News flash, there’s more than one way to skin a cat, and 3-D print objects:
The technology, called CLIP — for Continuous Liquid Interface Production — manipulates light and oxygen to fuse objects in liquid media, creating the first 3-D printing process that uses tunable photochemistry instead of the layer-by-layer approach that has defined the technology for decades. It works by projecting beams of light through an oxygen-permeable window into a liquid resin. Working in tandem, light and oxygen control the solidification of the resin, creating commercially viable objects that can have feature sizes below 20 microns, or less than one-quarter of the width of a piece of paper.
“By rethinking the whole approach to 3-D printing, and the chemistry and physics behind the process, we have developed a new technology that can create parts radically faster than traditional technologies by essentially ‘growing’ them in a pool of liquid,” said DeSimone, who was scheduled to reveal the technology at a TED talk on March 16 in the opening session of the conference in Vancouver, British Columbia.
