Stereolithography (SLA) 3D Printing Service

Is your part file ready to go?
Want to talk about your project?

SLA is a type of photopolymerization capable of producing parts with an excellent surface finish and small feature resolution. While SLA is not typically suitable for high-performance applications, its intricate and accurate detailing make it a popular option for prototypes. Our factory uses Formlabs Form 3 SLA 3D printers.

Producing parts with SLA

Build volume

• 335 × 200 × 300 mm
• 13.2 × 7.9 × 11.8 in

Min. feature size

• The minimum feature size is different for each resin, but we are able to achieve complex and aggressive geometry.

Lead time

• Get your prototypes in as little as seven days. Production or high volume runs will be examined on a case by case basis.
