Powder bed fusion (PBF) is an additive manufacturing approach that is the basis for some of the most versatile 3D printing methods. In PBF, a heat source fuses a powdered material together in a layer-by-layer process. Some PBF processes sinter the material, which is when a powder coalesces into a solid without liquifying; others truly
Abstract. This study is focused on the individual effect of gas porosity size and location on fatigue strength of a laser powder bed fusion Ti6Al4V alloy. Tensile and fatigue samples were manufactured by artificially seeding gas pores either at the centre or close to surface. Seeded porosity reduced the ductility by 20% and fatigue strength by
A platform lowers the model accordingly. Powder Bed Fusion – Step by Step. A layer, typically 0.1mm thick of material is spread over the build platform. A laser fuses the first layer or first cross section of the model. A new layer of powder is spread across the previous layer using a roller. Further layers or cross sections are fused and added.
