Polymer product production relies on old-age molding techniques. Additive methods have not delivered meaningful alternatives to traditional processes — until now. Learn how Joseph M. DeSimone uses continuous liquid interface production, or CLIP, technology, which embodies a convergence of advances in software, hardware and materials to bring the digital revolution to polymer additive manufacturing.
Digital Manufacturing of Polymer Products: Convergence of Hardware, Software and Materials

CLIP uses software-controlled chemistry to produce commercial quality parts rapidly and at scale by capitalizing on the principle of oxygen-inhibited photopolymerization to generate a continual liquid interface of uncured resin between a forming part and a printer’s exposure window. Instead of printing layer by layer, this allows layerless parts to “grow” continuously from a pool of resin, formed by light.
Compatible with a wide range of polymers, CLIP opens major opportunities for innovative products across diverse industries. Previously unmakeable products are already manufactured at scale with CLIP, including the large-scale production of running shoes by adidas (Futurecraft 4D), mass-customized football helmets by Riddell, the world’s first FDA-approved 3D-printed dentures, and numerous parts in automotive, consumer electronics and medicine.
At Stanford, DeSimone and others are pursuing new advances including digital therapeutic devices in pediatric medicine, new multi-materials printing approaches, recyclable materials and the design of a high-resolution printer to advance novel microneedle designs as a potent vaccine delivery platform.
CLIP also creates valuable opportunities for product light-weighting and de-materialization, accelerated product design cycles and local-for-local manufacturing.
About the speaker
Joseph M. DeSimone is the Sanjiv Sam Gambhir Professor of Translational Medicine and Chemical Engineering at Stanford. He holds appointments in the Departments of Radiology, Chemical Engineering, Chemistry (by Courtesy) and the Graduate School of Business (by Courtesy).
Previously, he was a faculty member at UNC-Chapel Hill and NC State University. He is also co-founder, board chair and former CEO (2014-2019) of the additive manufacturing company Carbon.
DeSimone is responsible for numerous breakthroughs in his career in areas including green chemistry, medical devices, nanomedicine and 3D printing. He has published more than 350 papers and holds more than 200 patents. Additionally, he has mentored 80 students through doctoral degree completion, half of whom are women and members of underrepresented groups in STEM.
In 2016, DeSimone was recognized by President Obama with the National Medal of Technology and Innovation. He is also a member of all three branches of the U.S. National Academies (Sciences, Medicine and Engineering). DeSimone received his bachelor’s degree in chemistry from Ursinus College in 1986 and his doctoral degree in chemistry from Virginia Tech in 1990.
