Laser Powder Bed Fusion (LPBF) Process
The LPBF parameter space consists of laser power, scan speed, laser spot size, scanning strategy, feedstock, part geometry, and machine conditions. The selection of process parameters determines the resulting microstructure and component properties.
Various libraries of process parameters for a given machine and material have been determined through physical testing by AM suppliers or individual laboratories. An integrated computational materials engineering (ICME) approach reduces the amount of physical testing and informs design engineers about detrimental performance expected for specific process parameters.
