Geometry- and application-adapted LPBF process control

• The process control of Laser Powder Bed Fusion (LPBF) is currently done without consideration of the part geometry and the application requirements by using constant process parameters for the entire part.
• By adapting the LPBF process control to the part geometry, there is a great potential to increase process speed, robustness and part quality.
• In addition, tailored component requirements can achieved by using different process parameters in different areas of the component depending on the desired function.
• The Fraunhofer ILT is developing this customized process control to increase the efficiency of LPBF manufacturing.
