Simulation for Selective Laser Sintering of ceramics
Additive manufacturing is a fast growing field: it started with processing of plastic materials in the 80s and it was extended to metals in the late 90s. Ceramics is the next challenge for engineers and researchers and this is the reason why a joint project between ETH Zürich, EMPA and PSI started
The project will start with a comparative analysis of different techniques for simulation of melt-ing/sintering of ceramic powder bed. The next step consists of developing a simulation for better understanding the physical phenomena involved in SLS. Experiments of laser absorption of the powder bed will be conducted for evaluating the input parameters, as well as melting experiments will be conducted for validation of the results. The main challenges consist in identifying what are the important physical phenomena that must be included in the simulation and how to implement these phenomena in the simulation.
