The aim of the research presented in this paper is to examine the accuracy (to what extent the 3D print fits to the 3D model) and the precision (which establishes the consistency of the measurements) for small-sized plastic parts printed on Zortrax M200 3D printer. One of the goals of the research is to find out how much the thickness of a wall (or of a bolt) can be reduced as it still to keep its stiffness and dimensional precision. A proper method for designing part couples was targeted. In order for a part to be correctly assembled with its pair, the deviation of the physical dimensions was taken into account. Also, the results of the experimental work on the capabilities and limitations of printing technology using this printer are presented in this paper. Several parameters such as surface quality and strength, layer shifting or misalignment are closely studied.
