Molecular Dynamics Simulation of Selective Laser Melting — Fabio Oelschläger¹, Azad Gorgis¹, Dominc Klein¹, Sarah Müller², and •Johannes Roth¹ — ¹FMQ, Universität Stuttgart, Germany — ²GSaME, Universität Stuttgart, Germany

Traditionally, manufacturing has been subtractive which means removing material from a workpiece. Additive manufacturing on the other hand is defined by successive addition of material and fusion with the help of heat for example. Here we report atomistic simulations of selective laser melting (SLM) used to produce additive manufactured objects. After a short introduction into the subject we present challenges to SLM. Next, modifications to basic molecular dynamics simulation are described which are required to simulate the annealing process. Although the sample sizes studied are already impressively large, scaling of system parameters are required to relate simulation and experiment. First results from the study of single and rows of spheres will be reported and further developments and improvements will be addressed.
