Researchers from the University of Minnesota have recently developed a way to place electronics directly onto a person's skin by using a custom-made concept portable 3D printer. Developed with soldiers in mind, the portable 3D printer is being pushed as an incredible tool for soldiers on the field. The ability to print almost anything while out in the field can prove immensely useful and the ability to print directly onto the skin can ensure that sensors can be constructed and applied immediately.
Early demonstrations of the portable 3D printer have shown the printer's ability to work on a moving hand and how the entire process works. By placing tracking markers on the hand, each acts like a map and guides the 3D printers that adds layers of conductive ink with silver flakes that cure at room temperature. The concept portable 3D printer can also do more than print technological items as it also works for medical needs and can successfully print biological cells onto wounds.
