What is the principle and applicable scenario of SLA stereolithography 3D printing?

Technical Q&A2026-06-08

SLA stereolithography: Ultraviolet light irradiates liquid photosensitive resin, curing layer by layer to form the part.

Applicable to: high-precision appearance parts, jewelry, dental models, anime figures, precision small parts, and micro-structure components.
Materials: various types of photosensitive resins (rigid, tough, high-temperature resistant, transparent, and flexible resins).
Features: high precision and smooth surfaces; finished products are relatively brittle, and most resins are not resistant to high temperatures and have average mechanical strength.
