them should be avoided. As long as the ventilation system is working efficiently, most of these particles should disperse harmlessly outside and alleviate any laser cutting health concerns.

Can you use a laser engraver indoors?

You can use a laser engraving machine indoors if you have a proper ventilation system in place. Whatever material is being laser cut or engraved will produce smoke and fumes and these must be removed quickly and safely from the laser cabinet. Excessive laser cutter fumes and smoke can condense onto the laser mechanisms causing premature bearing failure and damage to the focal lens and laser mirrors.

While laser engraving at home indoors is possible, it is preferable to use a climate-controlled garage, shed, or other outbuilding. The main issue will be the smell of the material being engraved. Although a good ventilation system will remove almost all of the laser cutter fumes and smoke from the laser cabinet, it is not airtight and some smell will still be noticeable.

How do you vent a home laser engraver?

Your CO₂ laser engraver should come with a ventilation fan near the exhaust port and a flexible ducting hose. Upon initial machine setup, you should connect one side of the ducting to the laser machine’s exhaust port, and the other to a safe exit vent that releases the exhaust to the outdoors. The ventilation fan should be strong enough to push the laser cutting fumes and other airborne debris through the ducting and out your exit vent. However, if you have a large laser cutting workload, you may need to add an inline fan to help suck the exhaust out faster. Always ensure your ventilation fan is switched on before starting the laser. After completion, leave it running for a minute or so to fully ventilate the cabinet and remove all the laser cutter fumes. 

The outlet from the fan should exit outside of the building, either through a dedicated outlet or a window and be suitably protected from wind and animal/insect intrusion with a mesh and air flap. Ensure that it is kept away from anywhere where people may pass too closely or congregate. The smell of laser cutter fumes and smoke residue will be noticeable and so be careful not to cause problems with neighbors. Remember that you are responsible for meeting all applicable local and national laws and regulations regarding the ventilation of laser cutter fumes and smoke from your laser.

Pro Tip: For greater efficiency, if you have a long run of ventilation pipework, place the ventilation fan close to the outlet so that the fan pulls air through the longer pipework, rather than pushing it.

Laser Cutter Materials Safety

Your laser cutter can cut and engrave many materials but there are some that you must avoid. If in doubt, look for the MSDS Safety Sheet for that material. As the laser burns and vaporizes it, the Safety Sheet will inform you of any dangerous byproducts released during combustion.

Materials that can be laser engraved and cut: 

• Cardboard
• Ceramics, including Dishes, Tile, etc.
• Glass
• Paper & Paperboard
• Rubber
• Genuine Leather*
• Stone, including Marble, Granite, River Rock, etc.
• Textiles, including Cotton, Suede, Felt, Hemp, etc.
• Wood, including Cork, MDF, Plywood, Balsa, Birch, Cherry, Oak, Poplar, etc.
• Plastics including:
• Nylon (Polyamide, PA, etc.)
• Polyethylene (PE)
• High-Density Polyethylene (HDPE, PEHD, etc.)
• Biaxially-Oriented Polyethylene Terephthalate (BoPET, Mylar, Polyester, etc.)
• Polyethylene Terephthalate Glycol (PETG, PET-G, etc.)
• Polyimide (PI, Kapton, etc.)
• Polymethyl Methacrylate (PMMA, Acrylic, Plexiglass, Lucite, etc.)
• Polyoxymethylene (POM, Acetal, Delrin, etc.)
• Polypropylene (PP, etc.)
• Styrene

*Genuine leather can be safely laser cut or engraved, but ensure that if it has been tanned then it is “veg-tanned” otherwise it will have been treated with chromium salts that will release dangerous particles when laser engraved.

Materials that cannot be laser cut or engraved:

• Artificial Leather containing Hexavalent Chromium (Cr[VI])
• Chlorine, including Polyvinyl Butyrale (PVB) and Polyvinyl Chloride (PVC, Vinyl, Cintra, etc.)
• Fluorine, including Polytetrafluoroethylenes (Teflon, PTFE, etc.)
• Materials with Halocarbon compounds
• Phenolic Resins, including various forms of Epoxy
• Polycarbonate (PC, Lexan, etc.)

