Stereolithrography  

Stereolithography models are great for plastic models that require transparent parts, fine details, or a model that is directly castable in to a metal part.

  • GREAT FOR DIRECT CASTING OF MODELS

Selective Laser Sintering

SLS Models are great for fully functional durable plastic prototypes with highly complex geometries. Grown parts are tough and dimensionally accurate but have a rough surface finish

Model Considerations

SLS uses a heated bed of powdered plastic and a laser to create parts. The laser melts togeher layers of powdered plastic material fusing them togeher, before adding another layer of plastic and repeating the process.   SLS is unique because it does not require supports, the powdered plastic from the previous layer supports the next.

SLS

SLA uses a laser beam and a tank of liquid resin to produce parts.   The laser beam draws on the surface of a build platform that is immerse in resin, the light causes the resin to solidify layer by layer to create the model and its support structure.
