Collaborative R&D Project 2017

What is the best way to manufacture e.g. thin walled blades with internal cooling features?

Challenge and Motivation

• Manufacturing of prototypes (non-AM-design e.g. for casting) or parts (AM-design) by SLM
• Reduced shape and dimensional accuracy of critical features (e.g. hot gas path) due to local distortion
• Blocked cooling system or increased surface roughness due to supports and their removal
