More than 50% of the raw materials handled in industry appear in particulate form, which is why an optimal powder might be of interest for industry. However, it is obvious that optimal needs to be defined for each application in a different way. This research project is focused on the SLS-3D printing process, where repeatedly layers of particles are created and sapped by a laser to create the final product.

A Discrete Element Method is used to analyze the behavior of the particles in the layer. Moreover, the impact on the density of particles per volume depending on the friction and damping properties of the particles is examined.
