Abstract:
This paper presents the advantages and the process of making of complex functional parts using additive manufacturing technology. Design and manufacture of components were performed at the Laboratory for Technology of Plasticity and Processing Systems at the Faculty of Mechanical Engineering in Banja Luka. The parts were designed using SolidWorks and Catia software packages, then CatalystEX and Simplify3D software packages were used to process the CAD model and to prepare it for 3D printing, which included defining of the process parameters, generating layers and support. Functional parts were produced on 3D printers based on the principle of material extrusion. The results of this study show that additive manufacturing technology, specifically, technology based on material extrusion enables the production of complex functional parts very fast, with high accuracy and precision and a much lower cost and development time compared to conventional technologies.
