Abstract:
Additive manufacturing (AM) of metal components offers enormous potential for patient-specific medical applications. Endoprostheses such as artificial hip joints are already being successfully manufactured using the laser or electron powder bed fusion (L-|E-PBF) process. Recently, however, new sinter-based AM processes have increasingly come into focus. Metal binder jetting promises lower manufacturing costs with the same or higher geometrical freedom and accuracy as L- or E-PBF. Nevertheless, concrete industrial application examples are still pending. In this paper, a possible process chain and its influences for the MBJ production of Ti-6Al-4V parts is therefore presented and investigated. For this purpose, requirements for the mechanical and chemical properties are compiled, costs and cost structure as well as data preparation are investigated and compared to L-PBF.
