Adrian Bowyer envisions a common manufacturing device that could make Wal-Mart practically obsolete. Instead of running out to buy a set of goblets or plates, you'd simply design them on your make-it-all machine and push a button. Poof, whatever you want comes out.
His idea is based on "rapid prototype machines," which industry already uses to make plastic auto parts. A concept is detailed in 3D on a computer, and then the machine manufactures the item automatically.
But if Bowyer can pull it off, the machine would inarguably be a handy addition to any stable of household appliances. While it sounds like a huge "if" for now, Bowyer sees it all coming true in just a few years.
People have been talking for years about the cost of these machines dropping to be about the same as a computer printer," Bowyer, a "biomimetics" researcher at the University of Bath in the UK. "But it hasn't happened. Maybe my idea will allow this to occur."
"If these machines take off, it will give individual people the chance to do this themselves, and we are talking about making a lot of our consumer goods," Bowyer said. "The effect this has on industry and society could be dramatic."
