University of California – Berkeley researchers invented new 3D printer, called Replicator, that uses light to solidify liquid into objects instead of layer-by-layer with existing techniques

  • Novel 3D Printer – University of California – Berkeley researchers developed 3D printer called Replicator that uses light to convert liquid into solid objects in minutes instead of forming them layer-by-layer with standard 3D printers
  • How It Works – Projector displays images into revolving vial of 3D printing liquid resin, where photosensitive molecules in liquid reacts with light to deplete oxygen and form solid objects
  • Benefits – Can create smoother, more flexible, and more complex objects than traditional 3D printers, while generating no material waste as uncured material is 100% reusable
  • Initial Applications – Produced statue and customized jawbone model, with 3D printer able to print objects up to four inches in diameter
  • Future Uses – Can revolutionize how products, from prosthetics to eyeglass lenses, are designed and manufactured as 3D printer can add customizable geometry to metallic components
