The online retail giant stepped deeply into the world of 3D printing by launching a new “Main Product Category” called “3D Designs & Print on Demand”. It’s very much like Shapeways or Sculpteo: great designs may be browsed, searched, selected, printed and then shipped to your door. At present the service boasts over 200 products, some of which are customizable. Shapeways has teamed with Mixee labs to provide twenty 3D model generators with which customers can quickly design personalized objects of various kinds. Generators include various rings, pendants, figurines and items of jewelry. They’re easy to use and prices are reasonable, at least for 3D printing.
