Siemens

Building prototypes for machinery takes a lot of time and creates a lot of waste. Additive manufacturing, a.k.a. 3D printing, reduces both, and Siemens, which makes everything from locomotives to medical X-ray machines, has embraced it avidly. Siemens says additive techniques have enabled its gas- and steam-turbine unit to reduce development time by 75% and use an average of 65% fewer resources in the production process. The company also makes and sells software that helps customers reap similar 3D rewards.
