3D Printers
Background Information: We're all familiar with the idea of printing on a two-dimensional scale, but three dimensional printing is a fairly new advancement in the manufacturing and engineering industries. The first instance of 3D printing was in 1980 when Dr. Kodama used it as a rapid prototyping technique. Since then, 3D printing technology has taken off and advanced in many ways. 3D printers have been used to produce 3D printed organs from the cells of a patient, they have been used in the automotive and aerospace industries, and to create prosthetics. How it Works: Most 3D printers use plastic or metal that is melted down or in powder form to create layers of an object until it is complete. The printers are controlled by a computer that directs the arm and head in the X, Y, and Z directions. The melted plastic or metal is placed in specific spots on the base by the arm, as programmed on the computer, creating the first layer of an object. Once the first layer is co
