Structures that are periodic on a microscale in three dimensions are abundant in nature, for example, in the cellular arrays that make up living tissue. Such structures can also be engineered, appearing in smart materials1–4, photonic crystals5, chemical reactors6, and medical7 and biomimetic8 technologies. Here we report that fluid–fluid interfacial energy drives three-dimensional (3D) structure emergence in a micropillar scaffold. This finding offers a rapid and scalable way of transforming a…

Additive manufacturing of high aspect-ratio structures with self-focusing photopolymerization

1 Photocrosslinkable polymers have been exploited to attain impressive advantages in printing freestanding, micrometer-scale, 2 mechanically compliant features. However, more integrated understanding

Asymmetric invasion in anisotropic porous media.

It is argued that the invasion process occurs as long as the pressure drop is larger then the macroscopic capillary pressure determined by the front roughness, which in the case of flow-opposing pillars is halved, allowing for fabrication of porous capillary valves to control the flow along certain specific directions.

Endless forms fabricated

The patterning dynamics of confined immiscible fluids has inspired an elegant and versatile approach to building periodic three-dimensional multi-material architectures. The technique extends to



A Tissue-Like Printed Material

Printed droplet networks might be interfaced with tissues, used as tissue engineering substrates, or developed as mimics of living tissue, as well as functionalized with membrane proteins and programmed to fold.

Self-generation of two-dimensional droplet array using oil-water immiscibility and replacement.

Designable 3D Microshapes Fabricated at the Intersection of Structured Flow and Optical Fields.

Using this approach, high-resolution production of complex microshapes not producible using alternative methods is demonstrated, such as octahedrons, dreidels, and axially asymmetric fibers, at throughputs as high as 825 structures/minute.

Fluid breakup during simultaneous two-phase flow through a three-dimensional porous medium

We use confocal microscopy to directly visualize the simultaneous flow of both a wetting and a non-wetting fluid through a model three-dimensional (3D) porous medium. We find that, for small flow

Fabrication of fillable microparticles and other complex 3D microstructures

A microfabrication method is described, termed StampEd Assembly of polymer Layers (SEAL), and injectable pulsatile drug-delivery microparticles, pH sensors, and 3D microfluidic devices that the authors could not produce using traditional 3D printing are created.

Entropic lattice Boltzmann method for multiphase flows: Fluid-solid interfaces.

Simulations of drop impact onto both wettable and nonwettable surfaces show that the ELBM reproduces the experimentally observed drop behavior in a quantitative manner, and is a promising alternative for studying the vapor-liquid-solid interface dynamics.
