Amazon has set up a new division selling 3-D printed products in partnership with five companies. The Cincinnati Business Courier broke the news yesterday about what it calls a new pilot program to sell 3-D-printed products in four categories: toys, home accessories and decor items, jewelry and fashion/tech accessories. Amazon has sold 3D printers and supplies for some time, and third-party merchants are already listing 3D printed objects on Amazon independently, as they do on other marketplaces including Etsy.
