Overview
OMTech built this desktop laser to engrave and cut wood, acrylic, leather and glass in a compact cabinet. Built-in air assist clears smoke from the cut, and door and water protection, an emergency stop and an exhaust fan handle safety.
OMTech gives hobbyists and small shops real cutting power in a desktop footprint with popular software support. The small bed limits project size, and venting smoke outdoors is still your job.
Who it's for
Signs, ornaments, custom gifts and small batch orders suit this desktop laser. Shops cutting large panels should look at a bigger bed machine.
Pros and cons
- Cuts thick acrylic and wood
- Fast engraving speed
- Built in air assist
- Safety interlocks and e-stop
- Small work area
- Heavy for a desktop unit
- Water cooling needs care
Performance notes
Air assist blows debris out of the kerf, which reduces charring and protects the lens. Cut depth depends on power, speed and passes, and thicker stock needs slower settings.
