Amazon is now getting into the 3D printing business!
They current only offer a limited selected of printers, supplies, and printed goods.
I’m not sure what market they’re targeting yet, because typically, it’s not the goods themselves that makes 3D printing cool (it’s the process of manufacturing something super custom). There’s also no option for custom printing (yet).
However, this does provide a marketplace, which will compete with services like Shapeways, who also provides a community marketplace for 3D printed goods.
