StereoLithography

Stereolithography (often called SLA or SL) rapidly builds components using a precise UV laser to cure and solidify thin layers of a photo-reactive resin. One of the most accurate 3D printing technologies, SL is ideal for concept models, form and fit studies, and investment casting patterns. We offer a suite of professional finishing options to achieve a high-quality surface finish. In addition, we can join multiple sections of a part design quickly and seamlessly to create large parts.

BENEFITS of Stereolithography

Large Geometries

Don’t sacrifice accuracy for size. Stereolithography offers virtually limitless part size. We will seamlessly bond individual sections into industrial sized patterns.

Finishing Options

Your parts will be delivered on time and ready for immediate integration with our complete suite of finishing services. Backed by expert painters and technicians with years of experience, we offer hand finishing, texture, non-cosmetic and cosmetic paint, as well as EMI and RFI shielding and plating options

Stereolithography (SL) APPLICATIONS

SL is often used for prototypes or large concept models that require coatings or finished surfaces and smooth master patterns.

Common applications include:

Anatomical models
Lightweight concept models
Architectural models
Urethane casting patterns
Large investment cast patterns

Stereolithography Materials

Look to SL to mimic properties of ABS, polycarbonate, and polypropylene in layers as thin as 0.0508mm”.
We have a wide range of resins for every prototyping need – from clear to strong, rigid plastics
and a resin specifically formulated for investment casting.

Stereolithography: Frequently Asked Questions

What level of detail can be obtained with SL?

Stereolithography is available in a variety of resolutions. At its highest resolution, the layer thickness is 0.0508mm and the X/Y resolution is 0.1016mm.

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.

Prepare Your STL for 3D Printing

Stereolithography requires an STL file. For detailed CAD specifications and considerations for preparing your STL file for 3D printing,
