It's been a few months since I looked at how 3D printing technology is progressing. The price of the MakerBot machine has dropped $200 bringing it down to $999 (still about £800 from the UK site I checked though). I'm sticking with my prediction that by the end of 2012, we'll see a sub $500 consumer 3D printer on the market.
For a good snapshot on the different ways the technology is developing, take a look at the BBC video in the link below. It shows three different types of 3D printers in action.
