Stereolithography

Definition

Stereolithography is a 3D printing technology that uses a laser to cure liquid resin into solid plastic, layer by layer, to create complex objects. This innovative process revolutionized manufacturing and prototyping by allowing for rapid production and intricate designs that were not possible with traditional methods. As a pivotal advancement in print media, stereolithography bridges the gap between analog printing techniques and digital fabrication, showcasing the evolution of print from Gutenberg's press to the modern digital age.
