Intech DMLS, a metal additive manufacturing company from India, have announced the development of the country’s first jet engine series.
Developed by Intech’s R&D arm, ‘Poeir Jets’, the MJE20 engine starts small, powering unmanned aerial vehicles (UAVs) and remote-controlled aircraft.According to the Times of India，这将使他们成为第一个开发土著喷气发动机的亚洲国家。
A forward-looking statement from Sridhar Balaram, director of Intech, suggests this won’t be the last jet engine created in the country either. They are already developing future engines which will serve larger planes:
…我们看到的成功促使我们开发了更大的引擎。我们拥有MJE-40和MJE-100，它将能够为更大的无人机提供动力。

The current engine, weighing just over 2 kg, can provide an uninstalled thrust of 20 kg, and as such is not designed to power larger aircrafts. Balaram says“正是由于这个原因，我们将在24个月内准备好获得认证。”添加“鉴于它们是燃气轮机发动机，他们将提供更长的飞行时间。”
领先的直接金属激光烧结（DMLS）技术以“ Sintenering Innovations”为名，与钛，inconel，Inconel，Cobalt Chromium，不锈钢菌株，铝和Maraging Steel钢粉一起工作，以与钛一起工作，以生产零件。他们的服务涵盖航空航天，汽车，工具和模具，快速原型和医疗行业的项目。
Balaram’s latest update on the MJE20’s development is as follows:
We fired the engine for the first time on February 8, 2017, and it was a success. Some other tests are going on, and we are confident that it will be ready to be presented for certification in 18-24 weeks.
Global trends in metal additive manufacturing
雷电竞充值正如GE将技术纳入其新发动机中，增材制造业在航空业中证明了其价值。GE9X飞机发动机有已经对其3D打印组件进行了首次测试。而通用电气也有他们的3D printed LEAP engine nozzle certified for use。
德国科技集团西门子还使用添加剂制造来生产雷电竞充值燃烧引擎的刀片。该技术特别适合于发动机承受高应力并需要有效替换之类的生产。雷电竞充值这些零件的增材制造大大减少了时间成本。就西门子的涡轮刀片而言，从设计到测试仅需18个月的生产，比传统方法快约90％。
金属添加剂制雷电竞充值造开发项目可以在第一届年度3D印刷行业奖中提名。
