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
Our Accura SLA resins offer the most accurate fit/form prototypes for design verification before committing to production. High accuracy and excellent surface finish makes these resins the preferred choice for designer models, engineering verification, and master patterns for silicone and rubber molds.
SLA materials are available in a wide range of mechanical properties and can produce parts with characteristics similar to injection-molded ABS or polypropylene, suitable for applications such as snap-fit assemblies, automotive styling components, and master patterns, as well as higher-temperature applications and exceptional clarity. SLA materials for higher-temperature applications and clear materials with polycarbonate-like properties are also available. Our SLA material portfolio also includes biocompatible materials suitable for a wide range of medical applications such as surgical tools, dental appliances, and hearing aids. Other SLA materials have been specifically formulated for sacrificial investment casting patterns, offering low ash creation and high accuracy, while also being expendable.
Stereolithography 3D Printers
We offer an integrated additive manufacturing solution for SLA including hardware, software, and materials, fine-tuned to achieve the gold standard in surface finish and accuracy. The edge definition, tolerances, and accuracy of our SLA parts rival machined or molded plastic parts.
Our SLA resin 3D printers offer a range of build volumes and price points.
Why Use Stereolithography?
Unrivaled Accuracy and Precision
SLA 3D printers are able to deliver highly detailed, tiny parts just a few mm in size, all the way up to 1.5 m long parts—all at the same exceptional resolution and accuracy. Even large parts remain highly accurate from end-to-end, with virtually no part shrinkage or warping.
3D Systems has released 21 different SLA printers over the last 3 decades, each providing significant improvements over the previous version, offering you exceptional part quality. Our customers do not have to compromise speed or feature detail because we utilize two laser spot sizes per layer—delivering the best surface finish, small feature definition, and throughput.
Broad SLA Materials Selection
By working with our customers over the last 30 years, 3D Systems has supported more than 80 SLA additive manufacturing materials, tuned to application needs. Find the mechanical specifications you need in our existing portfolio, or talk to our experts to find what you're looking for.
Get the highest productivity possible with the fastest print technology for large and production runs. Quick interchangeable material delivery modules keep machines running to advance your part manufacturing workflow, while 3D Connect™ Service offers proactive and preventative support.
