Harvard researchers have designed new printheads for 3-D printers that can simultaneously handle multiple materials with different properties, allowing for 3-D printing wearable devices, flexible electronics, and soft robots.
To print a flexible device, including the electronics, a 3-D printer must be able to seamlessly transition from a flexible material that moves with the wearer’s joints for wearable applications, to a rigid material that accommodates the electronic components. It would also need to be able to embed electrical circuitry using multiple inks of varying conductivity and resistivity, and precisely switching between them while changing composition and geometry. And do it all in real time.
