One of the main problems with 3D printing over traditional manufacturing methods is that it usually takes a lot more time. This has all changed according to 3D Systems who today announced that a major 3D printing speed barrier has been broken. According to the company they were able to 3D print 2,400 tiny lamp shades in just 20 hours. This equates to 30 seconds per part. The full story on this achievement can be found here: http://3dprint.com/5723/3d-printing-speed-barrier/

This is likely the technology that 3D Systems plans to use in the manufacturing of 'millions or billions' of Google Project Ara modules in the upcoming year. Opinions? Is this a major breakthrough? How important is it?
