ICTM Aachen – International Center for Turbomachinery ManufacturingReduction of Cracks in LPBF Components by Means of Modulated Laser Radiation
Is it possible to avoid cracks in L-PBF components by using modulated laser radiation?
Challenge and Motivation
- High performance superalloys tend to crack during processing by means of LPBF.
- In particular, components made of superalloys benefit from the geometric freedom of LPBF.
Objective
- Avoid cracks during processing of a superalloy using LPBF and modulated laser radiation.
- Demonstrate the feasibility for a selected complex application-relevant component.
