Diode vs CO2 laser for a home engraving side business (2026)
The job: Engrave personalised gifts (wood, leather, slate, coated tumblers, acrylic) from home and sell them at markets or online.
Short answer: a diode laser ($500-1,600) handles most gift engraving on wood, leather and slate, and can cut thin wood and dark or opaque acrylic. Get a CO2 laser ($2,500+) only if you need clear acrylic, fast cutting of thicker sheet, or glass engraving.
Why clear acrylic matters: diode lasers emit blue light at about 450-455 nm, which clear acrylic lets straight through, so it won't cut. CO2 lasers emit 10.6 µm infrared, which acrylic absorbs, and they leave a flame-polished edge. (VIP Plastics, Boss Laser FAQ.)
Budget for safety first: lasers make smoke and fumes. Vent them outdoors, typically a sealed 4-inch duct with a 150-200 CFM inline fan, or use a filtered extractor. Wear goggles rated for your laser's wavelength. Never laser PVC or vinyl: it releases chlorine-containing gas that harms you and corrodes the machine.

How we chose
- Can it do the materials your products need (especially clear acrylic)?
- Enclosed (Class 1) vs open frame: what extra safety gear you must add
- Work area vs your typical item size
- Price as listed by the maker on the check date
The picks
Creality Falcon2 22W
Plenty of power for engraving and cutting thin wood, with integrated air assist, and it works with LightBurn and LaserGRBL. The low price leaves money for the enclosure and ventilation an open-frame laser needs.
- Lowest price for a 22 W diode from a major brand
- Large 400×415 mm work area
- Air assist built in
- Open frame: you must add an enclosure or shroud, extraction and wavelength-rated goggles
- Can't cut clear acrylic (diode wavelength)
- Slower than CO2 for cutting
Skip it if: You share the room with kids or pets and can't add an enclosure, or you need clear acrylic.

xTool S1 20W (enclosed diode)
A fully enclosed Class 1 diode machine. xTool lists cutting up to 10 mm wood and 8 mm dark acrylic in the 20 W version. The enclosure contains the beam, and you still vent the fumes.
- Class 1 enclosure, so no exposed beam in normal use
- 498×330 mm work area
- 40 W version available for thicker cuts (UK price £1,599)
- About 3× the price of an open-frame diode
- Still can't cut clear acrylic
- 20 W variants were out of stock on xTool's page when we checked
Skip it if: You'll set up in a garage with good ventilation and are happy to build an enclosure.

Glowforge Aura (6W diode)
An enclosed 6 W diode from a brand known for beginner-friendly software. At 6 W it's slower and cuts thinner material than the 20 W machines, so it suits light engraving more than production cutting.
- Enclosed design
- Beginner-focused brand
- Much less power than the 20-22 W diodes here
- Costs more than the Falcon2 for less power
Skip it if: You need to cut more than thin material regularly.

OMTech 60W CO2, 16×24 in
The cheapest route we found to CO2 capability (clear acrylic, faster cutting) with a 16×24-inch bed. It's a big machine, so check the space, power and cooling requirements on the listing before ordering.
- CO2: cuts and engraves clear acrylic, glass engraving
- Large 16×24 in bed for the price
- Far more expensive than a diode, and needs dedicated space
- Check cooling and setup requirements on the listing; CO2 machines need more setup than diodes
Skip it if: Most of your products are wood and leather. A diode will do.

xTool P2S 55W CO2 (desktop)
A desktop CO2 that xTool rates for 18 mm basswood and 20 mm acrylic in one pass, all acrylic colours, and glass engraving.
- All acrylic colours, including clear
- Enclosed desktop design
- 600×305 mm work area
- Highest price here, which takes many sales to pay back
- Cutting figures are xTool's own
Skip it if: You haven't yet proven people will buy your acrylic products.

What it really costs per item
Machine price matters less per item than you'd think once you make a few thousand pieces. Your time and the blank matter more. Here's the same engraved coaster on two machines.

Safety setup to budget for
- Ventilation: vent outdoors through a short, sealed 4-inch duct with a 150-200 CFM inline fan, plus a way for fresh air to come in. If you can't vent outdoors, a filtered extractor (pre-filter, HEPA, activated carbon) is the fallback, but it's less reliable for heavy cutting (Maker Atlas, StyleCNC).
- Eye protection: goggles certified for your laser's wavelength (about 450-455 nm for most diodes), with adequate OD. Don't rely on generic tinted glasses.
- Fire: never leave a laser running unattended, and keep an extinguisher nearby.
- Banned materials: PVC/vinyl (chlorine gas). Check any unknown plastic before lasering it.

FAQ
Can a diode laser engrave stainless steel tumblers?
Usually only coated or painted tumblers, by removing the coating. Marking bare metal well generally needs a fibre or infrared laser. Check your machine's material list.
Do I need LightBurn?
Not always. Many machines include free software, but LightBurn is popular for diode lasers. Check whether your machine supports it before paying for a licence.
