Testing materials used for 3D printing

Abstract

The paper addresses issues related to 3D printing in repairing military equipment. It quoted a short story on the invention of the 3D printer and the development of printing technology. The significance of knowledge of the materials employed in 3D printing is discussed in the further part. To this end, the authors reviewed selected strength-related tests (tensile strength, in particular), to determine their application possibilities. Test samples were prepared based on a Polish standard and the material provided by two manufacturers. The tests were conducted using a Zwick Roell Z100 machine. The obtained results were presented as graphs. The paper is concluded by a short summary and an indication of further research.
