Noun
stereolithography (uncountable)
A means of rapid prototyping in which a laser hardens successive layers of a photopolymer to create a part with a shape defined by a computer model.
Several forms of 3D printing —including layer-by-layer stereolithography and two-photon absorption 3D photopolymerization —use photopolymerization. Source: Internet
The designs are then prototyped using an in-house stereolithography machine. Source: Internet
