SLS/ SLM process

Single pass of a laser beam over a pre-deposited layer of steel powder particles. In this simulation DEM particles are placed on top of the solid, underneath substrate, which is modeled via the finite difference method (FDM). Particles colored red indicate that they have melted.



Side view of the same simulation. Notice how part of the underneath substrate layer is also melted (in addition to the particles). This is desirable to ensure proper bonding between layers during the SLS/ SLM process.
