SLM of Polymers
To study the selective laser melting of polymers, the current numerical model for metals is transferred for viscoelastic materials. Therefore, the energy coupling of the laser source is modified regarding the different absorption and reflexion behavior of photons on polymers, e.g., the material is semi-transparent in its liquid state. Additionally, the rheological model for highly viscous and viscoelastic materials from the foam formation is reused.
