Experimental determination of mechanical properties of cylindrical samples made by additive technology

Abstract

This paper presents experimental results in determining the mechanical properties of cylindrical samples made by additive technology. In the past, additive technologies were used only for prototypes. Today, they are actively involved in the production, especially in the case of small series or parts with special geometric and mechanical requirements—the tested samples were cylindrical and printed on a printer German Rep Rap X400 (It is important to note that, during the test, the samples were not treated with acetone). The German Rep Rap X400 is an Industrial Quality 3D Printer with high precision, speed and printing volume. The test was performed in the control of displacement at a speed of 1 [mm/min], while the layer's height was 0.2 [mm]. The substrate temperature was 100oC, while the nozzle temperature was 245oC. The results presented in this paper can be used and are repeatable in practice and in further research.
