RENA Technologies offers three systems for postprocessing metal additively manufactured parts: the H3000, which accommodates parts up to 300 by 300 by 150 mm; the H6000, for parts up to 500 by 500 by 350 mm; and the H12000, which is a fully automated industrial finishing system that integrates with AM process chains.

The H12000 reportedly can postprocess up to 500 parts per hour and is capable of handling four different materials simultaneously.

Underpinning the operation of all three models is the company’s proprietary Hirtisation technology, which was developed specifically for the post-treatment of 3D-printed metal parts. The fully automated chemical/electrochemical process removes support structures, powder cake, and partially melted particles from 3D-printed metal parts; it also levels and cleans part surfaces.

Hirtisation is suitable for all common metals and printing technologies, according to the manufacturer. The treatment media are material-specific and guaranteed to treat surfaces gently.

Besides the AM sector, RENA supplies wet-chemical surface treatment equipment to the semiconductor, medtech, glass, and solar-energy industries.
