1. Initial surface finish of parts produced by powder additive manufacturing

Before introducing surface finishing techniques, it is useful to understand the origin of the surface roughness observed on parts resulting from [BM 7 900] powder bed additive manufacturing, and to quantify it for a few concrete cases. This point also aims to define the surface quality objectives for which subtractive surface finishing techniques are employed, namely surface roughness and material removal.

1.1 Origin of surface roughness

The surface finish of parts produced by additive manufacturing is influenced by six effects described in the points below:

staircase effect and layer thickness,
...
