Most Americans think of manufacturing as something that happens very far away. They believe that it has nothing to do with them, they are simply the consumer of the end product. Three-dimensional (3D) printing is drastically different from all current models of production and it is starting to blur the line between consumers and producers (Finocchiaro). This new technology allows physical products to be printed as easily as words can be printed on a piece of paper and is rapidly becoming more prevalent in consumers ' homes (Brean). 3D printing uses an additive manufacturing process, in which products are constructed layer by layer, with a series of cross sectional slices. The models for these products are created using 3D Computer Aided Design (CAD) software that are then measured for thousands of cross sections to determine how each layer will be constructed. Simple objects, such as a gear, and more complex products with free moving parts that don 't event require assembly can all be developed. This allows for much more efficient customization of products, the creation of shapes that are not manufacturable through traditional methods, a reduction of waste, and the sharing of designs among designers and users. However, 3D printing has significant risks for the security of intellectual property and illegal weapons manufacturing (Berman).

3D technology has the ability to lower the entry barriers in manufacturing and create a new era of customization and creativity…
