3d printers are not news. They are pretty damn cool though.

It's true that 3D printers are not new, however cheap (compared to commercial/industrial) and accessible personal 3D printers that produce quite a few of their own parts are rather new.
Granted the first RepRap design was made in 2007 (and the similar Fab@Home Project started in 2006), however these auspicious devices haven't exactly been in the limelight which is why I thought I'd mention them now.
