What is it about?
Applying ASTM standards for stainless steel corrosion to 316 stainless steel specimens made by the direct metal laser sintering (DMLS) process (essentially, "3D-printing" of alloy parts). Compare with corrosion of equivalent, conventionally manufactured specimens.

Why is it important?
Parts made by 3D-printing have the potential to degrade differently from conventionally manufactured parts. Consequently, its important to understand the degree to which this is the case so: (a) safety is ensured; (b) appropriate mitigation steps are taken; (c) sound decisions in terms of material/part selections can be made.
Perspectives
Given DMLS is an emerging technology, it is important to understand whether, or not, metal parts made via this route can be treated the same as "conventionally" manufactured parts.
