Abstract

Accuracy and repeatability are among the key parameters in assessing the quality of additive manufacturing (AM) outputs, as they determine the usability of parts in technical and industrial practice. This study compares a standardized artifact defined by ISO/ASTM 52902 with a newly designed custom artifact, with measurements performed using a coordinate measuring machine (CMM) and 3D scanning. The dimensional deviations obtained for individual axes were statistically evaluated to determine whether the differences between artifacts and measurement methods were statistically significant. Additional analysis based on deviation mapping against the CAD model provided a more detailed view of process behavior for both simple and complex geometries. The results confirmed that the designed artifact can be considered a viable alternative to standardized solutions and offers advantages in practical applications, particularly in the context of quality control and optimization of measurement procedures.
