Analysis of Resistance to Impact Loads by Charpy Type Test on Specimens Elaborated by Means of Polyjet Additive Manufacturing

Abstract

3d printing has established itself as a key element in manufacturing worldwide, finding essential applications in various industries, from aerospace to medical. The PolyJet additive manufacturing technology is a system that uses resin to build objects layer by layer, employing uv light exposure to immediately harden each layer. An inherent characteristic of objects manufactured using PolyJet is their anisotropy. The aim of this article is to analyze the impact resistance of pieces manufactured using PolyJet by utilizing the Charpy-type test according to astm d 6110. For this purpose, 12 specimens were fabricated and tested with veroclear rgd 810 resins on an objet 260 eden machine. These tests provide crucial data to evaluate how the orientation of printing affects the impact resistance of the pieces. his study contributes to ongoing research on the impact resistance of products manufactured using PolyJet, adding to the growing body of knowledge in the field of mechanical properties of these products. It is anticipated that these findings will have a significant impact on how PolyJet technology is utilized in various industrial applications
