The laser-assisted direct ink writing method prints microscopic metallic, free-standing 3-D structures in one step, without auxiliary support material. Lewis’ team used an ink composed of silver nanoparticles. The ink is sent through a printing nozzle and then annealed using a precisely programmed laser that applies just the right amount of energy to drive its solidification. The printing nozzle moves along x, y, and z axes and is combined with a rotary print stage to enable freeform curvature.
