printing is when you add successive layers of material are laid down under computer control.These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
The most common material used in the printer is plastic, however you can use other materials such as:
metal alloys;
plaster;
metal foil;
ceramics.
They are also working on nanoscale 3D Printing, allowing you to print very small items. Using a sort of metal-vapour.
