LitEndo - Lithography‐based Metal Manufacturing (LMM) for the production of patient-specific endoprostheses

The Austrian-German cooperation project LitEndo plans to exploit the geometric LMM potential for osseointegrative structures in patient-specific hip sockets. Compared to the industrial casting standard, this will enable the production of a new generation of hip sockets that are specifically tailored to the needs of patients and at the same time offer better osseointegration and high biocompatibility. The lithography- and sinter-based approach, including lower layer thicknesses (compared to L-/E-PBF), achieves a higher surface quality during production, which means that even threads can be printed directly and functional surfaces require less post-processing. This enables direct cost savings along the process chain and a profitable business model. Biocompatible titanium alloys and the industry standard CoCrMo are considered as materials.

The ISM sub-project is developing the heat treatment strategy for LMM-printed green parts. The focus here is on achieving standard-compliant and market-typical requirements with regard to the chemical composition of the sintered components and their mechanical properties.
