ChemBE Seminar Series: Joseph M. DeSimone

Description

Joseph M. DeSimone, a professor of translational medicine and chemical engineering at Stanford University, will give a talk titled "Continuous Liquid Interface Production (CLIP): 3D Printing at the Intersection of Materials, Process and Design" for the Department of Chemical and Biomolecular Engineering. DeSimone holds appointments in the Stanford departments of Radiology and Chemical Engineering with courtesy appointments in the Department of Chemistry, the Department of Materials Science and Engineering, and Stanford's Graduate School of Business.

Abstract:

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.
