3D print techniques in dentistry have started to become an everyday part of clinical practice. The aim of our study was 3D objectification of stereolithography system (SLA) printed models,including surface analysis. Our investigated group consisted of 50 scans of upper dental arches of medical students obtained by 3Shape TRIOS 3 ® in the form of standard template library (STL) files. SLA 3D printer-built layers of an upper dental arch model were made by using liquid polymer hardened by laser beam (blue 405 nm laser). Each 3D SLA model was scanned from 56 positions and a section to check the precision of reconstruction. The model surface was evaluated with a profilometer, scanning electron microscope, and stereomicroscope. Differences between the intraoral scanned digital STL models and 3D SLA prints were very small, namely in hundredths of mm, and in many cases, they were also significant at lower levels.
