For use as a final product, it is important that the parts have good mechanical properties, high dimensional accuracy and smooth surfaces. The knowledge of the mechanical properties is very important for the design engineer when it comes to the component design. End-use products out of the FDM process have to resist applied forces. In this paper, investigations were conducted with the polymer Polyamide 12 (FDM Nylon 12) from Stratasys Inc. This polymer can be processed with three different tip sizes resulting in different layer thicknesses from 178 µm to 330 µm. Thus, the mechanical properties were determined for these layer thicknesses and for different orientations on the build platform. In addition to the mechanical properties the thermal properties (e.g. with a DSC analysis) are also investigated.}}, author = {{Knoop, F. and Schöppner, Volker}}, booktitle = {{26th Annual International Solid Freeform Fabrication Symposium}}, pages = {{935--948}}, title = {{{Mechanical and Thermal Properties of FDM Parts manufactured with Polyamide 12}}}, doi = {{http://utw10945.utweb.utexas.edu/sites/default/files/2015/2015-77-Knoop.pdf}}, volume = {{26}}, year = {{2015}}, } @inproceedings{27331, author = {{Schöppner, Volker and Fecke, N. and Herken, T.}}, booktitle = {{30th International Conference of the Polymer Processing Society (PPS)}}, location = {{Cleveland (USA)}}, title = {{{Analysis of the Material Degradation of PET on a Co-Rotating Twin-Screw Extruder for Varying Vacuum Pressures}}}, year = {{2014}}, } @inproceedings{27332, author = {{Schöppner, Volker and Littek, S.}}, booktitle = {{PolyMerTec 2014}}, location = {{Merseburg (Deutschland)}}, title = {{{Berechnung des Materialabbaus von Thermoplasten während des Plastifiziervorgangs}}}, year = {{2014}}, } @inproceedings{27334, author = {{Schöppner, Volker and Reinders, F.}}, booktitle = {{Biobased materials 2014 - 10th Congress for Biobased Materials}}, location = {{Fellbach (Deutschland)}}, title = {{{Development of Wood-Plastic Composites Based on Wood Particles and Dried Blood}}}, year = {{2014}}, } @inproceedings{27337, author = {{Schöppner, Volker and Herken, T. and Reinders, F. and Westhues, K.}}, booktitle = {{Erfolgreich Compoundieren mit Pulvern und Stäuben}}, isbn = {{978-3-18-234335-6}}, location = {{Düsseldorf (Deutschland)}}, title = {{{Simulation des Compoundiervorgangs im Doppelschneckenextruder, Modellierung - Simulation - Auslegung}}}, year = {{2014}}, } @inproceedings{27338, author = {{Schöppner, Volker and Fecke, N. and Herken, T.}}, booktitle = {{72nd Annual Technical Conference of the Society of Plastics Engineers (ANTEC)}}, location = {{Las Vegas (USA)}}, title = {{{Experimental Analysis of the Material Degradation of PET on a Co-Rotating Twin-Screw Extruder}}}, year = {{2014}}, } @misc{27341, author = {{Schöppner, Volker and Brockhaus, S. and Klie, B. and Giese, U.}}, booktitle = {{KGK Kautschuk Gummi Kunststoffe}}, issn = {{0948-3276}}, number = {{11-12}}, title = {{{Grundlegende Studie und alternative Methode zur Bewertung des Wandgleiteffekts bei hochviskosen Kautschukmischungen}}}, volume = {{67}}, year = {{2014}}, }
