Stereolithography 3D Printing

SLA 3D Printing

One of the most tried, tested & efficient 3D printing technologies. Stereolithography cures resin layer-by-layer using a laser.

Cost-effective | Lead times from 1 day | High-quality

What is SLA 3D Printing?

Stereolithography 3D printing uses a CAD file to build a part layer by layer from UV-sensitive resin being cured by a laser.

A wide selection of materials with different properties are used within resin 3D printing. It is one of the most popular technologies for additive manufacturing.


  • High resolution.
  • Quick print times.
  • Smooth surfaces.
  • Can print transparent parts.
  • Can print large parts.
  • Can print complex geometries.


  • Medical devices.
  • Visual prototypes.
  • Housings.
  • Transparent assemblies such as headlights, bottles etc.
  • Masters for rapid prototyping.
