New 3D nanoprinting strategy opens door to revolution in medicine, robotics

Engineers have created the first 3D-printed fluid circuit element so tiny that 10 could rest on the width of a human hair. The diode ensures fluids move in only a single direction -- a critical feature for products like implantable devices that release therapies directly into the body.
