Watch this nanolab print liquid 3D structures

By creating a surfactant that holds water in place, scientists are able to produce repeatable liquid 3D shapes in these nanoparticle "supersoaps" with modded off-the-shelf 3D printers.

Via Berkeley Lab:

Berkeley Lab scientists have developed a way to print 3-D structures composed entirely of liquids. Using a modified 3-D printer, they injected threads of water into silicone oil — sculpting tubes made of one liquid within another liquid.

They envision their all-liquid material could be used to construct liquid electronics that power flexible, stretchable devices. The scientists also foresee chemically tuning the tubes and flowing molecules through them, leading to new ways to separate molecules or precisely deliver nanoscale building blocks to under-construction compounds.
