3D Printer Uses Liquid Metal | Smart Planet

Leave a comment

One major criticism of 3D printers is that the main material used for printing is plastic. How many items do you have that are made of only plastic? Not many. On a commercial scale, the use of plastic in 3D printers probably won’t change for a while, but researchers are developing some fascinating new materials used as “ink” for 3D printers.

The latest example comes from North Carolina State University where researchers have developed techniques to make free-standing structures using liquid metal at room temperature.

“It’s difficult to create structures out of liquids, because liquids want to bead up. But we’ve found that a liquid metal alloy of gallium and indium reacts to the oxygen in the air at room temperature to form a ’skin’ that allows the liquid metal structures to retain their shapes,” said Dr. Michael Dickey, a professor at NC State University and co-author of a new paper on the process, in a statement.

The researchers plan to use the process to develop electronics applications, especially useful for bendable electronics, as New Scientist reports:

It should be easy to swap the syringe for the nozzle of a 3D printer, potentially letting you print plastic objects containing metal wiring with a single device. “You could include this as a functional ink that you use with a 3D printer,” says Dickey.

The only drawback? The cost of printing with liquid metal is about 100 times more than the plastic used in 3D printers.

Scientists Reveal New Insights On Nano 3D Printing | R&D

A nanostructure fabricated using EBID.Techniques for the manipulation of matter at the nanoscale are a step further ahead with the publication of new results from a University of Technology, Sydney (UTS) research group.

A team of physicists funded by FEI Company and the Australian Research Council have unveiled new physics behind the nanofabrication technique known as electron beam induced deposition (EBID), essentially 3D printing at the molecular level.

The UTS team has reported new insights into the behavior of molecules at surfaces to achieve extraordinary improvements in speed and the quality of materials fabricated using the EBID technique.

Using the UTS FEI laboratory and an advanced research grade electron microscope the scientists have been able to explain the nature of chemical reactions on hot, solid surfaces and to “write” highly pure nanostructures.

The UTS experiments have led to the discovery that the EBID technique performs optimally under conditions previously dismissed as ineffective, due to gaps in prior understanding of the basic science behind EBID.

One of the researchers, Professor Milos Toth says, “Techniques for manipulation of matter at the nanoscale critically underpin the development of future generation electronics, photonics and materials used in renewable energy technologies.”

“Our findings help advance the techniques and build the machines used to advance nanoscale science and technology.”

“These discoveries are enabled by the cutting edge FEI equipment used by research staff and students at UTS,” Toth says.
