safeEtch
prototype
Automated support removal and finishing technology
for metal Additive Manufacturing
No more manual support removal
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.

Production capability increased in 3 simple steps
Perfect surface and sharp edges
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.

The 4 safeEtch design principles

Safety design
Internal filters connected to reaction chamber ensure that all dangerous gasseous byproducts, including NOx are neutralized. During device design, ease of use and user safety were no. 1 priorities.

Support design
All concerns regarding tradeoffs between support stiffnes and ease for removal are in the past. Process of optimum support design is automated with dedicated software.

Ultrasonic agitation
High intensity ultrasonics ensure constant flow of the etchant in internal features and enables removal of solid or gaseous byproducts. Ultrasonic cavitation prevents localized corrosion and provides high uniformity.

Etching solution
Chemicals are designed to provide fast reaction to dissolute supports within minutes and without any pitting risk. No organic solvents are used and etching solution is neutralized right after the process.
