The components for the blades were tested at 13,000 rpm and temperatures in excess of 1,250 C (2282 F)at the company’s industrial gas turbine factory in Lincoln, UK. .

The 3D-printed blades, featuring a completely revised and improved internal cooling geometry, were produced from a high-temperature-resistant, powdered polycrystalline nickel-based superalloy and installed in a Siemens SGT-400 industrial gas turbine with a 13 MW capacity. At full load each of these turbine blades travels at over 1,600 km/h and carries 11 tons (see video).

With additive manufacturing technology, the engineers reduced the period of time from the design of a new gas turbine blade to its production from two years to two months.
