The Influence of Printing Orientation on Tensile Strength in SLS 3D Printed Specimens

This study delves into the mechanical characteristics of specimens manufactured through Selective Laser Sintering (SLS) technology, focusing on the tensile strength properties of PA12 materials. The tensile specimens were produced on Fuse 1 machine (Formlabs, Somerville, MA, USA) following the ISO 527 standard. Notably, the research encompasses six distinct specimen batches, each comprising five specimens, varying in printing orientation, half of them are Horizontal and the other half is Vertical. And that each H or V has 3× build orientations. This multifaceted approach offers a comprehensive understanding of how printing orientation impacts the tensile strength of PA12 specimens, thus contributing valuable insights to the field of additive manufacturing and material science.
