A model of a skull created for use in a medical study using cutting-edge, 3-D printing technology at the National Center for Rapid Technologies (RapidTech). The model was created on a 3-D printing machine equipped with a stereolithography apparatus (SLA), one of several methods used to create 3-D-printed objects.
Instead of extruding ink or some other liquid onto a surface, such as with an inkjet printer, SLA machines begin with an excess of liquid plastic, some of which is cured, or hardened, to form a solid object.Image credit: RapidTech
