Dimension accuracy of metal components built by selective laser melting using EOS M280 (2/2)
As with any craft, it is important to understand the advantages and limitations of tools. In the case of the EOS M280, which offers one of the most powerful and flexible control software among SLM machines, it is vital to pick out the most suitable parameters amongt the 84 parameters available (and combinations!) for dimension accuracy.
Assuming a reasonably good as-built surface roughness (Ra<10um) and minimal distortion due to internal stresses, let’s identify the parameters and settings responsible for
1. in-plane accuracy (= in-layer = x/y plane parallel to building substrate),
2. accuracy in the z/building direction.
Small features (thin walls, holes, sharp angles/corners, …) accuracy or volume/dimensions variations after heat treatment will be discussed separately.
