Abstract

Stereolithography (SLA) printing technology is considered one of the most popular applications of 3D printing technology. Therefore, it becomes necessary to give attention to the mechanical properties of the materials printed by this technology because it directly affects the quality of the product. This article aims to provide essential parameters for improving the mechanical properties of materials through such factors as printing orientation, post-print curing time, adding nano-sized particles into the material printing. The two options that the article analyzes are printing orientation and photopolymerization technology. The analysis of the print orientation gives the results of the maximum tensile strength and compressive strength measured on the test pieces printed at the corresponding angles 22.5° and 67.5°. The pattern printed at 67.5° has the highest flexural strength, and the pattern printed at 0° has the highest impact strength and fatigue strength. In addition, the photopolymerization time factor is also an essential factor affecting the mechanical properties, including the elastic modulus, tensile strength, and critical deformation. This factor accounts for 73% of the mechanical properties of products created with the SLA 3D printing process.
