Extrude Hone introduces Coolpulse technology, a solution for 3D printing component finishing. Intended for metal 3D-printed parts, the strategy is said to be well-suited to use in the aerospace and medical markets.

Coolpulse is an anodic metal dissolution technology similar to electro chemical machining (ECM) or electro polishing. The printed part is connected to a positive electric pole (or anode), while a printed tool that mimics its surface geometry is connected to a negative electric pole (or cathode). The surface of the printed part is machined by running an electrolytic solution between the parts while driving a controlled DC current between them. 

According to Extrude Hone, this technology offers flexibility and short reaction times to support applications such as rapid prototyping. It is said to be easy to adapt and implement, and provide reasonable material removal with acceptable edge-rounding tendancies.