Of particular note is anything made from PVC or Vinyl. Not only are the fumes toxic, but they will also condense inside the laser cabinet and cause rapid and premature corrosion of metal surfaces, bearings, etc.

You can mark metals with a CO₂ laser with the help of a special coating agent. However, you cannot cut or engrave metals with a standard CO2 Laser due to their conductivity and reflectivity. If you want to engrave metal then have a look at the OMTech Fiber Laser range.

Best Diode Laser Engraver

Diode lasers have made significant advancements in recent years. Just two years ago, they were seen as weak hobby tools with only 5 watts of output power. Today however, diode laser engravers are powerful and mature machines, capable of cutting and engraving at high speeds.

The best diode laser engraver I tested in was the Sculpfun SF-A9 [Official store, Geekbuying, Aliexpress, TomTop, Amazon] (read the full review). It features a 40-watt octa-diode laser module mounted on a very solid and sturdy mechanical gantry, allowing for high-speed, precise engraving. The laser module has two selectable power output ranges, and the motor controller offers two acceleration and speed modes, letting you choose between precision and accuracy or power and speed. You can also buy an infrared laser module addon, which is ideal for engraving metal and plastics, making this a very versatile machine, capable of engraving a lot of different materials.

If you are looking for a cheaper option, you should also check out other engravers from Sculpfun. I have tested a ton of various diode engravers and Sculpfun machines were always amongst the best performing in its class.

But if you’re looking for an enclosed diode engraver, you should check out the xTool S1 enclosed laser engraver (read the full review) which was the last year’s winner which still remains one of the best options today. It offers a variety of laser modules and accessories, making it a great choice for many applications.

Best Fiber Laser Engraver

Fiber lasers are becoming more affordable and powerful every day. This year, I have tested many MOPA fiber lasers, which are the best version of fiber lasers because they offer significantly more adjustability, allowing you to create various engraving effects on both plastics and metals. MOPA fiber lasers are ideal for creating deep engravings on all types of metal, instantly ablating the surface to produce deep 3D engravings, and they can also be used for cutting thin sheets of metal.

These lasers excel at rust removal on delicate parts and can engrave leather and some plastics as well. MOPA fiber lasers are particularly effective for creating colored engravings on stainless steel and titanium and producing various shades of gray on anodized aluminum. They are also capable of making impressively deep engravings in stone.

The ComMarker B4 [Official store, Amazon, Aliexpress] is a simple and straightforward fiber laser with a tall column and great versatility, as it comes with two lenses and a foot switch as standard (read full review). I also tested the new ComMarker B6, which offers the same power in a smaller frame and can be used in a split configuration. Its main improvement is the autofocus function, which the B4 lacks. ComMarker machines are excellent because they offer a wide range of accessories, such as different types of rotary attachments, workbenches, enclosures, and fixtures, allowing you to customize them for your specific needs. (read the full review of the B6). Both the ComMarker B4 and the B6 are ideal for small engraving businesses.

The big surprise this year was the Monport GA60 [US store, DE store, UK store, Amazon store], which also has a good autofocus system and features a very sturdy, adjustable vertical column that can rotate and can also be easily collapsed for storage (read the full review). The machine is very sturdy and comes well calibrated out of the box. The Monport GA60 is very convenient to use and produces great results.

So, which is the best fiber laser engraver in ? The answer depends on which one best suits your work. While they offer similar engraving performance, the accessories and features can make one machine a better choice over another, depending on your needs. You should check out our full reviews of each of them and see which one will suit you best.

The only downside to fiber lasers is that they cannot engrave wood or similar materials.

Best CO2 Laser Cutter

So far this year I have tested only one CO2 laser – the Atomstack Hurricane. It is a 55-watt desktop laser which proved itself to be a very good laser cutter in its price range (read the full review). It produces incredibly good engravings with high contrast and performs very well at laser cutting.

Although compared to last year’s winner – the xTool P2, it falls behind when cutting thicker materials and also lacks the advanced dual camera positioning system that ensures incredible positioning accuracy, and misses a wider range of advanced features like the curved surface engraving (read the full review of the xTool P2).

Other than that, the Hurricane is a very solid machine that works very well and can be a good choice if you don’t need all those features. But I have to say I was impressed with the conveyor feeder tray which expands the working area.

