The Problem Statement
The Laser Powder Bed Fusion (LPBF) process used in Moog’s Additive Manufacturing Center (AMC) is complex with a multitude of variables, any one of which…if incorrect…can result in poor-quality and unusable parts. One of the primary challenges for setting up an LPBF additive manufacturing (AM) machine resides, therefore, in the proper optimization and control of the various parameters along the process chain.
Sources of Variation
The 6-Ms from the Six Sigma discipline provide a context here for what potentially would influence variation in an LPBF process and therefore require quantification and control of their associated effects.
