OVERVIEW

    Faster to Market

    Stereolithography (SL, SLA) is the original 3D printing process still widely used today for its accuracy and speed. Fast build and delivery reduces the design, engineering and test phases of product development and allows you to get to market faster.

    Capabilities

    Stereolithography is often used for prototypes, master patterns or large concept models, form and fit prototypes and investment casting patterns. SL offers virtually limitless part size; we can seamlessly bond individual sections into industrial sized patterns.

    ID-Light

    Build extremely light, large-scale parts in record time with our exclusive hollow build method, ID-Light. Ideal for nonstructural appearance models, ID-Light builds faster, weighs less and costs less than solid SL models. Parts built with ID-Light are lighter and have a better as-built surface than 10-20 pound foam.

    Iterate Faster

    The design freedom and speed of Stereolithography makes design changes, iteration and validation easier than ever.

    BUILD

    Reliable Resins

    Stereolithography builds parts with a precise UV laser to cure and solidify thin layers of a photo-reactive resin. Post-build, SL parts require some support material removal and UV curing, as well as hand finishing or other requested post-processing.

    Finishing Experts

    Our finishing expertise takes your 3D printed prototype and transforms it into a replica of your finished product. Any surface look is achievable with our expert finishers. Custom finishing, texture, color, artwork, EMI/RFI shielding, plating and other functional coatings can bring additional value to prototyping and models.

    SL Photopolymers

    Our wide range of Stereolithography photopolymers serve our customer’s requirements, from clear to strong, rigid plastics to special formulas for investment casting patterns.

    FAQ's

    Frequently Asked Questions

    What level of detail can be obtained with SL?

    Stereolithography is available in a variety of resolutions. At its finest resolution, the layer thickness is 0.002” and the X/Y resolution is 0.004”.

    Can SL-made components function as production parts?

    Stereolithography is not generally considered suitable for production applications because the photo-reactive resins used in the process do not remain stable under long exposure to UV light. However, SL is often used to make precise investment casting patterns to create end-use metal parts.

     

    stereolithography

    “With 3D printing, I’m able to send a model to Stratasys Direct Manufacturing and have it in-hand within days, and that allows me to perform a new test so much faster. We don’t have these kinds of prototyping capabilities in-house, so having this ability in three days versus the six weeks it would normally take with conventional means makes our iterative design process much faster.”

    How it Works: Stereolithography

    “In the old days, when we prototyped, it would take a machinist sometimes 6-8 weeks to make a simple pump housing. I can do that in 6-8 hours. That’s what it does.”
