In this research, an experimental analysis of the influence of layer height, build orientation and post curing on the tensile mechanical properties of SLA 3D printed material was performed. The material "Grey Resin" from the manufacturer Fromlabs was specifically analysed. When it comes to layer height, four different layer heights were analysed, with 160, 100, 50, and 25 microns. Specimens were manufactured in three different build orientations (vertical, side and flat). All specimens were tested with and without post curing (30 min, 60 °C). The results in further text showed that the layer height, build orientation as well as the post curing have an impact on the tensile mechanical properties of the SLA "Grey Resin" material. Also, in addition to the effect on mechanical properties, the paper presents how these factors affect the time of 3D printing.
