11:15 Development of a Tool for Detection, Understanding and Elimination of Component-Defect-Sources in Additive Extrusion Processes for Polymers
Friedrich Bähr, GSaME, University of Stuttgart, PhD research student, Stuttgart, Deutschland
Additive Manufacturing (AM) has been discussed for years as break-through technology, bringing profound changes for series production. However, currently, AM is primarily used for prototyping. I.e. in the automotive industry, large amounts of parts with ever increasing product variety are used - improvements in flexible and high-quality manufacturing processes involve great opportunities. In this paper, a tool for detecting, understanding and eliminating sources for component defects in additive extrusion processes is presented. Research has been done at the level of part, slice and bead. To understand the process chain thoroughly, influences on mechanical properties, geometric and dimensional tolerancing and surface quality for parts built from ABS is examined. Elimination measures for sources of defects are pointed out accordingly.

Friedrich Baehr is PhD student, working on a research project at Fraunhofer Institute for Manufacturing and Engineering IPA in cooperation with Graduate School of advanced Manufacturing Engineering (GSaME), University of Stuttgart, supervised by Prof. E. Westkämper. He gained a Bachelor's degree in Industrial Engineering from University of Applied Sciences Jena in 2010 and a Master's degree in technical, innovative Entrepreneurship from University of Barcelona in 2012. Besides several short-term jobs for the automotive industry, Friedrich worked half a year for the car supplier EDAG in Detroit, MI, USA and did his Bachelor thesis project with Daimler in Mannheim, Germany. Since late 2013, he analyses extrusion based additive manufacturing processes using thermoplastic materials.
