“3D printing” is a misnomer: it is actually 2D printing over and over again. This lecture will describe a new advance in 3D additive manufacturing that is rapid, continuous and no longer layer-by-layer that promises to advance industry beyond basic prototyping to 3D manufacturing. The new Continuous Liquid Interface Production technology (CLIP) harnesses light and oxygen to continuously grow objects from a pool of resin instead of printing them layer-by-layer. The technology was simultaneously introduced to the scientific community as the cover story in the journal Science and on the stages of TED2015. CLIP technology raises the state-of-the-art in 3D fabrication in three ways:  game-changing speed - 25-100 times faster than conventional 3D printing; commercial quality - produces objects with consistent mechanical properties; material choice - enables a broad range of polymeric materials, and microfabrication - enables complex geometries to be fabricated in the tens of microns size scale.<br/>This lecture will introduce CLIP and will describe the opportunities associated with it, including the potential for designing new approaches to medical and drug delivery devices.
