SLA, short for stereolithography, is a 3D printing process where an UV laser creates layer after layer by selectively curing and solidifying a photopolymer resin.
SLA is one of the most common and precise techniques for 3D printing, known for its accuracy and high level of detail. This technology supports a variety of materials, including both rigid and flexible plastics, making it suitable for various industries such as medicine, dentistry, optics, and prototype development.
The technique involves light projection, typically from a UV laser, onto a liquid containing a photopolymer. When exposed to the light, the polymer liquid cures and solidifies. A platform is subsequently lowered into the liquid, which the cured polymer sticks to. After each layer, the platform is raised a small increment, and the process is repeated layer by layer until the entire object is constructed. After printing, any uncured resin residues are washed away in a Form Wash L-washer and then post-cured in a Form Cure L-curing oven (machine-dependent).
One of the significant advantages of SLA is its precision and high resolution. Although it is possible to create large batches using SLA, it is not the most cost-effective technique for that purpose. Nevertheless, it remains one of the most widely used techniques for 3D printing.
The Application Center for Additive Manufacturing possesses a Form 3L from Formlabs.
