Selective laser melting (SLM) is a very advanced and promising additive manufacturing process which is beginning to take root in the US manufacturing scene. Unfortunately, it is not fully developed as of yet and still suffers from problems; the most serious of these is the tendency of the process to trap residual stresses within the parts during the process. Overhanging and delicate features suffer particularly from this. A full-factorial experiment was designed and performed as a tool to explore this problem and provide insight into ways to deal with this problem in engineering design. The experiment utilized a simple simulation of the SLM process created by the author of an overhanging part feature in SLM to collect data. When the data and conclusions were compared to experimental data from literature, it was found to match well, indicating the experiment and simulation are useful tools for studying overhanging features in SLM.
