3D printing is the process of making a physical object from a digital model. It is also known as additive manufacturing because the physical model is built up one layer at a time. Our 3D printer uses a process called Fused Deposition Modeling (FDM), in which a plastic filament is fed through a heated nozzle which melts the plastic. Computer-controlled motors move the nozzle around to create the shape of a layer, which hardens immediately. The object is built this way, one layer at a time, from the bottom up.
