3D printing revolutionalizes manufacturing
 Although it was prototyped in 1984, 3D printing is considered up and coming because the cost of manufacturing them has gone down within the last decade. 3D printers vary in complexity depending on the model. The first step is always laying out a digital model through computer-aided design or modeling software. The raw material the printer uses needs to be as malleable as possible and is mostly in liquid form. Material incudes, but is not limited to rubber, metals, paper, and plastic. Instead of putting all the material in a mold at once, the printers make objects layer by layer, which get fused together. This makes customization simpler than normal machinery. As of now, there are companies, such as Shapeways and 3ders that have 3D printers that consumers can go to in order to have their design made. These companies have a wide variety of ready-made designs their customers can choose from and customize. The actual printing process can take as little as an hour or up to a couple of days. One of its most important features is that fact that just because a design is more complex does not mean it will be more expensive to make. The only cost that needs to be taken into consideration is the materials. So, a complicated figurine will be less than a simple cube that is equal in dimension.
