Rather than building objects layer by layer, the printer creates whole structures by projecting light into a resin that solidifies.
The research, published in the journal Science yesterday, describes a printer the researchers nicknamed “the replicator” in a nod to “Star Trek.”
It works more like a computed tomography (CT) scan than a conventional 3D printer. It builds a 3D image by scanning an object from multiple angles, then projects it into a tube of synthetic resin that solidifies when exposed to certain intensities of light. In two minutes, for instance, the team was able to fabricate a tiny figurine of Auguste Rodin’s famous “The Thinker” statue. Sources : (futurism.com – nature.com)
