By using a precise form of additive manufacturing (layering material), as opposed to subtractive (removing material), a new technology called 3D printing prints a complex three-dimensional object from raw materials. These raw materials can range from PVC plastic to titanium metal to bio-ink, and through the precision of inkjet-like printing heads, can be formed into products from large titanium jet engine parts to microscopic kidney cell structures. Three-dimensional printing is the future of manufacturing and, by changing manufacturing techniques, will disrupt many parts of society.
