How Stereolithography Works

Stereolithography (SLA) is an advanced 3D printing process used to manufacture prototypes and parts quickly and with high accuracy. This method works by using a laser-based system that builds parts, layer by layer, using a photosensitive epoxy-based polymer. Once the model has been printed, it’s cured with UV light to solidify the resin material and strengthen its structure. SLA machining offers an efficient way to produce accurate parts with quality surface finish and adequate mechanical properties.

Here’s how our SLA solutions can help you:

  • Produce high precision, quality 3D models with fine details and complex geometries faster and more cost-effectively.
  • Accelerate design processes for just about any part: form/fit models, mechanical models, master patterns for cast urethane, etc.
  • Create quality surface finishes using a variety of paints and textures for highly-cosmetic show models.
  • Eliminate the need for hazardous filaments and powders for more eco-friendly additive manufacturing.

Our Stereolithography Capabilities

Stereolithography is one of the most popular 3D printing technologies in additive manufacturing because it’s a fast, affordable way to build extremely high-resolution parts for rapid prototyping and end-use, low-volume runs. Our SLA capabilities offer unmatchable speeds with the quality you need for a wide range of detailed prototyping applications.

High Accuracy
