Surface Treatment:
The whole surface treatment is to apply the surface treatment process to all surfaces of the entire part. When we finish the process, all surfaces’ performance and appearance color on the metal part are the same. So there is no need to do a special mask and protection of the mechanical part.

Surface treatment creates an electron bombardment that breaks the surfaces chemical bonds while the ions hitting the surface are designed to alter the chemical composition of the surface. … The treatment of metal is a process in which parts or components made out of metal are treated before any actual coating takes place.

Surface treatment, or finish, is another competitive advantage of additive manufacturing. Specifically in orthopedic markets, where post-processing of traditionally manufactured components is both time-consuming and a quality concern, the additive process allows parts to be produced with any type of lattice on the surface.
