IT'S IMPOSSIBLE TO OVERSTATE DEFLATIONARY PRESSURES:

Not so long ago, the prevailing thinking in industry was that the lowest-cost manufacturing was large, mass manufacturing in low-labor-cost countries like China. At the time, in the early 2000s, only Fortune 500 companies and major research universities had access to 3D printers. The machines were massive, expensive tools used to rapidly prototype parts and products.

More than a decade ago, the patents expired on the first type of 3D printing, and a professor in Britain had the intriguing idea of making a 3D printer that could print itself. He started the RepRap project - short for self-replicating rapid prototyper - and released the designs with open-source licenses on the web. The designs spread like wildfire and were quickly hacked and improved upon by thousands of engineers and hobbyists all over the world.

Many of these makers started their own companies to produce variants of these 3D printers, and people can now buy a 3D printer for US$250 to $550. Today's 3D printers are full-fledged additive manufacturing robots, which build products one layer at a time. Additive manufacturing is infiltrating many industries.
