This new 3D printing technique is called CLIP Continuous Liquid Interface Production and dramatically reduces printing time, from hours to minutes
An innovation by Carbon3D (carbon3d.com), unveiled at the TED2015 event, could fly 3D printing into new and interesting sectors. Imagine you are in the operating room with a blockage of blood vessels. The surgeon generally uses a tube to get to the obstructed point, where he then inserts a stent, which is a cylindrical metal mesh structure that is introduced into the organs. Carbon3D has devised a solution to make a stent that is best suited to the human body. The idea to produce a biodegradable stent for use in surgical operations explained Joseph DeSimone, CEO and co-founder of Carbon3D as well as professor of chemistry at the University of North Carolina at Chapel Hill and at North Carolina State University. The potential of this invention in the medical field it includes a completely innovative approach in the use of 3D printing.
The DeSimone team wants to find new roads and new application sectors, from medical to automotive, through objects for Hollywood films. The technology developed by Carbon 3D is called Continuous technology Liquid Interface Production-go (CLIP) and works by exploiting the power of light and oxygen to transform the photosensitive resin into a finished object. Instead of printing the layer-by-layer the object, which unfortunately occurs at an extremely slow speed, this new photosynthetic light diaprocess resin, and takes oxygen as inhibiting agent, to print the object in 3d. So the oxygen can create a 'dead zone' between the layer and layer of the resin in print that is small in tens of microns (about the diameter of 2-3 red blood cells). In this subsection of the resin, it is impossible for photopolymerization to take up space . The machine will then produce a series of cross-sectional images with UV light in a manner very similar to a sequence of frames from a motion picture film. The process will be 25 to 100 times faster than before. This technology could open the doors to new markets.Cecilia Candatore
