Presentation Title Investigation of the Surface Roughness of Micromilled 316L Stainless Steel Fabricated by FDM/FFF Technology

On-Site Speaker (Planned) Syed Faruqui
Abstract Scope This study explores how 3D printing parameters, specifically raster angle and layer thickness, affect the surface finish of 316L stainless steel parts after micromilling. The parts were printed using BASF Ultrafuse 316L filament on a MakerBot Method X printer, with raster angles of 0°, 30°, and 45°, and layer thicknesses of 0.1 mm and 0.2 mm. Prints were made in flat and edge orientations, then sintered in a furnace to create solid metal parts. After sintering, micromilling was performed in three directions (0°, 90°, and 180°) to investigate the surface finish of the 3D printed parts. Surface roughness was then measured to understand the impact of the different printing parameters. The results showed that layer thickness had the most noticeable effect on roughness, especially at 90°. Raster angle and build orientation also seemed to play a role, but their influence wasn’t always consistent or statistically significant across all samples.
