Personal fabrication

Researchers at Bath University have demonstrated a self replicating 3D printer capable of fabricating various plastic objects. In the future we will see more of these in domestic settings where individuals will be able to produce articles as needed after designing them on the PC.  This particular invention works by effectively spraying molten layers of plastic which then solidify.   

A number of different approaches will be tried and found for this sort of personal fabrication in the future.  Together with 3D displays using holographic techniques and easier to use design software, people will become much more used to working in three dimensions using personal computers and other devices.
