“Engineers at the European Aeronautic Defence and Space Company (EADS) have used this technique to print out an entire bicycle that only needs added tires and a chain to be fully functional. British researchers, meanwhile, have printed a maneuverable drone with a rear-engine drive. Printed components are also used in Formula 1 racing and at NASA. Dental laboratories use 3-D printers to produce crowns, while doctors experiment with artificial heart tissue. Filmmakers also print animation models and automotive parts suppliers create replacement parts. The printing of electronic components is even in the works.”
