Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering and the John A. Paulson School of Engineering and Applied Sciences (SEAS) developed a new 3D printing method.
They use a miniature nozzle to spray silver ink that is solidified by lasers in midair to produce self-supporting 3D structures.
The application of this technology will probably be in advanced electronics circuits production or biomedical devices.
Here is the video of the process:
