Stereolithography (SLA)

Stereolithography (SLA) is the most widely used rapid prototyping technology, also known as optical fabrication, photo-solidification, solid free-form fabrication and solid imaging. The term “stereolithography” was coined in 1986 by Charles (Chuck) W. Hull, who patented it as a method and apparatus for making solid objects by successively “printing” thin layers of an ultraviolet curable material one on top of the other.


It can produce highly accurate and detailed polymer parts. It uses a low-power, highly focused UV laser to trace out successive cross-sections of a three-dimensional object in a vat of liquid photosensitive polymer
