What is Stereolithgraphy?
Stereolithography (SLA) is a 3D printing process used to create concept models, cosmetic prototypes, and complex parts with intricate geometries. It's an additive manufacturing technology that forms parts by curing thermoset resin with a UV laser. A wide selection of materials, extremely high feature resolutions, and quality surface finishes are possible with SLA.
SLA 3D printing is primarily used for:
- parts requiring high accuracy and features as small as 0.002 in.
- good surface quality for cosmetic prototypes
- form and fit testing
SLA Design Guidelines and Capabilities
Our basic guidelines for stereolithography include important design considerations to help improve part manufacturability, enhance cosmetic appearance, and reduce overall production time.

Surface Finish Options for SLA Parts
| |
| Unfinished | Dots, or standing"nibs," remain evident on the bottom of the part from the support structure remnants. Good for when fast lead times are required or cost is a factor |
| Natural | Supported surfaces are sanded down to eliminate the support nibs. |
| Standard | Supported surfaces are sanded, and the entire part is finely blasted for a consistent look. Note that the layers are still present. |
| Custom | Soft-touch paint, clear part finishing, painting, masking, color matching, decals/graphic, and texture finishes are available. |

Metal Plating
Our metal-plating process for SLA coats OLA 8300 (Rice-yellow) with nickel, giving parts the look, feel, and strength of metal, but without the weight. The combination of the material's strength, rigidity, and temperature resistance with nickel plating takes strength, stiffness, and impact and temperature resistance to a degree previously unattainable in SLA parts.
Microfluidics
Our microfluidic fabrication process is a modified form of high-resolution SLA that uses Transparent Photopolymer Resin. Parts are resistant to water and humidity, and work well for lens and flow-visualization models.
