This project aims to develop a comprehensive process route that combines additive manufacturing techniques (MEX/M and MBJ) with a subsequent press-sintering process, enabling the production of high-performance components from both hard metals and common sinter-based AM materials. Work at the ISM focuses on optimizing the green parts: by selecting suitable sintering additives and application methods, sintering activity in the surface region is increased, resulting in a dense outer layer during the subsequent press-sintering step. The green parts produced are characterized optically, microscopically, and chemically, and after sintering are analyzed for dimensional accuracy, density, microstructure, and composition. Based on these results, optimized green parts are transferred into the press-sintering route to develop a robust, industry-ready process. In addition, test geometries are manufactured and characterized to derive design guidelines for future component and series production. The ISM's work is closely linked to the development of the overall process route and to the validation of accompanying simulation methods together with the project partners, forming a key building block of the entire process chain.
