3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.

The machines are getting cheaper, and soon may be desktop items. Making your own common objects at will will be an interesting thing....

The technology, and the computers are new, but, the concept of making something three domentional out of something two dimentional, is in fact, very very very old.....

They got the hanging ring wrong.   The teeth and gear are not correct...  That means the program has some preconceived ideas planted in it.
But seriously, what amazing stuff! 

Wonder what it costs...  Could we afford a Stanley No. 1 for each of us?
