Thought this would be cool got it in a email , Just think of all those parts that could be made from this,
machines that are rare or hard to find parts.

3D Printer !!!
This printer is used in "parts, assemblies, tools, packaging & containers" designs, for example plastic water bottles, before they actually manufacture the bottles. The designers have almost unlimited possibilities to design a 3D model of practically any object, print a 3D prototype to test in real life applications before the object is manufactured!
