New liquid based 3D printing up to 100 times faster than existing technologyMd Noman Siddique (Author) Published Date : Mar 19, 2015 11:47 IST
On stage at the TED conference in Vancouver, California-based Startup Carbon3D introduced liquid based 3D printing to the world.
Currently, 3D printing is based on spraying layer upon layer of material and slowly building up objects that takes hours.
Carbon3D's CLIP (Continuous Liquid Interface Production) technology uses light and oxygen to grow objects from a pool of resin, instead of printing them layer by layer.
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.
The technology allows ready-to-use products to be made 25 to 100 times faster than other methods and creates previously unachievable geometries that open opportunities for innovation not only in health care and medicine, but also in other major industries such as automotive and aviation.
By rethinking the whole approach to 3D 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 Joseph M DeSimone, professor of chemistry at University of North Carolina at Chapel Hill and CEO of Carbon3D.
If 3D printing hopes to break out of the prototyping niche it has been trapped in for decades, we need to find a disruptive technology that attacks the problem from a fresh perspective and addresses 3D printing's fundamental weaknesses, said Jim Goetz, Carbon3D board member.
Reports suggest that the printer is capable of creating objects that are not taller than 1 ft. and wider than 4 inches.
In addition to using new materials, CLIP can allow us to make stronger objects with unique geometries that other techniques cannot achieve, such as cardiac stents personally tailored to meet the needs of a specific patient, said DeSimone.
Since CLIP facilitates 3D polymeric object fabrication in a matter of minutes instead of hours or days, it would not be impossible within coming years to enable personalised coronary stents, dental implants or prosthetics to be 3D printed on-demand in a medical setting, DeSimone added.
