Abstract


This study aims to investigate the geometry scale effect and printing orientation on the tensile properties of common photosensitive resins produced via stereolithography (SLA). Through tensile tests, the research evaluates how variations in part size and orientation on the build-platform influence mechanical performance, with a particular focus on challenges in scaling SLA technology for practical applications. By analyzing the interaction between printing parameters relative to tensile forces and resulting mechanical properties, this study provides insights into optimizing SLA processes for enhanced tensile strength and stiffness. The results contribute to understanding how SLA can evolve from prototyping to reliable production of functional parts, offering supplementary insights in additive manufacturing.
