In Laser Beam Powder Bed Fusion (PBF-LB), powder is applied to the build platform by a recoater unit performing a horizontal movement. Though not often the focus of research, the quality of powder layers has a significant influence on the quality of the final part, making the powder application process highly relevant to PBF-LB’s productivity and reliability.
A collaborative project between the Chair of Hybrid Additive Manufacturing (HAM) at the Ruhr University Bochum and the consulting firm MTS Consulting Partner has shown how the Six Sigma method can be used to improve the process of metal powder application in the PBF-LB process.
