DIY 3D印刷社区是行业改进和突破的重要来源，这些英雄经常在没有面孔或名字的情况下分享其创新。这些无名制造商之一，经常光顾爱好者论坛和创意共享RC小组网站，他们通过别名Harcoretaon the forum, has developed an incredible 3D printed jet engine out of their home base in Madrid, Spain.
3D打印的波音787喷气发动机不仅看起来像是其前身的精确副本，而且与原始型号相似。更不用说整个项目都是用Prusa i3 3D桌面打印机上的ABS塑料印刷的，证明了航空空间的创造力可能来自我们自己的房屋。Forum用户Harcoreta配备了工作推力反向器，经历了反复试验的过程，以使引擎复制品栩栩如生。
Harcoretabuilt the first prototype last year, an 18-blade electric ducted fan (EDF), which initially functioned well, but the overwhelmed stock motor attached to the EDF eventually overheated, causing Harcoreta to remodel with the help of his RC Group forum peers. The outcome was indeed a success! Deciding to replicate the General Electric GEnx turbofan design, scaled for the Boeing 787 jet plane, this Maker was certainly aiming to keep the high quality of the design at a fraction of the cost.
The newly designed 3D printed replica of a Boeing 787 turbofan is still equipped with the 18 blade set up, but now includes an internal turbine to cool the engine, a thrust reverser, and a more simplified engine pylon too. The numerous parts to this turbofan are beautifully rendered, and it seems as though only the motor was not created through the 3D printing process. Once the design is completed and fully printed, Harcoreta will proceed to test the turbofan by mounting it on the topside of a Bixler RC plane and giving it a test flight.
What this innovation proves is that anyone with access to a 3D printer has the opportunity to replicate and build upon our industrial production from days of the past. The most important factor, aside from self-motivation, is having a strong community like RC Groups to bounce ideas around with. After taking advice from forum members to make the first prototype even better, Harcoreta is still seeking feedback for the next go around. Projects like this remind us of why 3D printing is such a unique and accessible method to create almost anything, and thanks to one RC Group user from Spain, we will hopefully be able to watch the additive manufacturing industry soar higher and higher up into the sky of 3D innovation.
