Stereolithography (SLA)
Stereolithography (SLA) is our most popular rapid prototyping process. Agile runs a fleet of large platform SLA machines lead by our “Monster” iPro 9000XL building parts up to 59 in x 29 in x 21 in. The greatest advantage of the SLA process is the final look of the product. Parts built in SLA have a smooth finish much like end use plastic parts. Couple that with the high speed of SLA and you have our most popular prototyping process.
Agile offers the greatest selection of Stereolithography (SLA) materials, meaning we can mimic the material properties of your final product. In many cases we use SLA for low volume manufacturing. This is because the more parts you build in SLA, the less each part will cost (economy of scale), one of the many ways Agile’s expertise can save you money.
Agile is pleased to offer tool-less production of Casting Patterns for the foundry industry. Rapid production of small to large 3D printed casting patterns in both Stereolithography (SLA) with QuickCast patterns. Seamless patterns up to 30″ x 26″ x 22″ or larger if adhered together. Read a case study on the benefits of using SLA Quickcast Patterns versus traditional manufacturing. See a video highlighting our SLA Services

SLA is often considered the pioneer of the additive manufacturing processes, with the first production systems introduced in 1988 and patented by 3D Systems founder Charles (Chuck) W. Hull. The SLA manufacturing process utilizes a vat of liquid photopolymer resin cured by ultraviolet (UV) laser to solidify the pattern layer by layer to create or “print” a solid 3D model.
A UV laser beam is directed by a computer guided mirror onto the surface of the UV photopolymer resin. The model is built one layer at a time from supplied 3D CAD data.
The laser beam traces the boundaries and fills in a two-dimensional cross section of the model, solidifying the resin wherever it touches. Each successive layer is applied by submersion of the build platform into the resin as the part gradually develops and the platform descends into the liquid resin.
Once the model is complete, the platform rises out of the vat and the excess resin is drained. The model is then removed from the platform, washed of excess resin, and then placed in a UV oven for a final curing. After curing SLA parts are then ready for post processing as required by the specific application.
TOLERANCES
Building in layers of .004″ or less, most parts can be produced within .005″ or less on the X/Y/Z axis.
BUILD ENVELOPE
With the largest machine in the industry, our iPro9000 XL can handle parts up to 59″ x 29″ x 21″ in size.
BEST APPLICATIONS
SLA is best suited for fit & form tests, conceptual models, and parts requiring smooth surface finishes.
