  • Semi-robot? 3D printer prints electronic components directly on the skin

In recent advances in 3D printing, researchers at the University of Minnesota have used portable 3D printers designed and developed by them to print electronic copies directly to human hands at a cost of less than $400 (approximately $2,500, or about the price of a cell phone).

"In the future, we envision a soldier who can carry this printer with him, print temporary sensors on his body to detect chemical or biological agents, or solar cells to charge basic electronic devices when needed."

"It's like a black technology, a "variety of Swiss army knives." Everything they need is just a portable 3D printing tool," said the research director Michael McAlpine, professor of mechanical engineering.
