Stereolithography (SLA)

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 houses Formlabs Form 3 SLA printers. 

Producing parts with SLA

Build volume

• 145 x 145 x 185 mm

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.
