Best Laser Engraving Machines

Whether you’re looking to personalize prized possessions, add a unique design feature to your products, or level up your workshop, a laser engraving machine will help you achieve your goal. Allowing designers, hobbyists, and business owners to add a truly bespoke addition to their crafts, all from the comfort of your own home. 

By utilizing a high-powered laser, these machines can engrave intricate detail with pinpoint precision. They are extremely easy to use, simply upload your chosen design and the operating system will map the route of the laser. This is a subtractive manufacturing technology, meaning the laser will then melt and vaporize the specific design and thickness desired into your chosen material.

Choosing the right laser engraver for your needs is no easy decision, however. As these machines aren’t cheap, it’s important to assess the following factors before taking the plunge:

  • Cutting plate size – determining the surface area the laser can reach.
  • Materials you would like to engrave on – from wood to leather to steel, different laser engravers are capable of working with a variety of materials.
  • Space – ensuring you have the room and adequate ventilation for your chosen machine.

If you’re just dipping your toe into the world of engraving or you are an experienced craftsperson looking to elevate your designs to the next level, we’ve put together our favorite laser engraving machines to help you decide. 

When putting together our top picks, we made sure to include a range of machines to suit different budgets, expertise, and product needs. We also analyzed genuine customer reviews to ensure real customers like you were satisfied with their laser engraver.

beamo 30W Desktop Laser Cutter & Engraver

This is a very powerful laser engraver with the smallest footprint available on the market today. It is an entry-level laser cutter that delivers professional quality work and is suitable for your home, office, classroom, or design studio. You can even use it in your car or van. With the Smart Trace software, drawings are changed to digital files, and you can engrave your drawings onto hundreds of objects. 

Smart Trace is a great feature for businesses that want to cut their logo onto objects that they give as gifts such as mugs or keychains for marketing. The technology allows you to choose the graphics editor for JPG, SVG, PNG, and DXF file formats. If you buy the rotary, it will etch glasses and bottles. A colorful LCD touchscreen on the top of the unit has an on/off switch and settings that make it easy even for a child to set up.

You can even take pictures with your phone and upload them to the printer. Just align the design and your printer will do the job. It is compatible with Adobe Illustrator, Inscape, Autocad, Silhouette Studio and CorelDraw, Microsoft Word, and PowerPoint. The dimensions are 24 x 20 x 10 inches and the weight is 49 pounds. 

This machine is comparatively lightweight at 50 pounds which is much less than most bulky printers. The ventilation fan helps prevent fires and extracts smoke and fumes, and it includes several other safety features.


  • The laser engraves with an incredibly thin 0.05 layer spacing that is thinner than a human hair
  • It has a high 1,000 DPI resolution
  • Closed-loop liquid cooling system

2. Compact Laser Engraver

Compact Laser Engraver Machine, LaserPecker Mini Desktop Laser Engraving Portable Laser Etcher Laser Cutter Printer with Safety Glasses for DIY Logo Design, Art Craft Science Gold

This is a portable, lightweight laser engraver that can be taken anywhere because it is powered by a power bank. First, you connect with the LaserPecker app and choose or upload any pattern in-app and personalize it. It has a preview mode that shows a square on the surface of whatever you are engraving, so you can adjust the position and size of the image to be engraved. You can text any pictures, patterns, logos, or other designs to the LaserPecker app and modify the images before engraving. It is compatible with JPG, PNG, BMP, photos, and vectors.

You can engrave horizontally or vertically. Horizontally means the laser sits on the power bank with the laser pointing at the object you want to be engraved. You may have a decorative pillow you want to put a particular design on or a leather jacket you want to put an emblem on. Just set them up vertically, and point the laser at the spot you want to be engraved. For vertical engraving, you need a small tripod. Put the piece of fruit, glass coaster, wallet, or whatever under the unit and adjust to the area you want to be engraved, and the laser will point straight down. 

This small, portable laser is suitable for designers, craft enthusiasts, restaurant owners, companies that need free marketing perks such as keychains or pens, and other artists or handcrafters. It works on wood, colored paper, leather, felt, or even fruit. The unit’s dimensions are 2.09 x 2.4 x 2.56 inches.

FAQs about Laser Engraving Machines 300

How does Laser engraving work?

A laser engraver is very much like printing. First, you create the design that you want to engrave. This may be a hand-drawn picture that you scan or something chosen from a graphics program such as CoralDraw or AutoCAD. The graphic is sent to the laser through the printer driver. 

When you start the work, the laser cuts or engraves the material you have placed on the board. Advanced settings such as JobControl laser software store the graphics in the printer driver and automatically optimize the process. This makes it easy if you use the machine every day.

How do Lasers operate?

The lasers used in engraving machines have an extremely narrow beam of light in which all the light waves have almost the same wavelengths. When the machine makes them travel together, the light beam peaks all line-up, making the light beam very narrow and bright. 

The optics inside the machine focus this light into a minuscule spot usually no bigger than a single human hair. Depending on the type of material being cut or engraved, this intense spot of light will burn, melt or vaporize the material leaving behind a sharp and smooth surface finish.

What materials are unsuitable for laser cutting and engraving?

Some materials are dangerous to cut or engrave with a laser machine. The most commonly available materials that you should not cut are:

  • PVC (Polyvinyl chloride) includes vinyl, pleather, and other artificial leathers. The danger is it emits pure chlorine gas when it is cut
  • Acrylonitrile butadiene styrene (ABS) is a tough lightweight plastic that is often used for car parts and countertops. The danger is it will emit cyanide gas, and it tends to melt
  • Thick (>1mm) Polycarbonate/Lexan. The reason is it doesn’t cut well, discolors, and catches fire
  • HDPE or milk bottle plastic will melt and catch fire
  • Any material that contains halogens such as chlorine, fluorine, iodine, bromine, and astatine as well as phenolic or epoxy resins

Which Laser Engraving Machine is Best for You?

Among the many ways to engrave materials, a laser is the most efficient, reliable, and cost-effective. It delivers very high-quality results for small or huge projects. Major industries use different kinds of laser engraving machines, but even for crafting and artistic design at home, school or office there are several different types of smaller machines that are shown above.

Laser engraving is also very environmentally friendly. It doesn’t require toxic chemicals, which makes it safer for children accompanied by an adult to use. After the work is done, it leaves very little, if any, waste behind because the material is vaporized. Any waste is usually in the form of particle dust that is harmless. 

With laser engraving or cutting, there is no contact with the material being cut. The heat does the work, and the product is not damaged by the abrasion that happens with other engraving methods. Remember, this is a Class 4 machine that should be kept out of the reach of young children and any user should always wear goggles.
