Abstract

This paper presents a comparative study on the effect of multi-machine laser powder bed fusion manufacturing on the quality of 316L stainless steel parts. Within industry, often the same additive manufacturing machines are used for research and development of components as are used for production. However, there is a challenge in terms of determining how the machine set-up and resulting part quality from one machine translates to another machine. This work determines the effect of varying machines and operators on the resultant part qualities. A build plate with specimens designed for the quantification of key material parameters was designed and manufactured on three different EOS M280 machines at different locations. This research shows the requirement to develop optimised part parameters for each AM machine and also the requirement for the standardisation of powder bed packing, which directly affect the build quality.
