3D Printing: The Future is Now
From artistic object to prosthetic arms and legs, 3D printing is being used in amazing and innovative ways. While many of us only now are discovering this new compact personal replicator, designers and engineers are already using huge and very expensive 3D printers for almost three decades, building rapid prototypes of various parts for automotive, defense and aerospace companies. Different printers work with different materials as well as different holding processes. The base material is usually a ceramic, nylon and metal. Prices for the home machine have drop close to $500, making 3D printing obtainable to hobbyists. To know more about the history of 3-D printing and how it works, see the visual below.
