Title: INVESTIGATION OF THE INFLUENCE OF PARAMETERS IN 3D PRINTING OF NYLON CF15 CARBON ON LINEAR DEFORMATION DURING TENSILE CREEP
Keywords: 3D printing, mechanical properties, nylon carbon, optimisation, regression analysis, tensile creep

Abstract: In the material science creep is the tendency of solid materials to be slowly deformed at stresses beyond the yield point. The aim of this article is to investigate influence of 3 printing parameters on linear deformation during tensile creep at a constant temperature of 40°C on Nylon Carbon samples. To refine the experimental results, a planned experiment was carried out with variables – printing temperature, filament thickness and printing speed. Twenty experimental results were processed using statistical processing software in order to obtain a regression mathematical model describing relationship between 3d printing parameters and tensile creep. The tests were processed with duration of 2 h using weight of 50 kg. The equipment used for the purposes of the article was calibrated with a high accuracy. The test conditions defined in the ASTM D6992 standard in terms of atmospheric conditions and humidity were met.
