A glass tube, a water loop and an exhaust, all bought together · review
A desktop CO2 laser with a 45 W tube and a 12 × 8 inch workspace, rated to cut 0.4 inch acrylic and 0.31 inch wood, with LightBurn support.
OMTech raises the classic K40 to 45 W, and adds air assist that follows the laser power and a honeycomb bed with a detachable section for irregular objects.
LightBurn and LaserGRBL support is a real improvement over the old K40 software.
CO2 machines need cooling and an exhaust route. Read the manual for what is included. Plan the exhaust before the machine arrives.

The listing claims 0.4 in (10 mm) acrylic and 0.31 in (8 mm) wood.
A CO2 laser cuts clear acrylic and thicker wood. A diode does not cut clear acrylic.
Taken against the median of its own bench on this site — not against the whole of the maker market.

The way into CO2. The small bed is the trade-off, so make sure your work fits.
