My dream is to develop and invent a 3D printer that can shape and manufacture die cast car models so I can sell it. On the other hand, the device will be developed to shape metal objects to benefit people and other industries.
In the medical field 3D metal printers would create tools easily and instantly to heal patients like: heart pace makers. Electronics part manufacturers could send the tools through the printer at the time of order to the printer and the customer will get his part in no time. Other industries will also depend on this printer.
New inventions help change how we do our daily operations and the way we get our needs. As long as the inventions are easy to use and developed successfully it will change the world
