I’ve set up enough laser machines to know what changes the first time you run a CO2. The cuts are cleaner. The material list is longer. You stop fighting the physics of a diode beam trying to engrave glass or slice through thick acrylic in a single pass.
CO2 laser engravers use a completely different light source than diode machines, and that difference shows up immediately in what you can make, how fast, and the quality you get.
If you’re searching for the best CO2 laser engravers specifically, you already know you’ve outgrown diode — or you’re starting with the right tool for the job. This guide covers the five best CO2 laser engravers right now, organized by budget tier, with honest notes on who each machine is actually built for.
What Is a CO2 Laser Engraver?
A CO2 laser engraver uses a carbon dioxide gas-filled tube to produce a 10,600nm infrared beam. That wavelength is absorbed efficiently by non-metals, which is why CO2 machines cut and engrave wood, acrylic, glass, leather, and fabric far better than diode laser engravers. It’s the standard technology in professional laser cutting for a reason.
Diode lasers produce a visible blue beam (around 450nm) that struggles with transparent and light-colored materials. CO2 doesn’t have that limitation. Clear acrylic, frosted glass, light-toned leather — CO2 handles all of it without surface prep or workarounds.
The trade-offs are real. CO2 machines cost more, take up more space, require proper ventilation, and can’t cut bare sheet metal (that’s fiber laser territory). But for wood, acrylic, and organic materials, nothing in the same price range touches them.
If you’re still deciding between laser types, our guide to the best laser engravers for beginners covers the full breakdown.
1. xTool P2S: Best Desktop CO2 Laser Engraver
For most home and small business users, yes. The xTool P2S packs a 55W CO2 laser, dual 16MP cameras with LiDAR autofocus, and a 26″×14″ enclosed work area into a desktop footprint. It cuts through all colors of acrylic up to 20mm thick and handles wood up to 18mm in a single pass. It runs LightBurn natively.
The camera system is what separates it from most machines in this class.
According to xTool, the LiDAR Ranging System autofocuses to 0.001″ precision and automatically constructs 3D models of curved objects, adjusting focal length throughout the job. That matters when you’re engraving cylindrical items like cups or bottles, where most machines need manual adjustments mid-run.
Auto-Passthrough supports materials up to 118″ long — useful for long boards or custom signage. The fully enclosed design is Class 1 rated, which makes it viable for home studio use without an industrial setup.
Engraving tops out at 600mm/s. Plenty for most production schedules, though you’ll notice the difference if you’re running high-volume batch jobs.
The P2S is an investment, but for anyone running a craft or custom goods business, it earns its price.

2. Gweike Cloud Pro II: Best Value CO2 Laser Engraver
The Gweike Cloud Pro II gets you into 55W CO2 territory at a lower price than the xTool P2S. The trade-offs are real but manageable: the work area is 20″×12″ (vs the P2S’s 26″×14″), and the built-in camera is 5MP instead of 16MP.
What you don’t lose: engraving speed (also 600mm/s), precision (0.001″), or LightBurn compatibility. The closed-loop liquid cooling with built-in heat exchanger keeps the CO2 tube running efficiently.
The fully enclosed design qualifies it as Class 1, making it safe for studio and home use.
One caveat worth knowing before you buy:
The Wi-Fi/LightBurn camera integration can be buggy. Several users have reported needing a direct USB connection to get the camera working consistently. It’s not a dealbreaker, but factor it into your setup expectations.
For buyers who don’t need the largest bed or the most advanced camera, the Gweike Cloud Pro II is hard to beat on value.
3. OMTech K40+: Best Budget CO2 Laser Engraver
The OMTech K40+ is the classic entry point into CO2 laser engraving, and this upgraded version is the best it’s ever been. The 45W CO2 tube, 8″×12″ work area, and LightBurn/LaserGRBL compatibility come standard. Air assist and water pump are included.
OMTech rates it for cutting through 0.4″ acrylic and 0.31″ wood.
The 8″×12″ bed is the real limitation.
You’ll hit it faster than you expect — especially once you start taking on larger projects. But for learning CO2, running small product batches, or doing personalized gifts and signage, it’s more than enough machine.
The 45W tube won’t match the output of a 55W machine. Cuts are a little slower, and you’ll need multiple passes on thicker material. But it’s a real CO2 laser at a fraction of the price of the machines above it.
Who it’s for: first-time CO2 buyers, hobbyists, and anyone who wants to learn the technology before committing to a bigger investment.
4. iKier Master
If you want a CO2 machine that sits between the entry-level OMTech K40+ and the premium xTool P2S, the iKier Master fills that gap cleanly. Its 50W CO2 core handles 13mm wood and 18mm acrylic. It supports both CO2 and IR lasers on the same platform, so you can switch between material types without a second machine. The touchscreen and LightBurn compatibility make it intuitive to run from day one.
The dual laser capability is the real differentiator.
