| Abstract Scope |
Laser Powder Bed Fusion (LPBF) process is one of the most well-known additive manufacturing methods for the production of complex and functional parts from metal powder material. Residual stresses cause a major setback in the LPBF process and restrict the serviceability of the parts, particularly in advanced technology applications.
In this study; the influence of scanning strategies, laser power, exposure time, volumetric energy density, hatch distance, point distance, layer thickness, preheating of the baseplate, and separation from the base plate were analyzed for 17-4 Precipitation Hardened (PH) stainless steel parts manufactured by LPBF additive manufacturing system in terms of residual stress accumulation on the surface and close to the very surface region by X-Ray Diffraction (XRD) method. The as built parts’ residual stresses could be reduced by up to ~67%. |
