Our take on the OMTech 90W CO2 Laser Engraving and Cutting Machine 20 x 28 in

The OMTech 90W is a floor-standing CO2 laser cutter and engraver with a 20 x 28 in working area and two interchangeable beds: a honeycomb table for engraving and an aluminum blade table for cutting. The 90W tube cuts up to about 10 mm in wood and acrylic and engraves at up to 600 mm/s with 0.01 mm processing accuracy. It is a 474 lb galvanized steel machine with a cover interlock and control-panel key lock, so it needs a dedicated space, exhaust, and a 220V circuit. It sits in the mid-to-upper range of hobby-to-prosumer CO2 lasers, well above 40–60W desktop units and below 130–150W production machines.

Pros
  • 90W tube cuts thicker stock than 40–60W hobby lasers
  • Large 20 x 28 in bed fits full sheets of acrylic and plywood
  • Two beds included: honeycomb for engraving, blade table for cutting
  • Cover interlock and keyed control panel add basic safety
  • Runs Ruida-style DSP control with LightBurn compatibility
  • Galvanized steel frame holds alignment better than open-frame kits
Cons
  • 474 lb and roughly 59 x 40 x 32 in: needs a permanent spot and help to move
  • Requires strong exhaust or filtration, plus air assist and usually a chiller for long runs
  • 220V power and a dedicated circuit are typically needed
  • Not a plug-and-play appliance: mirrors, lens, and bed need alignment and learning
  • Shipping is freight; crating and liftgate access take planning

What reviewers say

Owners of OMTech CO2 machines generally report solid cutting power for the money and good support for a Chinese-built laser, but expect setup work. Common complaints center on alignment out of the crate, exhaust and cooling add-ons, and freight handling.

Pros
  • Strong cutting power for the price at 90W
  • Large bed size for the class
  • Responsive support and available replacement parts
  • Sturdy steel frame that holds alignment
Cons
  • Needs mirror and lens alignment after delivery
  • Loud without a good exhaust setup
  • Cooling and air assist are extra purchases
  • Freight delivery and crating issues reported by some buyers

Questions and answers

Is 90W enough to cut 10 mm plywood?
Yes, in multiple passes at moderate speed with air assist. Clean, single-pass cuts are more realistic around 5–6 mm; dense or glue-heavy plywood may need slower speeds or two passes.
Do I need a chiller?
For anything beyond short engraving sessions, yes. A 90W tube needs active water cooling, and a CW-5000-class chiller is the usual pairing; a bucket and pump works only for brief jobs.
Does it work with LightBurn?
Yes. The DSP controller is compatible with LightBurn, and most owners run it that way rather than with the bundled software.
What power does it need?
Plan on a 220V single-phase circuit. Confirm the outlet and breaker with the seller before delivery, since 110V versions and voltage requirements vary by listing.
What comes in the box?
The machine, laser tube, water pump, air pump, exhaust fan and hose, focus tool, and basic accessories. A chiller, rotary attachment, and filtration are usually sold separately.
When is it cheapest?
OMTech discounts most around major sales events and on refurbished or open-box units. Prices also move with freight promotions, so compare the delivered total, not the list price.
