Introduction to Stereolithography (SLA)
Stereolithography (SLA) is a 3D printing technology that uses a liquid resin cured by ultraviolet (UV) light to create three – dimensional objects layer by layer. It is one of the earliest and most precise 3D printing methods, offering high – resolution parts with smooth surface finishes. SLA is widely used in various industries such as aerospace, automotive, medical, and consumer products for prototyping, tooling, and small – batch production. Stereolithography (SLA)
