Metal-AM postprocessing is difficult and could account for over 50% of the final price. Manual labor needed for support removal is very often the most expensive part of 3D printing process.

The safeEtch allows user to automatically remove supports without mechanical treatment and polishes surface even in places inaccessible with classical tools. Technology is based on chemical reaction accelerated with high-intensity ultrasonics.

SafeEtch is protected by a patent and 2 patent applications.

With assistance of ultrasonics, etchant will infiltrate each part of printed structure also internal supports in flexible joints and complex structures.
safeEtch reduces surface roughness, including internal channels and scaffold structures. Unlike electrochemical processes, ultrasonically assisted etching removes an uniform layer of material. Not only it smoothens the surface, but also keeps sharp edges.
