    An engine measuring 20 by 30 centimeters and a speed of 33 thousand revolutions per minute has been successfully tested in a division of GE Aviation. It is worth noting that this is the first jet engine sold exclusively using 3D printing technology.



    The engineers took several years to create the model. Most of the time it took to debug additive printing technology and configure the hardware. For this, the engineers at the Additive Development Center used a special printer with a powerful laser that melts metal powder in a strictly specified order.

    The 3D printing process itself takes no longer than in the case of traditional plastic. Therefore, over the next month, GA plans to use this technology to begin mass production of fuel injectors for its new LEAP jet engine line.

    By the way, Airbus is also actively using 3D printing technology, which uses more than 1000 parts printed on a 3D printer in its new A350.

    PS More about industrial, steel and chocolate 3D-printing will be available at a specialized conference in St. Petersburg.
