wow, looks totally insane.

Scientists are pioneering the use of 3D printers to create drugs and other chemicals at the University of Glasgow. Researchers have used a £1,250 system to create a range of organic compounds and inorganic clusters - some of which are used to create cancer treatments.

"Austin, Texas (CNN) -- Four years ago an unknown startup called MakerBot showed up at the South by Southwest Interactive conference here with a prototype of its first desktop 3-D printer, which spit out plastic replicas of small objects. Bre Pettis, the company's co-founder, took the machine around to Austin's watering holes, set it on the bar and showed off its capabilities by printing shot glasses.

On Friday, Pettis was back at SXSW, this time as a keynote speaker before a packed hall of 3,000 people, further evidence that 3-D printing is a hot trend in the tech world. Once again, he brought a new prototype with him."
