Stereolithography: Basics & Applications

This lecture covers the basics of stereolithography, where a 3D part is built layer by layer from a photoresist using UV light. It explains the principles of consolidation, the role of galvanometric mirrors, and the etymology of the term. The lecture also discusses the resolution of additive processes, build speed considerations, mechanical properties of parts, and the companies involved in stereolithography. Additionally, it explores micro-stereolithography for producing very small parts, cost comparisons between SLA and injection molding, and the advantages and applications of stereolithography. The disadvantages and issues related to the technique, such as material limitations, aging effects, and post-processing requirements, are also addressed.
