The size of your workshop
Laser cutters tend to be large, so make sure you measure your space first.
What materials you want to cut
Diodes have trouble cutting into clear materials, and CO2 struggles with metal. Choose the right one for the materials you want to work with.
Laser cutters produce smoke and dust, so proper ventilation is essential. If you don't have access to a window, think about getting a powerful air purifier system.
There are many ways to make your artistic creations come to life. I love using the best 3D printers to create art, but I also enjoy using laser cutters -- sometimes called laser etchers or laser engravers -- to work with other materials. Etching designs onto glass and leather, or cutting through wood and acrylic, can create objects that are simply stunning.
Being creative has never been easier than it is right now. More and more people are identifying as makers, people with a desire to create, and entire industries have sprung up around homemade creations. Machines like 3D printers, vinyl cutters and laser cutters are now available at prices to fit just about any pocketbook. They allow people to bring their creations to life in new and interesting ways. You can even turn a profit on stores like Etsy and Shopify if you have the right materials and machines.
I've used laser cutters for about five years to create a variety of projects, from small dog tags to etching a 7-foot workbench with elven runes. Each cutter I use has a host of different pros and cons, so along with my CNET colleague Russell Holly, I've developed testing criteria to assess the best laser cutters around.
The xTool P2 is our top pick for the best laser cutter. It isn't the cheapest laser cutter around, but with a host of amazing accessories, fantastic software and a cutting size and speed that are hard to ignore, it takes the crown from the Glowforge Pro, but just barely. It is huge though, so make sure you have room in your workshop to house it.
The Xtool P2 is the complete package for fast, powerful laser cutting at home or in a small workshop. With a full suite of accessories that let you cut 3-meter-long materials and round tumblers and glasses, the P2 can cut or etch any material you could hope for, including glass and transparent acrylic.
The software is excellent and can help you design your creations to better fit your cutting needs. The camera works well to help you align your materials, but be careful when working near the edge of the camera limits, because the fisheye distorts a little. This bundle comes with some materials to get you started and a fire safety system to give you peace of mind.

The Glowforge Aura is the company's first consumer laser cutter aimed at the entry-level market. It's smaller than the other models, with a less powerful laser, but it works amazingly well on smaller projects. We've made beautiful carvings, etchings and other laser-cut projects on the aura, and all of them have been excellent.

The Beamo is the smallest of Flux's impressive lineup of CO2 laser cutters, but don't let the small size fool you. The 30-watt laser, while weaker than some on this list, is still powerful enough to etch glass, though you may need the additional diode laser to etch onto steel. It will happily cut through wood, leather and acrylic though.
The Beamo also comes with a handy touchscreen on the device, making it much easier to control from your workshop without a computer plugged into it directly. Flux even has an app that'll let you control the Beamo directly from your phone.
Diode lasers are often low-powered, with no enclosure to keep you safe. The S1 solves both those problems by having a 40-watt laser that can cut through 18mm of wood in a single, albeit slow, pass. It also has a fantastic enclosure with a green lid to filter the laser's light and an active exhaust to blow away any smoke. The basic kit has air assist -- something all lasers should have -- and a honeycomb cutting surface to help reduce scorching on the underside of your material.
The S1 doesn't have a camera -- I think it should -- so everything is handled very manually. But that's true for most diode lasers.
Glowforge has made it clear its mission from the start has been to ensure anyone can use what it calls "laser printers," and the Glowforge Pro is a shining example. A fisheye camera gives you a view of the cutting surface from a web app, which lets you effortlessly click and drag the things you want to engrave or cut. And if you pay for the extra filtration system, you can use this laser anywhere. Of all the systems tested here, the Glowforge's focus on ease of use is a world apart.
With that ease of use comes some limitations you won't find elsewhere. Many features that make the Glowforge Pro great are available only if you pay a monthly subscription. If you're not using the Glowforge-made Proofgrade, the process of identifying the correct settings for engraving or cutting becomes quite manual. Additionally, the fisheye lens that Glowforge uses can occasionally cause accuracy issues when you're cutting or engraving on small, perfectly centered surfaces.
You've got questions and we've got answers. We hope!
It will depend on what you want out of your laser. If you're looking to etch onto wood, leather or anodized aluminum, then a diode laser is cheaper, and it's easier to look after than a CO2 machine. Diode lasers, especially the cheaper ones, can be harder to set up than CO2, though, and will be slower. If you want rapid etching and a more powerful cutting experience, then opt for a CO2 laser.
Laser cutters can range from $500, for a cheap, DIY laser option, all the way up to $5,000 and beyond, for a big Glowforge. I'd recommend looking to start your laser-cutting journey somewhere around the $1,000 mark for a diode, or $2,000 for a CO2.
Most lasers, CO2 or Diode, can cut wood, acrylic and leather up to around 5mm thick. The more powerful the laser, the thicker it'll cut. Etching is easier and can be done by just about any laser, though metal etching works better with a diode, and glass and clear acrylic is better with a CO2 laser. A shortlist of materials can include:
Anything that gives off toxic gasses should be avoided, though if you have a good filtration system, a lot of that can be mitigated. You shouldn't cut anything likely to melt instead of fuse cleanly.
Testing laser cutters is a mix of objective and subjective measures. We spend time measuring speed and accuracy as well as usability and the overall look of the finished product. These tests are done in our labs and workshops over a month to ensure the lasers can endure proper use.
How do these laser cutters match up
Speed is tested with a good old-fashioned stopwatch. I created a simple CNET logo design that can be cut on multiple materials. We time how long it takes to complete the cut. We use 3mm basswood, 3mm black acrylic and 3.5mm cardboard for our testing materials, to give us a good overall view. We then compare the speed with the software to see how accurately it calculates the cutting speeds.
Engraving is done with an image of my beautiful dog Indiana Bones. I import that image into the workspace and use 3mm basswood for the material. I use the standard engraving settings from each machine to engrave Indy onto the wood. My CNET colleague Russell Holly and I then examine the etching for image quality. We're looking at contrast, the level of detail captured, and how grainy the image is, as well as considering our opinion on the overall quality.
Indiana is the perfect test subject for laser engraving.
Cnc Fiber Laser Cutter For laser cutters with cameras, I created an accuracy test. I designed a file with 10mm and 5mm increments. The file is printed on standard paper and imported into the laser cutter software. From there, we use the laser cutter camera to align the physical marks to the digital and set the laser to cut. Once the laser is finished, we measure the offset using a micrometer to see how accurately the camera represented the paper image. This is especially helpful for laser cutters with fisheye lenses.
