Foreign scientists have just recently developed a new method, through 3 d printing technology to produce 3 d structure of completely composed of liquid, for those who need flexible scalable device of electronic equipment manufacturing has paved the way.
The department of energy's Lawrence Berkeley national laboratory, the researchers used a modified type of 3 d printers, through the water injection silicone oil, and then another kind of liquid in a liquid pipe of 3 d printing sculpture.
According to scientists predicted that molecules through chemical method and the pipe flow adjustment, so as to find a new method to separate molecules or accurately will be transported to the underlying building materials at the nanoscale.
Researchers have printed "waterlines" between 10 and 1 millimetres in diameter and formed a length of several metres in different spiral shapes and branches.
According to the results published in advanced materials, the material can adapt to the surrounding environment and constantly change its shape.
"This is a new type of material, can reconfigure itself, have be customized for the potential of liquid reaction vessel, and there are many application prospect, catalytic from chemical synthesis, ion transport."
Tom Russell, a scientist at the Berkeley lab.
The origins of this material are attributed to two aspects: learning how to create a liquid tube to form a shape in another liquid, and then automating the process.
In the first step, the scientists developed a way to fix water in a special nanoparticle surfactant to hold water in place.
Surfactant, essentially soap, prevents the tube from breaking down into liquid.
Their surfactants can be very effective, and scientists call them nanoscale super soaps.
This is achieved by dispersing nanoparticles into water and polymers and distributing them into oil.
Nanoparticles and polymer ligands want to connect to each other, but they also want to stay in their own water and oil media.

In the experiment, dozens of ligand in the oil were attached to individual nanoparticles in the water shortly after the water was injected, forming a nano-scale super soap.
These super soaps can be squeezed together like glass, making the interface between oil and water very stable and locking the liquid structure.
"This stability means that we can stretch water into tubes, and it's still a tube.
Or we can make the water an ellipsoid, and it's still an ellipsoid.
"We use these nanoscale super soaps to print a lot of water pipes."
The researchers then modified an existing 3D printer to remove the parts that were designed to print plastic and squeeze the liquid out with a syringe pump and a needle.
They then asked the printer to insert the needle into the oil base and inject water into the intended model.
"We can squeeze the liquid out of the tube and place it anywhere we want in three dimensions."
"Said Joe Forth, a postdoctoral researcher.
"We can also use external forces to flatten the material so that the stability of super soaps can be broken in an instant, and the shape of the waterline is changed. This structure has a high bearing capacity."
