Design Guide: Stereolithography (SLA) 3D Printing

SLA 3D printing is a highly-versatile platform for making custom parts in prototype and production settings; often acting as a stand-in for injection molded plastic parts. Learn how you can apply SLA to your next project with our free guide.

SLA

SLA is an additive manufacturing process that focuses an ultraviolet (UV) light on a vat of photopolymer resin. It offers higher resolution printing than many other 3D printing technologies, allowing customers to print parts with fine details and surface finishes. SLA 3D printing is a highly-versatile platform for making custom parts in prototype and production settings; often acting as a stand-in for injection molded plastic parts.

About Xometry

Stereolithography (SLA) is a powerful 3D printing technology that produces extremely accurate and high-resolution parts that are capable of being used directly in end-use, low-volume production, or for rapid prototyping.  Stereolithography 3D printing is a highly-versatile platform for making custom parts in prototype and production settings, often acting as a stand-in for injection-molded plastic parts.

Xometry offers both standard and high-resolution options for fine detail parts, and can also print larger sized parts and products, offering up to a 29" inch build area. In addition, Xometry's manufacturing partner network allows us to offer a larger variety of materials than other 3D printing companies - we offer a wide range of both Accura and Somos brand materials.
