Preliminary Design and Analysis of Tensile Test Samples Developed by Additive Manufacturing

Additive Manufacturing (AM) is starting to replace conventional manufacturing processes where complex parts with small lead-time and lot sizes are needed. As conventional test methods are not suitable for AM parts, new standard specimens and test procedures have to be defined. This work undertakes some efforts to progress the design of specimens for mechanical tests. A methodology for tensile tests of AM specimens made from one layer is proposed and verified on an example. It identifies challenges during the design and manufacturing of Fused Layer Modeling single layer specimens.
