DW Documentary ---------------------------------- Three-dimensional printing promises new opportunities for more sustainable and local production. But does 3D printing make everything better? This film shows how innovation can change the world of goods. Is the way we make things about to become the next revolution? Traditional manufacturing techniques like milling, casting and gluing could soon be replaced by 3D printing -saving enormous amounts of material and energy. Aircraft maker Airbus is already benefiting from the new manufacturing method. Beginning this year, the A350 airliner will fly with printed door locking shafts. Where previously ten parts had to be installed, today thats down to just one. It saves a lot of manufacturing steps. And 3D printing can imitate nature's efficient construction processes, something barely possible in conventional manufacturing. Another benefit of the new technology is that components can become significantly lighter and more robust, and mat
