New perspective "Growing three-dimensional objects with light" overviews current state of vat photopolymerization
Congratulations to mechanical engineering PhD candidate, Gabriel Lipkowitz, and chemical engineering postdoc, Max A. Saccone, on their recent publication of their PNAS perspective paper! Their paper, titled ‘Growing three-dimensional objects with light’, overviews the recent advances, capabilities, and exciting new horizons for the additive manufacturing category of vat photopolymerization (VP). As part of this perspective, they enlist the help of Matthew Panzer from Carbon, Inc. to visualize the fascinating effect that an oxygen-rich dead zone in continuous liquid interface production (CLIP) VP has on enabling high speed, continuous VP 3D printing. The VP technologies outlined in their paper are revolutionizing scalable production of non-moldable high resolution advanced structures used throughout the DeSimone lab's research projects. Other Stanford co-authors and DeSimone Lab members on this paper include Ian A. Coates, Kaiwen Hsiao, Daniel Ilyin, Jason M. Kronenfeld, John R. Tumbleston, Eric S. G. Shaqfeh, and Prof. Joseph M. DeSimone.
High resolution roll-to-roll 3D printing enables daily production of 1 million microscale particles
Congratulations to chemistry PhD candidate, Jason Kronenfeld, on the recent publication of his Nature paper on Pi Day 2024! His paper, titled ‘Roll-to-roll, high-resolution 3D printing of shape-specific particles’, demonstrates the use of roll-to-roll continuous liquid interface production (r2rCLIP) with single-digit, micron-resolution optics. This technique addresses previous particle fabrication shortcomings, enabling the rapidly permutable fabrication and harvesting of shape-specific particles from a variety of materials and with complex geometries. This enables production of micron-scale shapes, ranging from moldable to non-moldable, at speeds of up to 1,000,000 particles per day. This “digital dust” enables direct integration within biomedical, analytical, and advanced materials applications, ranging from hard (ceramics) to soft (hydrogels). Other Stanford co-authors and DeSimone Lab members on this paper include Lukas Rother, Max A. Saccone, Maria T. Dulay, and Prof. Joseph M. DeSimone.
