Scientists print 3D structures composed of liquids
A project developed by scientists from the Berkeley Lab's energy department has allowed the creation of 3D impressions made up of liquids by injecting water into silicone oil. The researchers "sculpted" water tubes between 10 micrometers and 1 millimeter in diameter, into another liquid, with different spiral shapes and several meters of compliance. The experiment aims to build electrically conductive, more flexible and malleable materials.Through this technique scientists hope to chemically change these liquid tubes and drive molecules through their channels looking for new ways to separate them. According to the report, the laboratory is producing a new class of materials capable of reconfiguring and repeatedly changing their shape, having the ability to be adapted to different uses, from chemical synthesis, ion transport, etc.

In their experience, after the water was injected into the oil, several oil filaments attached themselves to the individual nanoparticles of the water, forming what they call a kind of glazed "super-soap", such as glass. This material allows to stabilize an interface between the oil and the water, locking the liquid structures in the desired position.The ultimate goal is to achieve an automated process by modifying the components of 3D printers designed to print plastic, replacing them with a syringe and needle that emit liquids. The printer had to be programmed to insert the printer into the oil substrate and inject the default pattern.
