Currently, three-dimensional (3D)-printing materials are widely used in various fields, and the challenging task is to develop optimization models that simultaneously consider tensile strength, wear resistance, print speed and material usage to find the best trade-offs for different applications. The new composite materials can significantly increase tensile strength and wear resistance of 3D-printed parts. This study aims to investigate the mechanical, tribological and morphological aspects of 3D-printed specimens under various processing settings.
The tensile and wear specimen were printed using various printing materials such as onyx, onyx with glass fiber and onyx with Kevlar. The selected infill patterns are triangular, gyroid and hexagonal. The infill densities are 30%, 40% and 60%, respectively.
The performance parameters of various 3D-printed objects are analyzed using a variety of testing methods, including tensile, wear analysis and scanning electron microscopy analysis. The designs of experiments are planned as per response surface methodology optimization technique, and optimal process parameter combination is analyzed.
This research specifically investigates the tensile strength and wear resistance of pure onyx, onyx reinforced with glass fiber and onyx reinforced with Kevlar, which have not been previously examined. These findings emphasize the importance of optimizing infill density, pattern and material type.
