Stereolithography (SLA)

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 houses Formlabs Form 3 SLA printers.

Producing parts with SLA

General process information

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.

Materials

Material	Color	Hardness (post-cure)	Description
Surgical guide	Clear orange	67D	• Biocompatible
Clear	Clear	82D
Rigid	White	89D	• Strong and brittle • Meant for more industrial applications
Tough 2000	Gray matte	81D	• Engineering resin • For mechanical and industrial applications
Tough 1500	Gray matte	76D	• Engineering material • More flexible than Tough 2000
Elastic	Clear	50A	• Elastomeric
Flexible	Black	80-85A	• Flexible • Stronger mechanical properties than Elastic
