3D printing has made low-volume manufacturing of highly personalized products both affordable and accessible, but first you need a printer. A number of businesses have sprung up to bridge that gap -- investing in printers so you don't have to -- and now Amazon has opened up a dedicated storefront on its US site to connect customers with these sellers. The themed portal is stocked with over 200 products at launch, from jewelry to homeware to toys, that companies will print to order. Many can be also be customized, whether that simply be choosing a different color or tweaking numerous features of a design. You can also preview a 3D mockup of your creation before you buy, and now if you'll excuse us, we've got bobbleheads to order.
