Investigation of the accuracy of plastic gears manufactured by stereolithography

Abstract

The best-known additive manufacturing process is 3D printing, which is increasingly used to manufacture various machine components. Stereolithography is a 3D printing process where a photosensitive photopolymer resin is solidified using UV light. In this article, we investigate the accuracy of plastic gears made by SLA 3D printing. The aim of the research was to study gears manufactured using SLA printing technology with 0.8, 1, 1.5 and 2 mm module, to determine how the resulting gears differ from the initial geometry and how the manufacturing method affects the parameters of the gears.
