Abstract Scope |
Additive manufacturing has been used extensively for the last decade in making different parts of different complexities. One of the additive manufacturing methods discussed in this work is Free Form Fabrication/ Fused Deposition Modeling (FFF/FDM). FDM is used to fabricated stainless steel using BASF Ultrafuse 316L Metal 3D Printing Filament which is made of 80% 316L stainless steel particles in polymer base. In this work, we study the impact of the part geometry on the shrinkage percentage and density of 3D printed parts. Four basic geometries are printed: cylinders, rectangular blocks, spheres, and cones. These geometries have the same volume with the same height in the printing direction for the cylinders, rectangular blocks, and the cones. The size of the parts before and after sintering are compared with the CAD model of those parts and the density of those parts are also compared before and after sintering. |
