HP has been testing out a new printer that they have been working on for many years now, a 3D printer. You could literally fill it up with wax and it could make you a candle, or you could fill it up with food and it could make you something out of those food substances.
By 2020, 3D printers are expected to be in every household and as common as cell phones are now a days.
I think this is really cool, but at the same time frightening to think about. Technology is moving so fast and it seems like everything is becoming 3D, every movie is now released in 3D! I`m pretty sure by 2020 they will be testing out 4D!
What do you guys think?
