Continuous Liquid Interface Production (CLIP): 3D Printing at the Intersection of Materials, Process and Design: Nano Seminar series
November 4 @ 2:00 pm - 3:00 pm
Prof. Joseph M. DeSimone, Stanford University, ChemE & MSE & Business
The production of polymer products relies largely on age-old molding techniques. A major reason for this is that additive methods have not delivered meaningful alternatives to traditional processes—until now. In this talk, I will describe Continuous Liquid Interface Production (CLIP) technology, which embodies a convergence of advances in software, hardware, and materials to bring the digital revolution to polymer additive manufacturing.
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’ 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, we 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 technologies in the microelectronics and drug/vaccine delivery areas, including novel microneedle designs as a potent vaccine delivery platform.
Joseph M. DeSimone did his PhD in Chem at VA Tech, founded the Institutes for Advanced Materials and for Nanomedicine at UNC Chapel Hill, moving to Stanford in 2020. Awards include the Lemelson-MIT, the Exner Medal and many many others: he is one of only 25 individuals elected to all three branches of the U.S. National Academies (Sciences, Medicine, Engineering) He was also co-founder and CEO of 3D printing company Carbon, Inc.
