Cut acrylic and sheet materials
Clear and colored acrylic needs a CO2 laser. A diode generally can't cut or cleanly engrave clear acrylic.

Laser Engraving & Cutting, in plain language
If you're new to lasers, the three technologies below are the starting point. Each uses a different wavelength, and wavelength decides which materials a laser can actually process.
Diode
The common desktop entry point. Blue diode lasers engrave and cut wood, leather, paper, and many coated materials. They're the most affordable enclosed option, but generally can't cut clear acrylic or mark bare metal.
CO2
A common choice for stronger cutting and a wider material range. CO2 lasers process clear and colored acrylic, wood, leather, and paper. They cost more and take more space than a diode, and don't mark bare metal.
Fiber
Primarily relevant to metal marking, engraving, and specialized metal work. A 1064nm fiber laser is the technology that bare metal actually absorbs — the work diode and CO2 lasers can't do. Fiber systems cost more and usually have a smaller work area.
For a deeper comparison, our Types of Laser Engravers: Diode vs CO2 vs Fiber guide is in progress.

Learn the laser basics
A few concepts explain most of the differences between machines. Each one matters more than a single wattage number.
- Optical power
- Measured in watts, optical power affects cutting depth and speed more than engraving detail. Higher wattage helps with thicker materials; lower wattage can be ideal for fine surface engraving.
- Work area
- The usable bed size limits how large a single piece or batch can be. Larger beds suit signs and production; smaller beds keep the footprint desktop-sized.
- Enclosure
- An enclosed machine contains smoke and stray light and simplifies safety planning. Enclosure does not remove the need for ventilation.
- Ventilation
- Cutting and engraving produce smoke and fumes. You need exhaust to the outside or a certified air filtration system sized to your machine and materials.
- Air assist
- Directed air at the cut point reduces charring, manages smoke, and lowers flare risk. Some machines include it; others need it as an add-on.
- Software
- Manufacturer apps match their hardware's features; LightBurn and LaserGRBL offer finer control. Workflow matters as much as feature count for a busy shop.
- Material compatibility
- A laser's wavelength decides what it can process. Always confirm a material is safe and appropriate before cutting or engraving it.
Find your fit
Choose by what you want to do
Match the laser to the work you actually plan to do. Linked cards lead to published guides; others are topics we're researching.
Engrave wood and craft materials
Surface engraving and light cutting on wood, leather, and coated crafts. Diode and CO2 both work; power and detail trade off.

Bare metal needs a 1064nm fiber or IR laser. This is the defining reason to choose a fiber-capable system.

Responsible laser use
A laser is a powerful tool and an ignition source. These points are general guidance, not operating instructions — always follow your machine's documentation.
Follow manufacturer instructions
Read and follow the safety and operating instructions in your machine's documentation. They reflect the specific risks of that hardware.
Ventilation matters
Even enclosed machines need proper smoke and fume management. Enclosure contains light and debris; it doesn't make exhaust optional.
Don't process unknown materials
Some plastics, coatings, and treated materials can produce hazardous fumes or damage equipment. Confirm a material is appropriate before processing it.
Never run unattended
A laser is an ignition source. Never leave a running machine unattended, keep a suitable fire extinguisher nearby, and follow fire-safe work practices.

Laser Engraving frequently asked questions
Most modern desktop machines do both. Engraving removes material from the surface; cutting passes all the way through. The same laser can often do both — what changes is power, speed, and the number of passes.
For many beginners, an enclosed diode is the easier entry point: smaller, cheaper, and simpler to ventilate. CO2 makes sense when clear acrylic or heavier cutting is central to what you make.
Yes. Diode and CO2 lasers both engrave and cut wood, with capability depending on power, material thickness, and settings. Always use air assist and follow safety guidance.
Bare metal generally needs a 1064nm fiber or IR laser. Diode and CO2 lasers can't reliably mark uncoated metal without a marking agent.
Yes. Cutting and engraving produce smoke and fumes. You need exhaust to the outside or a certified filtration system, even with an enclosed machine.
Manufacturer apps like xTool Creative Space, Falcon Design Space, and Glowforge Print are common; LightBurn and LaserGRBL are popular third-party options. Not every machine supports every package — confirm compatibility before buying.
