Dental models are used as working models for planning and making dental crowns and bridges. Conventional
methods are based on taking impressions of patient's upper and lower dental arches and require a labourintensive
manual process to create dental models. Manufacturing dental models digitally from 3D scans and
subsequent 3D printing simplifies the workflow, speeds the process and lowers the costs. Except significantly
reduced manufacturing time compared to conventional methods, increase in dimensional accuracy is also
noticeable. Any deviation from real dimensions, especially of the remaining dental tissues, results in non-fitting
of crowns and bridges, or failure in insertion. Nowadays, Stereolithography (SLA) 3D printing technology is
commercially available and represents an alternative technology for dental model manufacturing in terms of
production cost and speed.
Most SLA printers have small platform surface, and if there is a demand to print many models at once there i...s
a request for printing them on a steeper angle. That requires more layers of print, which may influence the
dimensional accuracy of a model. The objective of this paper was to assess the influence of selected
orientations of dental models during printing, i.e. number of layers necessary to print a part. Dimensional
accuracy was compared of dental models with 0 deg., 45 deg., and 90 deg. printing angle, according to the
platform. Printed dental models, of different printing orientations, were scanned using Geomagic Capture®
industrial-grade 3D scanner and attained models compared to .stl files, on the basis of which the printing was
performed.
