The interaction between powder particles during laser irradiation is one of the major factors affecting the build part in the selective laser sintering process. Due to asymmetric heating, defects such as internal voids, disjoint particles and asymmetrical shrinkages are formed within the part. This paper utilizes molecular dynamics simulation to reveal the effects of asymmetric heating on the build part.
