Abstract:
Sinter Based Additive Manufacturing (SBAM) processes are receiving much attention as an alternative to LPBF processes for the rapid production of metal and ceramic components with reduced cost and environmental impact. On the other hand, the sintering step is sometimes difficult to perform for green parts from SBAM process resulting in high residual porosity. This paper proposes a versatile alternative with FAST/SPS hybridisation. The FAST/SPS process is recognised as an R&D method capable of producing high performance parts from a wide range of materials. In recent years, significant progress has been made in overcoming the two main limitations of the technology: production capacity and geometric constraints. An important industrial breakthrough is presented here, with the development of a unique hybrid process that enables the consolidation of 3D SBAM parts by FAST/SPS. It allows green parts to be fully densified (porosity <1%) immediately after printing in a single step and with less than 2 hours of thermal treatment.
