FIDENTIS Redefines Dentures Through Multi-Material 3D Printing

FIDENTIS is a startup aimed at changing dental manufacturing methods, incubated by the Fraunhofer IGCV Institute, which is one of the globally recognized leaders in metal multi-material additive manufacturing research.FIDENTIS Redefines Dentures Through Multi-Material 3D PrintingFIDENTIS focuses on multi-material 3D printing solutions for denture design, combining laser powder bed fusion with robotic systems.FIDENTIS Redefines Dentures Through Multi-Material 3D PrintingThe company’s multi-material solution is based on the laser powder bed fusion (L-PBF) process, which can combine two or more alloys into a single component. With precise control from robotic arms, additional powder is deposited in the bed layer, perfectly synchronized with the manufacturing process. The company has also customized laser and scanning path parameters to ensure optimal fusion between materials, resulting in fully dense parts with high dimensional fidelity. The solution integrates a digital production chain for automatic post-processing of functional surfaces.FIDENTIS Redefines Dentures Through Multi-Material 3D Printing

Compared to single-material 3D printing, the complexity of multi-material additive manufacturing is at least three times higher. It is no longer just about mastering one material, but about mastering two (or more) materials and their interactions at the interfaces. This complexity is reflected in every stage of the process: from data preparation to monitoring during the printing process (scanning, powder deposition, etc.), all the way to post-processing (heat treatment, machining, powder recovery, etc.). FIDENTIS® has been engaged in multi-material additive manufacturing for over 7 years, developing solutions that can build and stabilize the entire process, ensuring reliable and repeatable production. Nevertheless, even a single-layer scanning path can appear very complex at first glance.
