Influence of Powder Properties on Processability and Part Properties in SLM

© Fraunhofer ILT

What are key powder properties influencing part quality in SLM?


Challenge and Motivation

  • Typical nickel-based superalloy powders for SLM are produced by gas atomization and have a chemical composition close to the one used in casting or forging
  • Although powder quality is a key aspect to achieve a high part quality, the key powder properties are still not clear and not standardized


  • Acquisition and analysis of different powders for SLM
  • Manufacturing and analysis of samples
  • Adaptation of  developed procedure for identification of key powder properties for the SLM process
