Accuracy analysis of the CAD models reproduction for polymers parts, produced using additive manufacturing at manufacturing process based on Industry 4.0 convention

摘要

This paper presents the methodology and quality assessment results for machine parts produced directly from CAD 3D numerical model. The parts were produced using representative additive manufacturing technologies based on polymers and UV light-cured resins processing and their properties were analyzed. The whole process was conducted according to Industry 4.0 convention. The assessment of the reproduction accuracy of CAD 3D models covered the quality of external surfaces, volume of manufactured parts as well as dimension accuracy.
