Three Dimensional printers or 3-D printers, are just like the printers we all know and love, except instead of printing an image of a thing, it prints the thing itself. That, and they may look a tad different from your desk jet. 3-D printers can print products almost without regard to geometrical limitations, through subtraction and or fusing methodologies, providing a designer or inventor incredible flexibility, freedom, and speed in sketching an item having said item in hand. Excitingly, while 3-D printers have been around for quite a while, they have become increasingly affordable, efficient, and accurate.
