Influence of post processing techniques on surface texture of selective laser melting parts

الملخص EN

In this work, the effects of different post processing techniques on surface texture improvement of additive manufactured parts made by Selective Laser Melting powder bed.

In this investigation Renishaw’s SLM 125 was employed to produce 3D parts by using stainless steel 316L, at Manufacturing Technology Centre (MTC) Coventry (UK).

SLM is techniques capable to produce fully dense functional 3D models direct from CAD data, similar with those made with traditional methods.

On the other, hand the major drawback is that the parts have granular poor surface finish, which ranges from 10 to 45 µm due to machine adjustment parameters.

The aim of this work is to compare surface finish improvement of SLM parts several post processing methods have been applied using Stainless Steel 316L.

All techniques showed good improvement of surface finish with some drawback on surface texture as showed in followed results.
