Stereolithography (SLA) 3D printing service
Scroll for more
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 |
| Minimum 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 Sterilizable and solvent safe Good material properties |
| Clear | Clear | 82D | Able to make clear parts with intricate features Not optically clear but perfect to let light pass through and achieve some |
| Rigid | White | 89D | Strong, stiff, and resistant to bending Soft matte white finish |
| Tough 2000 | Gray | 81D | Strong and sturdy Good for prototypes Resistant to bending |
| Tough 1500 | Medium Gray | 76D | Resilient rigid resin Good for stiff but pliable parts that spring back into shape |
| Elastic | Clear | 50A | Springy, bendable and stretchable Will return quickly to original shape |
| Flexible | Black | 80-85A | Dampening properties Good for cushioning and soft touch areas Stronger mechanical properties than Elastic |
| Durable | Translucent, Clear | Pliable, impact resistant, lubricious Ideal for high wear areas or rigid parts that need to be pliable | |
| White | White | Matte white Able to achieve precise details Good for general prototypes or aesthetic parts | |
| Black | Black | Matte black Able to achieve precise details. Good for general prototypes or aesthetic parts. | |
| Color | Select colors available | Color resin Able to achieve precise details Good for general prototypes or aesthetic parts Only available for production qty orders | |
| High temp | Translucent Orange | Detailed precise prototypes Able to withstand temperatures up to 238 °C |
Finishing/post-processing options
