What is SLA 3D printing?
Stereolithography (SLA) is an additive manufacturing process that belongs to the Vat Photopolymerization family. It uses a UV laser to selectively cure a liquid photopolymer resin layer by layer.
SLA is widely regarded as one of the most accurate 3D printing technologies, capable of producing parts with extremely high dimensional accuracy and smooth surface finishes that resemble injection-molded parts. It is ideal for visual prototypes, master patterns for casting, and complex anatomical models.
Benefits of SLA
- Exceptional surface finish
- High dimensional accuracy
- Fine intricate details
- Wide range of resin properties
Capabilities
- Accuracy: ± 0.3% (min ± 0.3mm)
- Layer Height: 25 - 100 microns
- Ideal for small complex parts
- Isotropic parts
