Stereolithography (SLA).
Stereolithography (SLA).
Stereolithography (SLA) is the first commercialized 3D printing technology, invented by 3D Systems' Co-Founder and Chief Technology Officer Chuck Hull in the 1980s. It uses an ultraviolet laser to precisely cure photopolymer cross-sections, transforming them from liquid to solid. Parts are built directly from CAD data, layer-by-layer into prototypes, investment casting patterns, tools, and end-use parts. Once the SLA printing process is complete, SLA parts are cleaned in a solvent solution to remove any residual uncured resin from the part surface.
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.
Delivering the smoothest surface finish of any additive manufacturing process, the quality of SLA parts makes this versatile technology great for:
- Master patterns for vacuum casting
- Sacrificial patterns for metal casting
- Tools, molds and dies
- Functional prototypes and models
- High clarity, transparent products and components
- Complex assemblies
- Wind tunnel models
- Under the hood components
- Rapid production of flow test rigs
- Mass customization
- Custom assembly jigs and fixtures
