3D printing just hit another benchmark, with the recent announcement by Aurora Flight Sciences and Stratasys Ltd that they have developed a 3D-printed, jet-powered unmanned aerial vehicle (UAV) with the ability to reach speeds of up to 150 mph (241 km/h). Unveiled at this week’s Dubai Airshow, it is reportedly the largest and most complex UAV ever created using 3D printing.

3D打印正好碰到另一個標杆，隨著近期宣布極光飛行科學與Stratasys公司公司thatthey已經開發出了3D打印，噴氣式動力的無人機（UAV）一起時速可達150英里每小時的能力（241公里/小時）。亮相本週的迪拜航展上，這據說是使用3D打印的最大，最複雜有史以來無人機。
The high-speed aircraft, designed by Aurora and manufactured and assembled by Stratasys, has a wingspan of 9 feet (3 m) and weighs only 33 lb (15 kg). Over 80 percent of it was created using a 3D-printing process called Fused Deposition Modeling (FDM) that allows for the production of large yet lightweight objects.
The fuselage itself was made of nylon, while the engine exhaust duct was 3D-printed in metal to withstand the high heat generated in that area of the aircraft.
高速飛機，極光設計和製造，並通過Stratasys公司組裝的，有9英尺（3米）的翼展，重量只有33磅（15千克）。超過80它創造了什麼使用稱為熔融沉積成型（FDM），三維印刷工藝，使生產大而輕便的對象的百分比。
機身本身是由尼龍製成的，而其中的3D印刷在金屬發動機排氣管道能夠承受在飛機的這一區域產生的高熱量。
Both companies said the main goal of the project was to illustrate that it was possible to quickly go from designing to manufacturing to flying a lightweight, jet-powered aircraft. The longest print time was for the center-body fuselage, which Stratasys said took about nine days to create. All of the rest of the components – wings, nozzle, fuel tank and other small parts – were manufactured concurrently and took anywhere from a few days to a few hours to complete.
A little more than a month was spent on the initial integration, assembly and testing.
Stratasys said that with all of the integration elements now worked out, it could build a second one in two to three weeks from start to finish.
兩家公司表示，該項目的主要目標，說明它做了什麼可以快速從設計到製造到懸掛重量輕，噴氣動力的飛機去。最長printTime什麼Hanes的中心體機身，這Stratasys公司說大約過了九天創建。所有組件的其餘部分 - 機翼，噴嘴，燃油箱等小部件 - 被製造同時並採取任何地方從幾天到幾個小時才能完成。
不到一個月的初始集成，組裝和測試花費多一點。
Stratasys公司說，所有的積分元的現在制定出來的(所有整體的元件都整合完成)，它可以建立一個第二次是在兩到三週內從開始到結束。
This is not the first UAV to be created via 3D printing. In April 2014, University of Sheffield's Advanced Manufacturing Research Center (AMRC) made a 3D-printed UAV airframe that could be printed and in the air within a single day. Later in October of the same year, they added electric motors that could propel the craft at speeds of up to 45 mph. Stratasys and a team from Boeing were involved in that project.

這不是要通過三維打印創建的第一個UAV。在2014年4月，謝菲爾德先進製造研究中心大學（AMRC）製成，可能是一天內打印並在空氣中的3D打印無人機機身。後來在同年10月，他們增加了電動馬達推動，可以在高達45英里每小時。Stratasys公司的速度和波音團隊參與了其實項目的工藝。
