Summary
Stereolithography (SLA), a vat photopolymerization-based additive manufacturing process, employs ultraviolet (UV) light to selectively cure liquid resin into solid layers with exceptional precision (±25 μm) (Formlabs, 2024). Unlike extrusion-based methods such as FDM, SLA achieves superior surface finishes (Ra <0.5 μm) and dimensional accuracy, making it ideal for applications requiring intricate geometries and smooth surfaces. Furthermore, advancements in resin chemistry have expanded SLA's material portfolio, with formulations now offering optical clarity comparable to PMMA, tensile strengths rivaling ABS (up to 55 MPa), and heat deflection temperatures exceeding 200°C. These material innovations, combined with declining equipment costs, have enabled SLA to transition from prototyping to end-use production across various industries.
