• Injection continuous liquid interface production of 3D objects

  Science Advances · 2022 · 142 citations

  In additive manufacturing, it is imperative to increase print speeds, use higher-viscosity resins, and print with multiple different resins simultaneously. To this end, we introduce a previously unexplored ultraviolet-based photopolymerization three-dimensional printing process. The method exploits a continuous liquid interface-the dead zone-mechanically fed with resin at elevated pressures through microfluidic channels dynamically created and integral to the growing part. Through this mass tran…

• Single-digit-micrometer-resolution continuous liquid interface production

  Science Advances · 2022 · 93 citations

  To date, a compromise between resolution and print speed has rendered most high-resolution additive manufacturing technologies unscalable with limited applications. By combining a reduction lens optics system for single-digit-micrometer resolution, an in-line camera system for contrast-based sharpness optimization, and continuous liquid interface production (CLIP) technology for high scalability, we introduce a single-digit-micrometer-resolution CLIP-based 3D printer that can create millimeter-s…

• Growing three-dimensional objects with light

  Proceedings of the National Academy of Sciences · 2024-07-01 · 26 citations

  articleOpen access

  Vat photopolymerization (VP) additive manufacturing enables fabrication of complex 3D objects by using light to selectively cure a liquid resin. Developed in the 1980s, this technique initially had few practical applications due to limitations in print speed and final part material properties. In the four decades since the inception of VP, the field has matured substantially due to simultaneous advances in light delivery, interface design, and materials chemistry. Today, VP materials are used in…

• Perspectives on viscoelastic flow instabilities and elastic turbulence

  Physical Review Fluids · 2022-08-29 · 13 citations

  preprintOpen access

  Viscoelastic fluids can exhibit striking flow instabilities under conditions where ordinary Newtonian fluids are stable, owing to the nonlinear coupling of the elastic and viscous stresses. This article provides perspectives on viscoelastic flow instabilities by integrating the input from speakers at a recent international workshop: historical remarks, characterization of fluids and flows, discussion of experimental and simulation tools, and modern questions and puzzles that motivate further stu…

• High-resolution stereolithography: Negative spaces enabled by control of fluid mechanics

  Proceedings of the National Academy of Sciences · 2024-09-04 · 12 citations

  articleOpen access

  Stereolithography enables the fabrication of three-dimensional (3D) freeform structures via light-induced polymerization. However, the accumulation of ultraviolet dose within resin trapped in negative spaces, such as microfluidic channels or voids, can result in the unintended closing, referred to as overcuring, of these negative spaces. We report the use of injection continuous liquid interface production to continuously displace resin at risk of overcuring in negative spaces created in previou…
