Researchers continue to experiment with materials and extrusion techniques, introducing the use of chaotic flows for improved microarchitectures in the recent study, ‘‘ Using chaotic advection for facile high-throughput fabrication of ordered multilayer micro- and nanostructures: continuous chaotic printing .’

 .

The authors present a unique form of fabrication with a method that allows for more precise control of the structure and surface area being printed through the use of what they call ‘continuous chaotic printing.’ The process relies on a combination of chaos theory and fluid dynamics, in which the flow of material develops into complex fractals. To achieve this, the team created chaotic material flows by reorienting and splitting fluid as it is mixed, as shown in the figure below. With a focus on multiple materials, multiple layers, and fabrication of varying cells in proximity to each other on larger surfaces, their goal was to test the potential […]
