Stereolithography (SLA)

Definition

Stereolithography (SLA) is a form of additive manufacturing that uses ultraviolet (UV) light to cure liquid resin into solid plastic layer by layer, creating three-dimensional objects. This technology is significant in additive manufacturing because it allows for the rapid production of complex geometries and detailed designs, making it an ideal tool for prototyping and even functional parts in various industries, including biomimicry applications that draw inspiration from nature's designs.

5 Must Know Facts For Your Next Test

1. SLA is known for producing high-resolution parts with smooth surface finishes, making it suitable for intricate designs that require precision.
