3D printing with Stereolithography (SLA) | Stratasys Direct

Precision and Versatility with Stereolithography

Stereolithography (SLA) is a 3D printing technique that uses a laser to cure liquid resin layer-by-layer, building precise prototypes and even functional end-use parts.​ Stereolithography is most commonly used as a prototyping technology within industries that need to print parts or models to validate fit form and function or for concept visualization.  Stereolithography is also used in manufacturing applications for short-run part production such as vacuum castings, injection mold tooling, investment casting master patterns and functional end-use part production for certain environments.

From one-off prototypes, to low-volume production, we have the experience and engineering know-how to support you

What is Stereolithography?

Stereolithography (SLA) is a vat polymerization 3D printing process and is the original 3D printing process that is still widely used today for its accuracy and speed. SLA is often used for prototypes, large concept models, and lightweight display models. 

Stereolithography can create high dimensional accuracy parts with intricate designs and smooth surfaces. It also allows us to print watertight components in clear materials making it easy to test fluid flow found in product designs. 

At Stratasys Direct we can build extremely light, large-scale parts in record time utilizing our sparse fill, which is a hollow build method. Sparse fill is ideal for nonstructural appearance models. These parts build faster, weigh less and cost less than solid SLA models. 

How Sterolithography (SLA) Works

Stereolithography (Monikers: Vat photopolymerization, photocuring, SLA, SL) relies on a precise UV laser to cure liquid resin layer by layer. Its build platform sits just below the top of the resin bath. The build platform is coated with a thin layer of liquid plastic.

A UV laser hits dynamic mirrors which direct the UV energy downwards across the build platform, curing the liquid resin in precise patterns one cross-section at a time. After each layer is cured, the build platform retracts into the bath of liquid while a recoater blade evenly distributes the resin across each new layer.

Stereolithography also requires build supports which are removed manually by hand, meaning areas that require support be accessible. Stereolithography support material is the same material as the final part.

During printing, the resin within the chamber can become trapped within the part or pool in certain part features, reabsorbing into the part and causing bloating and design distortion. Therefore, after a build is complete, excess resin is drained and supports are removed.

Unlike PolyJet, Stereolithography parts do not fully cure during the build so the parts enter a UV oven to complete curing. Expertise comes from experience, and being that Stratasys Direct has been building SLA parts almost since the industry's birth means that we know exactly how to build and post-process SLA exactly to your needs.
