Many different processes are established in Additive Manufacturing (AM). The processes differ from each other in a number of points, partially significantly, such as the required support, build-up rates, resolution, material variety, anisotropy, repeatability, surface roughness, investment costs and much more. These many differences make it difficult to compare the processes and to select a suitable process for a component. In this project, the polymer-based AM will be compared comprehensively and the advantages and disadvantages will be worked out. Based on this, a tool will be developed to support the process selection. This is intended to support persons with no experience in AM as well as those with a great know-how.
