AtomStack - Kraft Dual-laser Engraver 20W Diode + 1.2W IR

Overview

The Atomstack KRAFT redefines versatility in desktop laser technology. Equipped with dual-laser integration — a 20W blue diode laser and a 1.2W infrared (IR) laser — it combines cutting depth with fine engraving precision. Switch seamlessly between blue, IR, or combined laser modes to engrave or cut virtually any material without changing optics or modules.

With a fully enclosed Class 1 design, built-in 16MP HD camera, and one-touch autofocus, the KRAFT delivers professional-level performance with uncompromising safety and ease of use. Perfect for creators, makers, and small workshops seeking industrial-quality results in a desktop-sized system.
