Ultra-high detail resin printing for prototypes, dental models, jewelry casting, miniatures, and precision parts. Find SLA and MSLA print shops near you.

The difference in surface quality is obvious the moment you hold the part: smooth enough to skip sanding, fine enough to resolve features an FDM machine would blur into noise. That's why SLA dominates dental labs, jewelry studios, and any application where a prototype needs to look finished on day one.
Most professional bureaus now run MSLA or DLP rather than traditional laser-based SLA — the light source covers an entire layer at once, which dramatically cuts print times without sacrificing resolution. From a practical standpoint, the output quality across all three variants is similar. What varies is build volume, cost, and which resin formulations a specific shop carries.
Produce smooth, accurate prototypes that look and feel like finished products — ideal for investor presentations and design reviews.
Dental resins produce high-accuracy models for aligners, crowns, and surgical guides. Used widely by dental labs.
Castable resin burns out cleanly for lost-wax casting. Ideal for custom jewelry, rings, and intricate ornamental work.
Tabletop gaming miniatures, collectibles, and figurines with exceptional surface quality and fine detail.
Tough and engineering resins replicate ABS and polycarbonate properties for functional testing.
Eyewear, hearing aids, wearables, and consumer electronics housings benefit from SLA's surface finish.
SLA produces far smoother surfaces and finer detail than FDM printing, but parts are generally more brittle and build volumes are smaller. For structural functional parts, SLS nylon printing is often a better fit. For metal components, see metal 3D printing.
