Four-dimensional micro-building blocks: Printable, time-related, programmable tools

Four-dimensional (4-D) printing is based on merging multimaterial printing, reinforcement patterns or micro and nanofibrous additives as time-related programmable tools, to achieve desired shape reconfigurations. However, the existing programming approaches still follow an origami design principle to generate reconfigurable structures using self-folding and stacked 2-D materials at small scales. In a new report on Science Advances, T. Y. Huang and a team of interdisciplinary, international researchers in the U.S. and China proposed a programmable modular design to directly construct 3-D reconfigurable microstructures capable of 3-D-to-3-D transformations via 4-D micro-building block assembly.
