There’s so far no name for the new tech, but it’s basically a nozzle that moves along a preset path and sends out a thin stream of silver nanoparticles. A laser simultaneously follows its progress, heating the particles and solidifying them into a freestanding filament. “I am truly excited by this latest advance from our lab, which allows one to 3D print and anneal flexible metal electrodes and complex architectures ‘on-the-fly,’ ” said lead researcher Jennifer Lewis in a news release. “This sophisticated use of laser technology to enhance 3D printing capabilities not only inspires new kinds of products, it moves the frontier of solid free-form fabrication into an exciting new realm.”
…Whatever that means. A little confused? Check out the video below that’ll blow your mind a little more.
*anneal (verb): heat (metal or glass) and allow it to cool slowly, in order to remove internal stresses and toughen it.