Most CO2 machines at this price point are single-laser-only. Being able to switch between CO2 (excellent for non-metals and organic materials) and IR (better for certain coated metals and specific applications) gives you a wider material range without doubling your equipment budget.
iKier is a sub-brand of Atomstack, which means solid support infrastructure and an active maker community. The Master platform also supports rotary attachments and extended beds, so there’s room to expand as your work grows.
Who it’s for: makers who want production-ready capability, dual laser flexibility, and a clear upgrade path — without going full commercial.
5. xTool P3: Best Professional CO2 Laser Engraver
The xTool P3 is what you buy when you’ve outgrown the P2S and need production capacity. The 80W industrial-grade CO2 laser runs at 1200mm/s — twice the speed of most desktop CO2 machines.
The work area jumps to 36″×18″, and there’s a built-in active fire suppression system, which matters at this power level.
The quad-camera setup and Smart RA3 Rotary accessory (with 360° LiDAR mapping for batch cylindrical engraving) push this into a different category from the machines above. Processing depth reaches 8.66″, which handles larger 3D objects most desktop machines can’t accommodate.
It’s Class 1, LightBurn compatible, and engineered for commercial throughput. The price reflects that.
Who it’s for: small businesses running high-volume production, professionals where laser output is a core revenue driver, and anyone who’s maxed out a P2S and needs more.
How to Choose a CO2 Laser Engraver
Start with three things: power, bed size, and enclosure. Power of 40–55W handles the vast majority of hobbyist and small business work. A 55W enclosed machine is the sweet spot for most buyers. Go to 80W only if you’re running production volume and billing for it.
Bed size scales with your projects. An 8″×12″ bed is fine for small goods and jewelry. A 20″×12″ handles mid-size signage and product runs. The 26″×14″ and larger beds are for serious makers and commercial use. Don’t underestimate how quickly a small bed becomes the bottleneck when your project scope grows.
Enclosure matters more with CO2 than diode. Open-frame CO2 machines require you to build or buy an external enclosure, which adds cost and setup complexity. For home and studio use, fully enclosed machines are the cleaner, safer choice.
Software is the last check. LightBurn is the industry standard for CO2 laser engravers, and every machine in this guide supports it. If a machine you’re considering doesn’t have confirmed LightBurn compatibility, that’s a red flag worth investigating before you buy.
For material-specific picks, our guides to laser engravers for wood and laser engravers for metal cover the nuances in more depth.
Do CO2 Laser Engravers Require Special Ventilation?
Yes, and this is one of the most overlooked considerations when buying a CO2 engraver. Every machine produces smoke and fumes when cutting or engraving materials. Some of those fumes are toxic — PVC and chlorine-containing vinyl are the worst offenders. Never run those through a laser engraver, ever.
For safe materials like wood, acrylic, leather, and fabric, the fumes are manageable but still need to go somewhere. Enclosed machines include a built-in exhaust port. You’ll need to duct it outside (the simplest option), or use a laser-rated air filtration system with HEPA and activated carbon filters.
This isn’t optional. Proper ventilation protects your health and your machine’s optics. Budget for a filtration solution before you buy the machine — not as an afterthought.

Frequently Asked Questions
What’s the difference between a CO2 laser engraver and a diode laser engraver?
CO2 laser engravers use a gas-filled tube to produce a 10,600nm infrared beam, which cuts and engraves wood, acrylic, glass, fabric, and leather efficiently. Diode laser engravers use semiconductor technology and produce a visible blue beam (around 450nm) that struggles with transparent or light-colored materials. CO2 machines handle more materials and cut faster, but they cost more and require proper ventilation.
Can CO2 laser engravers cut metal?
CO2 lasers can engrave coated metals and mark bare metals with a laser marking spray, but they can’t cut bare sheet metal. For cutting through metal, you need a fiber laser. CO2 machines are well suited to everything else: wood, acrylic, glass, fabric, leather, rubber, and stone.
How long does a CO2 laser tube last?
A quality CO2 glass laser tube typically lasts between 2,000 and 10,000 hours of use, depending on brand and power level. The Gweike Cloud Pro II rates its tube at up to 10,000 hours, for reference. Power output gradually drops before the tube fails entirely, so you’ll usually have warning time before needing a replacement.
Is LightBurn compatible with all CO2 laser engravers?
Most quality CO2 laser engravers support LightBurn, but it’s not universal. Every machine in this guide is LightBurn compatible. Budget or no-brand machines sometimes only support older software like LaserGRBL or proprietary programs. LightBurn requires a one-time license purchase and offers a 30-day free trial.
What materials can a CO2 laser engraver work with?
CO2 laser engravers work well on wood, plywood, MDF, acrylic (all colors), glass, leather, fabric, rubber, stone, and coated metals. Materials to avoid include PVC, vinyl containing chlorine, and polycarbonate — these produce toxic fumes when burned. Always verify material safety before processing anything unfamiliar through your machine.
