3D printing has become an important and ever-growing industry,
3D printers are available in a variety of forms and prices, from the
lower priced desktop 3D printers to the industrial giants, with the
ability to handle several materials, not only the classic plastic forming
devices, but extending to other industries such as electronics, homes,
food, cars, medicine and healthcare. Although the concept of 3D printing
dates back to the ‘80s, 
3D printers became popular only during the past
decade; this is in part caused by the expiration of the patent for
Fused Deposition began appearing and some affordable 3D printers hit the market.
