Stereolithography (SLA)
Design Processes
3D printing technique using a liquid resin cured by a UV laser.
In practice
Stereolithography (SLA) is an additive manufacturing process that uses a laser to solidify liquid resin, layer by layer, to create precise 3D objects. SLA is commonly used for producing high-resolution prototypes and detailed models with smooth surfaces. This technology is valued for its accuracy and ability to create intricate designs, making it a preferred choice in various industries for prototyping and small-scale production.
Questions
What is Stereolithography (SLA)?
Stereolithography cures liquid photopolymer resin with a light source, layer by layer, producing parts with very fine detail and smooth surfaces.
Why do you use Stereolithography (SLA)?
It gives the highest resolution of the common printing processes, which makes it the choice for appearance models and fine features.
How do you use/apply Stereolithography (SLA)?
Orient to minimise supports on visible faces, print, then wash and post-cure. Resin parts are brittle and degrade in sunlight.
When do you use Stereolithography (SLA)?
For appearance prototypes, master patterns and fine mechanical detail.
Who uses Stereolithography (SLA)?
Industrial designers, jewellers, dental and medical manufacturers.
