StereoLithography (SLA)
Produce Complex Geometries with Excellent Accuracy and Great Surface Finish.
High-Resolution Prototypes and End-Use Parts
StereoLithography (SLA) is the first choice for producing complex geometries with excellent accuracy and the best surface finish. InterPRO offers SLA ultra-high resolution and ultra-large SLA-printed parts with a choice of materials to meet your project needs.
StereoLithography works by focusing a UV laser onto a vat of photo-curable resin. As the laser draws a shape on the surface of the photopolymer, the resin solidifies and forms a single layer of the desired 3D object. The process repeats for each layer of the design until the 3D object is completed.
InterPRO’s SLA technology produces incredibly small and extremely large prototypes with incredible accuracy, utilizing a variable-diameter laser beam that refocuses every millisecond to define high-precision features. InterPRO offers many StereoLithography materials to choose from, including glass clear, high-impact strength, high heat-resistant and Class VI medical grade.
InterPRO StereoLithography Benefits & Applications
StereoLithography is the best 3D printing technology for producing highly clear parts, such as lenses and bottles. The strength and detail of SLA models make them the most popular choice for design verification, checking fit, highly detailed appearance models, and electronic housings, as well as patterns for RTV molding and casting. Very fast delivery is standard.
- Very fast delivery available
- Extremely accurate, high-resolution features
- Properties that mimic thermoplastic
- Excellent, smooth surface finish
- Ideal for secondary operations including nickel/chrome plating, EMI shielding, adding inserts, custom-painted textures and graphics
- Excellent clarity, great for flow testing and internal visualization
- Extremely popular for fit testing and functional testing
- Uniquely rigid materials available for wind tunnel testing and fixtures
- Widely used for metal investment casting patterns
- Thermoforming molds
- Fixtures for assembly
