Title: Studying Influence of 3D Printing Parameters of PETG to Improve Hardness and Maximum Tensile Strength †
Keywords: 3D printing, mechanical properties, regression analysis

Abstract: 3D printing is increasingly used in industrial practice as an important additive technology. Both the choice of material and the printing parameters play a critical role in the mechanical and physical characteristics of parts 3D printing parameters play a major role in the strength of parts, the efficiency of the technology, and the production time. All this requires solving optimization issues using mathematical models in order to find balanced technological solutions. In this article, the main mechanical properties of PETG—hardness and maximum tensile strength, produced with different printing parameters—will be investigated. This study was conducted through a planned experiment with the aim of reducing the experimental samples without compromising the experimental results. The experimental results were statistically processed using MiniTab 13 experimental samples were tested with the following printing parameters—speed in the range of 40–120 m/min and a layer thickness between 0.1 to 0.4 mm. The aim of the article is to investigate in which discrete zone of 3D printing parameters the parts have the highest strength characteristicshardness and maximum tensile strength.
