What’s in a name? Thoughts on Stereolithography terminology

Leslie's Blog

While speaking to attendees at the Additive Manufacturing Users Group recently, I observed that the term SLA® has become synonymous with a range of additive manufacturing processes that use a UV light source to cure, layer by layer, a photopolymer formulation to translate a Computer Aided Design (CAD) into a three-dimensional part. Is it important to make a distinction between SL and SLA as a descriptor of the stereolithography process? Support requirements can vary by process.
