Original Kurzfassung:
Additive manufacturing (AM) has become more and more important over the
last years. As more applications for AM are found, there is a rising need for measured
material properties to advance product development and engineering. Especially impact
properties are seldom to be found. For this work, four commercially available filaments of
Polylactic acid (PLA), Polycarbonate (PC), Polypropylene (PP) and Polyamide 12 (PA12)
have been selected and test specimens have been 3D-printed using an extrusion based 3Dprinter
with three different infill orientations (0°, 45° and z). Based on instrumented charpy
tests, the force-displacement curves and the impact strength of the materials have been
analyzed regarding their infill orientation. Additionally the influence of notches has been
analyzed for PLA.