But this year, xTool has upgraded the P2 into the xTool P2S which features stronger air assist, better optical path and improved engraving speeds. I haven’t tested the P2S yet, but it is on its way, and I will test it very soon, to see how well it performs with all those upgrades. Subscribe to our mailing list and get notified when we test it! You can use my discount code “xToolJT” for additional discount at checkout!

Best Dual-Beam Laser Engraver

If you like galvo-style lasers but want the ability to engrave more materials, the xTool F1 Ultra is the ideal choice for you. It is the larger, upgraded version of the older xTool F1 (review here) and features both a 20-watt blue diode laser and a 20-watt true fiber laser in a compact design (read the full review of the xTool F1 Ultra).

The blue diode laser module is perfect for cutting and engraving wood, leather, plastic and other organic materials. And the infrared fiber laser is great for marking raw aluminum, brass, copper, zinc, chrome coatings, plastics and similar materials.

As a result, the xTool F1 Ultra is just as effective at engraving wood as it is at engraving metals and plastic. Its powerful 20-watt blue diode laser also makes it excellent for laser cutting. The dual-beam setup allows you to engrave a very wide range of materials—something that is impossible to do with a single laser module.

Additionally, it enables you to use both laser beams in the same engraving project. A cool thing I like to do is to engrave a photo on black acrylic using fiber laser which produces crisp white engravings, and then make a cutout using a blue laser module which makes a clean cut.  This combination allows for unique results that would be impossible with only one laser module. This makes the xTool F1 Ultra one of the best galvo laser engravers.

The infrared laser can also make deep 3D engravings in metals which is an easy way to make a valuable customized gift.

Best UV Laser For Engraving (almost) Any Kind of Material

So far we have learned that each laser type has its own limitations in terms of materials they can engrave.

For a rough example, diode lasers work great on wood, but can’t engrave metals other than stainless steel and they can’t cut white or transparent materials. Fiber lasers can make wonders on all types of metals, but they can’t engrave wood and aren’t the best for some plastics. CO2 laser is the best for working with wood and cutting plastics, but they can’t mark metals directly.

If you’re looking for a single machine that performs well on wood, plastics, metals and glass, a UV laser is your answer. But the problem with these machines is that they are usually very expensive, and they require an external water chiller too.

But this year, ComMarker has released one of the most affordable UV lasers with a solid power output. The ComMarker Omni 1 is a compact 5-watt air cooled galvo UV laser engraver (read the full review).

But don’t think that it is a weak machine for having just 5 watts of power. UV light is very well absorbed by a wide range of materials, meaning a UV laser can engrave almost anything, including metals, plastics, leather, wood, stone and—most importantly—glass.

It produces incredibly detailed engravings on glass, even better than sandblasting. It is the only type of laser that can ablate glass directly which means it can also cut it very well. And it can do all that at a very high speed!

UV laser is also the best type of laser for engraving plastics. While other types of lasers can also engrave plastics, but they produce limiting results with low contrast by just melting the surface. In contrast, UV lasers create sharp, high-contrast engravings on nearly all plastic types.

Plus, the UV laser beam generates very little heat, which prevents thin metals or plastics from melting and bending and leaves no smoke stains on wood—a feature unique to UV lasers which work by directly breaking chemical bonds in the material. And since the UV light has very short wavelength, the laser spot size of the UV laser is the smallest of any other laser, which makes it possible to engrave incredibly small text. The example below is 0.5mm tall text engraved on a regular toothpick.

The ComMarker Omni 1 is an excellent choice if you want a simple, versatile device that can handle almost everything. It is one of the best affordable UV laser engravers on the market today.

If you want to learn the practical differences between UV and Fiber lasers, you can check our new article, where I tested both types of lasers on the same materials to see which one is the best for each material.

Best Accessory For ANY Laser!

Currently I am testing the most important accessory for any laser – the xTool SafetyPro AP2 Air Purifier with SuperCyclone System. This is a revolutionary 5-stage cyclone air purification system that is used for removing toxic fumes and smell that is generated while laser engraving with any type of laser. It is a great investment in your health and the health of those around you.

I will soon make a full review article to test it more thoroughly, Subscribe to our mailing list and get notified when the article will be released!
