•Optical measurement of geometric slope deviations of specimens made by 3D printing.•Determination of optimal 3D printing parameters based on optical measurements.•Determination of suitable method of slope’s measuring in additive technology.•Determination of effects of deformation using optical measurement.•Finding out the best geometric deviations of the slope. The paper aims to research optical measurements of geometric slope deviations and their differences on two types of experimental specimens. The two types of specimens have plane segments inclined in the angular range of 0°- 45° and 0°- 90°, graded after 10° and 15°. Specimens were produced as six different combinations of printing parameters of a Renishaw AM500E 3D printer. At the same time, the 3D models of specimens obtained by scanning serve as a standard for inspection. A coordinate measuring machine Wenzel LH 65 with a Shapetracer 2 optical head and an Atos Gom MV 300 scanner were used for evaluation. Based on the research, best 3D printing parameters were decided, position in the printing space of the printer and the effects of deformation triggered by supports at different inclinations of the plane segments. The analysis of experiments supplied the best geometric deviations of the slope for specimens.
