The industrial and fully automated chemical-electrochemical Hirtisation® process is capable of removing support structures, powder cake and partially melted particles from 3D-printed metal parts and provides a levelling and cleaning of the surface.

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, ...). 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.
World´s first industrial and fully automated autonomous Post-processing of 3D printed metal parts Hirtisation® uses a combination of electrochemical pulse methods, hydrodynamic flow and particle assisted chemical removal with no mechanical processing steps involved. Reaching deeply into cavities and geometric undercuts, up to 100 parts can simultaneously be finished in the H6000. Powder cake and support structures are removed even at inner surfaces were no mechanical treatment can be applied. Thus Hirtisation® acts as enabler for numerous part geometries.  In parallel the surface roughness will be reduced while the edge sharpness is retained.

The full capability of the Hirtisation® process is included in our H-Series fully automated finishing modules:

The H-Series can provide the key factors for the post processing part of the process chain. The unique scalability of Hirtisation® enables a reproducible, high quality finishing at any scale. With the H-Series finishing module there is no need for any error-prone manual post-treatment steps. The finishing of many parts within two runs simultaneously in the larger H-Series modules will reduce the costs for post processing significantly.
This fully automated solution integrates seamlessly into the process chain of additive manufacturing. The post processing via the finishing modules will have no influence on the material properties of the 3D-printed parts. The composition remains unaltered; the mechanical properties stay the same.

Hirtisation® is the perfect surface treatment for subsequent finishing processes as protective coatings and functional layers.


  • H3000
    H300 - fully automated finishing module...

  • The H3000 is your entry to the fully automated post-processing world of Hirtisation®. Therefore, it is specifically designed for quick and agile businesses such as on-de­mand print-shops. It offers optimal support for small-scale production of different parts and any R&D activity providing a part window of 300x300x150mm. One H3000 can handle the part feed of up to 3 AM-printers. Thanks to its modular design, the H3000 can be adjusted to various applications and provides a powerful and flexible tool for post-processing 3D-printed metal parts.
  • H6000
    Fully automated industrial finishing module...

  • Take the next step in Hirtisation® with the H6000. The big sister of the H3000 offers a larger part window of 500x500x350mm and enables a fully automated finishing of 3D-printed metal parts at industrial scale. The H6000 can handle up to two materials at a time and the part feed of up to 3-5 AM-printers. Inner buffering of production batches allow a 24h continuous production. Die H6000 was designed to fulfill the strictest environmental regulations.
