Polypropylene is a semi-crystalline polymer and thus consists of ordered and disordered domains. The arrangement and orientation of the ordered - "crystalline" - areas depend on the manufacturing process and the used process parameters. This in turn has a strong influence on the resulting material properties. Therefore, the investigation of process-related material parameters is an extremely important part in the design process of 3D-printed components. It has been shown that a variation in the printing temperature or speed significantly changes the resulting crystal structures and thus the mechanical and thermal properties of the material.

Polypropylene is one of the most common polymers. It can be used both in infrastructure as well as for special applications using 3D-printing.

The article will be published in Volume 35 of "Additive Manufacturing" in October 2020.
