SLA – Stereolithography

A 3D printing technology that uses a UV laser to cure liquid resin layer by layer into solid parts. Known for its high precision and smooth surface finish, SLA is ideal for producing detailed prototypes, models, and functional components with intricate features. It's widely used in industries such as dentistry, jewelry, and product design.

SLA Layer Thickness Options

Layer height refers to the thickness of each individual layer in a 3D print. Thinner layers produce smoother, more detailed prints but take longer. Thicker layers print faster but result in a rougher surface with less detail. Choosing the right layer height depends on the part’s required balance between quality and production time.

Rapid – 100 µm

A thicker layer option that speeds up printing times while still delivering reasonable detail.

Standard – 50 µm

A balance between detail and speed.

Fine – 25 µm

The finest layer thickness available, providing the highest detail and smoothest surface finish.

SLA Print Resolution Options

SLA Resolution defines the level of detail and surface smoothness in a print.

Standard

Offers reliable quality for prototypes and functional parts, with a balanced level of detail and surface smoothness, suitable for most applications.

High

Delivers exceptional precision and fine details, ideal for intricate models, complex geometries, and parts requiring a smooth, polished finish.

Custom Finish

Tailor your FDM 3D-printed parts with a finish that meets your needs. Specify your preferred finish, such as sanding for a smooth surface, sealing for durability, or assembly and joining for multi-part projects.
