Stereolithography
Stereolithography (SLA) is an additive manufacturing process that uses a UV laser to cure liquid photopolymer resin layer by layer to create 3D objects. It is one of the earliest and most precise 3D printing technologies, known for producing high-resolution, smooth-surfaced parts suitable for prototyping, modeling, and small-batch production. The process involves a build platform submerged in a resin tank, with the laser tracing cross-sections to solidify each layer.
Developers should learn or use stereolithography when creating detailed prototypes, intricate models, or functional parts that require high accuracy and fine features, such as in product design, dentistry, or jewelry making. It is particularly valuable for rapid prototyping in industries like aerospace and automotive, where precision and surface finish are critical, and for producing molds or master patterns for casting processes.
