These initial applications either\u003c\/p\u003e\u003cp\u003eTake advantage of the relatively high surface roughness of the process\u003c\/p\u003e\u003cp\u003eAre in fatigue, corrosion, or flow environments where surface roughness-higher than that found in cast, machined, or sheet metal products-does not impose performance penalties\u003c\/p\u003e\u003cp\u003eTo move to the next levels of performance, the surfaces of components made by L-PBF and EB-PBF will need to be smoother than the current as-printed surfaces and will have to achieve this on increasingly more complex geometries. Finally, these surfaces will need to be produced without significantly increasing the cost of the final component.\u003c\/p\u003e\u003cp\u003eIn this third part of an ongoing series on AM, the challenges, technologies, and opportunities for surface finishing of L-PBF and EB-PBF metallic parts are discussed.\u003c\/p\u003e\u003cp\u003eNOTE: SAE EDGE Research Reports are intended to identify and illuminate key issues in emerging, but still unsettled, technologies of interest to the mobility industry. The goal of SAE EDGE Research Reports is to stimulate discussion and work in the hope of promoting and speeding the resolution of identified issues. These reports are not intended to resolve the challenges they identify or close any topic to further scrutiny.\u003c\/p\u003e\u003cp\u003eNotes on terminology: \u003c\/p\u003e\u003cp\u003eSurface Finishing refers to the use of in-situ processing or post-processing to smooth the surface of a part made using PBF. A primary example is sanding.\u003c\/p\u003e\u003cp\u003eSurface Improvement refers to the use of in-situ processing or post-processing to impart compressive residual stresses on the surface of a part to improve fatigue properties. A primary example is shot peening.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Kevin T.
