The Technology, called Continuous Liquid Interface Production (CLIP), manipulates light and oxygen to fuse objects in liquid media. It works by projecting beams of light through an oxygen-permeable window into a liquid resin to rapidly transform 3D models into physical objects.
Working in tandem, UV light, which triggers photo polymerization, interacts with oxygen, which inhibits the reaction, to 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. This is the first 3D-printing process that uses tunable photochemistry instead of the layer-by-layer approach that has defined the Technology for decades.
Faster, stronger, predictable
CLIP enables a very wide range of materials to be used to make 3D parts with novel properties, including elastomers, silicones, nylon-like materials, ceramics and biodegradable materials, and could allow for synthesizing novel materials that can advance research in materials science.
Conventionally made 3D printed parts are notorious for having mechanical properties that vary depending on the direction the parts were printed because of the layer-by-layer approach. Much more like injection-molded parts, CLIP produces consistent and predictable mechanical properties, smooth on the outside and solid on the inside, the company says.
“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-Chapel Hill and of chemical engineering at North Carolina State and CEO of Carbon3D, who co-invented the method.
It’s not difficult to get excited when you look at the pace of technological innovation. The above invention has been featured on CNBC with someone attempting to print an AR-15 which shows the negative connotations of the development. Setting that example aside, this represents an important step towards having a practical tool in one’s home but there are more important considerations from an investment perspective.
