SiemensBreakthrough in 3D printing
Siemens continues to make progress in 3D printing: The company announces the first successful test for additively manufactured gas turbine blades under full load.

In the 3D printing process used by Siemens, the fiber laser shapes the turbine blades using a digital production plan, also known as a CAD model. A laser beam moves over a layer of metal powder and welds the first layer of the three-dimensional object. A new layer of metal powder is then spread over the surface. Now the laser beam prints a second layer. Step by step, the turbine blade is created.
