Abstract: In this paper, the dimensional variation of the microstructures throughout all the steps of the Micro Metal Injection Moulding (µMIM) process, that is, injection moulding, debinding and sintering, was investigated. The dimensions of the microstructures were measured using a Veeco interferometer. Based on the measured data, global warpage, surface roughness and dimensional shrinkage of the microstructures in different processing steps were compared. Further, a preliminary study on the effect of packing pressure on the three parameters (global warpage, surface roughness and dimensional shrinkage) throughout all the steps of the µMIM process was conducted.
