This article focuses on parameters that influence production of parts by different 3D-printing technologies (FDM, Polyjet Matrix, SLA and SLS). This article acquaints its readers with data and results of research dealing with influence of production process parameter settings on the magnitude of internal material tension of the printed part, or its influence on dimension and shape precision of products manufactured by these technologies. The samples may change their properties by change in time so we are inspecting all the printed samples and analyse the dimensional and shape accuracy of each sample in three time frames (0 days, 14 days and 84 days). The produced samples were measured and their shape precision was analysed by Optical 3D contactless scanners and therefore perform shape and dimension precisions of the produced prototypes in a complex and objective manner and the effect of "aging" was researched using GOM inspect professional.
