Additive Layer Manufacturing (ALM) is a continuously evolving method of manufacturing with new processes and workflows being suggested. Understanding of the fundamental science behind the process allows suggested new process to be based on more than just experience.
The bonding process which occurs in powder based additive manufacturing is not always well understood. The nature of ALM means that the process of bonding is occurring in 3-dimensions, to understand this requires analysis in 3D. The ability to understand the process.
