ACCURACY ANALYSIS OF ADDITIVE TECHNIQUE FOR PARTS MANUFACTURING

Abstract

The article introduces accuracy analysis results of additive technique used for manufacturing of parts depending on the used Rapid Prototyping technology. The main goal of the research was to complexly analyse dimensional and shape accuracy of parts manufactured by means of the selected 3D printers, and to compare the obtained results with the parameters given by the printer manufacturers. Devices such as Stratasys Dimension SST 768 printer using the FDM principle and Objet Connex 500 using the PolyJet Matrix were used for the verification purposes. The measurement of the selected models was performed using modern optical digitisation methods, specifically by means of 3D contact-less scanners. The subsequent data evaluation and verification of the actual part compared to the nominal CAD model was performed using GOM Inspect Professional.
