Stereolithography (SLA) 3D Printing Service
Is your part file ready to go?
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
General process information
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. |
Materials
