The paper presents an application of the Additive Manufacturing (AM) technology using the Objet 3D Printer to develop femoral component of total knee endoprosthesis patterns for investment casting process. The goal of the paper is to outline the manufacturing technology intended for prototype production with the use of PolyJet technology and investment casting technology for use in orthopaedics and the surgery of knee arthroplasty. At present the research is focused on the preparation of STL data and verification of the production technology of prototypes made using PolyJet photopolimer materials. The wax model of knee implant obtained by Precision Casting Foundry (LPO) Ada was used as an initial model in this research and the production of knee implant prototypes was carried out in the Center for Numerical Simulation and Digital/Rapid Prototyping at the University “Eftimie Murgu” Resita, Romania.
