Rapid printing of multimaterial objects by injection continuous liquid interface production
Date
March 20, 2022
Continuous liquid interface production (CLIP) is a revolutionary approach to additive manufacturing (AM) that has begun to elevate the fabrication method from prototyping to production. However, significant limitations on the process derived from mass transport issues have, to date, limited printable areas at high speeds and the viscosity of resins used; moreover, printing with composites and multiple materials at once has been heretofore impossible. Here, we investigate the fundamental mass transport physics underlying these limitations, and correlate the experimental and simulated results to real print outcomes. Then, we introduce a new hybrid AM method that helps overcome these restrictions by taking active mechanical control of fluid flow during printing: injection CLIP (iCLIP).

High-resolution Continuous Liquid Interface Printing (CLIP) technology is a promising additive manufacturing technique for delivering high-resolution micro-architectures with phenomenal print quality suitable for a wide range of applications, including bio-oriented applications in drug delivery, op…
Improving plastic circularity has been identified as a pressing need due to the large global volume of plastics, their relatively low recycling rate, and their heterogeneity…
Additive manufacturing presents a rapid and low-cost alternative to standard methods for the fabrication of microfluidic devices. We have previously developed a method referred to as injection continuous liquid interface production (iCLIP), that successfully resolves 50-µm microfluidic channels…
