The most common technique of 3D printing is stepwise horizontal layer-by-layer approach to fabricate 3D objects, which is very time consuming and is the same process used by most commercial 3D printers in the market. A team of researches led by Joseph DeSimone, a chemist at University of North Carolina and CEO of Carbon3D, invented Continuous Liquid Interface Production (CLIP) technique that can print 3D objetcs from liquid resin at game-changing speeds. Check this cool video of printing a 3D Eiffel Tower model using this approach.
Traditional 3D printing requires a number of mechanical steps, repeated over and over again in a layer-by-layer approach. CLIP is a chemical process that carefully balances light and oxygen to eliminate the mechanical steps and the layers. It works by projecting light through an oxygen-permeable window into a reservoir of UV curable resin. The build platform lifts continuously as the object is grown.
