AtomStack Kraft Lite 40W
At €2335, the Atomstack Kraft Lite 40W sits between 20W open diode lasers (€1200-1600 without an enclosure or camera) and machines like the xTool S1 40W (€2700, double the optical power but without a dedicated IR module). The combined 20W + 1.2W IR module allows for metal marking without additional heads, and the Class 1 enclosure with camera and passthrough offers a ready-to-use system for those producing customized objects in small to medium runs. Compared to a 40W open diode laser with an aftermarket upgrade, you lose cutting power but gain safety and immediate versatility; compared to an S1 40W, you save around €400 while maintaining metal marking, at the expense of a single cutting pass on wood thicker than 18mm.
