Printing in the 21st Century

Speaking of self-replication...

"A self-replicating 3D printer that spawns new, improved versions of
itself is in development at the University of Bath in the UK. The 'self
replicating rapid prototyper' or RepRap could vastly reduce the cost of
3Dprinters, paving the way for a future where broken objects and spare
parts are simply 're-printed' at home. New and unique objects could also
be created. 3D printing - also known as 'rapid prototyping' - transforms a
blueprint on a computer into a real object by building up a succession
of layers. The material is bonded by either fusing it with a laser or by
using alternating layers of glue.”

Sounds like science fiction doesn’t it? Then again, we are in the 21st
Century folks!
