What are the Benefits of Stereolithography?

  • SLA Applications

    Tolerances on SLA parts are typically less than 0.05 millimeters, making it an excellent choice when precision is your top priority. Delivering the smoothest surface finish of any additive manufacturing process, the quality of SLA parts makes this  versatile technology great for:

SLA Material Properties & Uses

3D Systems’ Accura® SLA resins are the industry’s gold standard for accuracy, providing excellent resolution, surface finish and dimensional tolerances

SLA materials are available for parts requiring similar characteristics to injection-molded ABS or polypropylene such as snap-fit assemblies, automotive styling components, and master patterns, and for higher-temperature applications and exceptional clarity. Biocompatible materials are available for a wide range of medical applications, such as surgical tools, dental appliances, and hearing aids. Other materials are specifically formulated for investment casting patterns, offering low ash creation and high accuracy while also being expendable.
