Stereolithography: Principles and Applications

This lecture covers the principles and applications of stereolithography (SLA) in additive manufacturing. SLA involves building 3D parts layer by layer from a photoresist, consolidated by a UV laser. It discusses the etymology, equipment, resolution, build speed, mechanical properties, and companies involved in SLA. The lecture also explores the cost comparison between SLA and injection molding, the use of SLA in manufacturing small series and custom items like hearing aids, and the importance of support structures in the SLA process.
