In a Sense, 3D Printing as you Know it, is a Lie -- it's Really Stacking a Series of 2D Layers on Top of Each Other, rather than Forming a Single Object. That's Where Carbon3D Might Come to the Rescue. It just Unveiled a 3D Printing Technique, Continuous Liquid Interface Production, that Creates True, Contiguous 3D Items by Blasting a Resin Pool with Bursts of Light (which Hardens the Resin) and Oxygen (which Keeps it in a Liquid State). As the Washington Post Notes, the Approach Both Looks like and was Inspired by the Shapeshifting 'T-1000' Robot in Terminator 2 -- Solid Objects Emerge Out of an Amorphous Goo. The Unusual Method Isn't just for Show, of course.
Since you Don't Need to Craft Items Layer-by-Layer or Worry about Eliminating Seams, you Can Print Objects 25 to 100 Times Faster than Usual; that Figurine you Want, Could be Ready in Minutes, Not Hours. Also, the Smoother, Stronger Output is Much Better Suited to Real-World Uses, such as Irritation-Free Medical Implants. There's No Mention of When Carbon3D's Technology will Land in Something you Can Buy but, the Potential Impact is Huge. You Could Craft 3D-Printed Goods at Home that, are Much Closer to Commercial Quality and you Wouldn't Even Have to Wait Long to Hold the Finished Product in your Hands.
