In this paper we have investigated the shrinkage and accuracy of indirect selective laser sintered aluminium. The majority of the ∼1.2‐1.4% linear shrinkage occurs during the infiltration of the skeleton structure. By optimising scale and offset parameters during selective laser sintering of the preforms, accuracy similar to that of casting processes can be achieved.
