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 |
