The process has been specifically developed for the post-treatment of 3D printed metal parts. The method is suitable for all common metals and alloys and all types of printing technology used in additive manufacturing (LBM, EBM, ...).
Hirtisation® is based on a combination of electrochemical pulse methods, hydrodynamic flow and particle assisted chemical removal and surface treatment. The treatment media used in this multi-step process are material-specific and guarantee a gentle surface treatment. There are no mechanical processing steps involved.
Over several process steps adhering powder cake and support structures are removed. Partially sintered metal particles and burrs typical for surfaces of as-printed parts are reproducibly removed and the surface roughness is significantly reduced. Hirtisation® does not only affect the outer surface of the component but also reaches deeply into cavities and geometric undercuts.
Thus, the process offers the unique possibility to use all the freedoms of metallic 3D printing and acts as an enabler for the whole metal 3D printing industry.
