While the Kraft 40 W is our powerhouse for deep cutting at a higher speed, it uses a blue diode laser. For high-contrast engraving on gold, silver, or bare steel, check out the AtomStack Kraft dual laser cutter & engraver with its dual 20 W diode laser and 1.2 W infrared laser for engraving.
Why customers buy it
Higher power for real cutting performance
The 40W diode output gives users stronger cutting ability than lower-power diode systems, helping reduce passes and improve throughput on thicker materials. Official listings position it for heavy wood and acrylic work compared with lighter hobby units.
Safer enclosed workflow
The enclosed Class 1 structure, lid detection, tilt detection, emergency stop, and fire-safety features make it easier to place in maker spaces, engineering labs, and supervised education environments than open-frame designs.
Camera-assisted precision and faster setup
A 16 MP camera helps with positioning and job alignment, which is especially useful for batch engraving, scrap material placement, and reducing setup errors.
Fast operation for makers and small business use
With speeds listed up to 600 mm/s, the Kraft 40W is aimed at users who need more than occasional crafting and want a machine that can handle repeatable project work more efficiently.
Flexible software compatibility
Support for AtomStack Studio, AtomStack App, LightBurn, and LaserGRBL helps users work in the software they already know instead of being locked into one ecosystem.
