Not to be outdone by eBay, Amazon today opens the doors to a new 3D Printing Store that allows the customization of more than 200 unique print on-demand products. Personalized dog tags, credit card holders, iPhone cases, and even custom bobbleheads are among the first selection of items that Amazon has on offer. The massive online retailer wont be involved in the manufacturing process and is simply connecting its shoppers with established 3D-printing businesses like Sculpteo, Mixee Labs, and 3DLT, who will be responsible for fulfilling orders placed through the new store. The online customer shopping experience will be redefined through 3D printing, says Sculpteo CEO Clément Moreau, as a customers wants are no longer limited to what is in stock but instead by what they can imagine. Moreau thinks Amazons participation will expand the market for 3D-printed goods dramatically and reduce promotional costs for producers.
