N2 - Components manufactured using additive technologies are produced with a rough surface and a significant amount of support material still attached. The support structures can often be easily removed with simple tooling methods, but it can be difficult to get a smooth, uniform surface finish – particularly on internal surfaces.Surface roughness is not consistent across an additively manufactured part. The orientation of a surface relative to the build plate affects its roughness; also, internal surfaces can have a harsher surface than external surfaces. A major problem is that internal surfaces are often harder to reach; making it difficult to alter their surface properties. Across the industry there is no consensus on the method of finishing which yields the best result; often, companies will use multiple steps in their finishing method.Through experimentation, it is possible to find an optimal orientation to build parts from; some build orientations improve certain features of a design. By optimising the orientation, it is possible to save time on the finishing process and achieve a better overall product. Research into mass finishing has offered a simpler way to finish parts which works on all surfaces but does not necessarily improve the consistency across the part.
