The sleek race car dubbed 'Blade' didn't come off an assembly line - but out of a 3D printer. Kevin Czinger of Divergent Microfactories has spent most of his career in the automotive industry. One day he realized that no matter how fuel-efficient or how few tailpipe emissions the modern car has, the business of car manufacturing is destroying the environment. "3D printing of metal radically changes that," said Czinger. Currently cars are pieced together on long assembly lines inside large factories that use massive amounts of energy. Even the most fuel-efficient car has a large carbon footprint before ever leaving the plant. Czinger and his team's approach was to take the large plant out of the equation. To accomplish this they printed the modular pieces that are used to connect carbon rods that make up the Blade's chassis. The 3D printed chassis is only 102 pounds and has the same strength and safety protection as a frame made out of steel. By using carbon fiber instead of steel or aluminum for the body, the entire vehicle only weighs 1400 pounds (635kg). The Blade ... runs on natural gas, reducing its carbon footprint even further. The core enabling technology, the ability to print out car components that can be easily assembled, is what Kevin Czinger hopes will revolutionize car manufacturing. He says electric cars are a step in the right direction, but alone they won't be enough to curb greenhouse emissions given the projected rise in demand for cars globally unless the way they are manufactured changes.
