Abstract

The MERCUR research project Pr-2017-0003 "Analysis of the product development process in the combination of additive and subtractive manufacturing processes for the manufacture of multi-material products" combines different manufacturing and post-treatment processes to connect the respective advantages. The additive fused deposition modeling (FDM) together with the anisotropic component properties resulting from the process are used in this investigation. The influence of chemical and mechanical post-treatment steps on these properties will be investigated.
