3D printing is a mainstream consumer product (2015)

Until recently, this technology was extremely expensive - upwards of $15,000 per machine - and limited to use in industrial prototyping, product design, medical modeling and architectural models.* However, plummeting costs are now making it affordable to consumers.**
Rather than using ink on paper, these machines can actually "print" 3D objects. This is achieved by melting nylon powder and then shaping it based on computer instructions.
Countless different items can be produced – from jewellery and decorative giftware, to children's toys, kitchenware, replacement plugs, hooks, pipes, fittings, flooring and other household essentials.
Users can download new items and configurations from the Web.* Artists and hobbyists can even create their own, using these printers in combination with 3D scanners and modeling software.
In addition to falling costs, another reason that home 3D printing has taken off rapidly is that there is very little manufacturing being done in America and various other countries anymore. As a result, there is little or no pressure by manufacturing special interests against it.
In the decades ahead, this technology will evolve into nanofabricators, capable of reproducing items with atomic precision within minutes. It will ultimately lead to matter replicators with near-instantaneous production of virtually any object – including foodstuffs.
