SLA 3D printing service — smooth finish, fine detail, fast delivery.
SLA (stereolithography) is the 3D printing technology of choice when surface finish and dimensional precision matter more than raw toughness. We run desktop and Industrial SLA with 14 resin options — from Standard for visual models to Tough 2K for snap-fit validation to High Temp for thermal testing.

When to choose SLA
The smoothest surface finish in our catalog — 25μm layers are virtually invisible. Ideal for client reviews, photo shoots, and investor samples.
Tight dimensional tolerances and crisp features let you test how parts actually mate before committing to injection mold tooling.
Lattice structures, textured surfaces, small logos, and precision features that FDM cannot resolve. SLA captures what your CAD actually shows.
Optical Clear resin delivers see-through parts for lighting prototypes, fluidics, and transparent housings. Frosted and tinted options available.
Specialty SLA resins
Withstands up to 238°C HDT. Ideal for mold masters, heat-exposed prototypes, and thermal fixtures.
Shore 50A to 80A elastomers for soft-touch prototypes, gasket validation, and wearable device bands.
Burns out cleanly in investment casting patterns. Zero ash residue.
Glass-filled, dimensionally stable under load. Replaces machined thermoset prototypes for fraction of the cost.

Related Comparisons
FDM vs SLA — which 3D printing technology is right for your part?
Choose FDM when cost and speed matter most, or when you need tough engineering thermoplastics (PETG, ASA, PC CF) at larger build volumes. Choose SLA when surface finish, dimensional accuracy, or fine detail resolution is the priority — visual prototypes, snap-fit validation, and presentation models.
SLA vs MJF — precision and finish vs production-grade strength.
Choose SLA when surface quality and dimensional precision are the priority — client presentations, snap-fit prototypes, and parts that need painting. Choose MJF when mechanical performance and batch consistency matter — production parts, functional testing, and parts that ship to customers.
Resin vs filament 3D printing — SLA vs FDM for real-world parts.
Choose resin (SLA) when surface finish, dimensional precision, or fine detail resolution are the priority — visual prototypes, snap-fit validation, jewelry patterns, dental models. Choose filament (FDM) when part toughness, cost, build volume, or material breadth matters more — functional prototypes, jigs, outdoor parts, and large structural builds.
