Launcher， 一个American private aerospace company, has scheduled the first full-scale test of itsE-2rocket engine采用3D印刷燃烧室。该日期为2020年代中期，并计划在公司获得150万美元的奖励后U.S. Air Force(USAF) to help further develop the engine.
由。。。生产AMCM.， 一个EOS Group据报道，公司制造定制添加剂制造机器，该组件是全球最大雷电竞充值的液体火箭发动机燃烧室3D在单个部件中印刷。发射器最初宣布于2019年2月在2019年2月开展突破性的航空航天组成部分。
Launching into space with 3D printing
Founded in 2017 in Brooklyn, New York, Launcher is an aerospace startup seeking to create an efficient rocket solution for delivering small satellites to space.
The company believes it has found an answer with its Rocket-1 launch vehicle. Standing at 20 meters (65 feet) in length, the Rocket-1 is designed to deliver satellite payloads of up to 773 kg (1,704 lbs) to low earth orbit. Launcher claims it is the best performance launch vehicle for the small satellite market, with the highest ratio of payload to rocket mass.
和许多人一样aerospace startups，3D打印正在发射器的外太空努力中发挥着关键作用。最初公司与EOS合作到3D打印基础E1验证引擎在2018年退出铜合金。E-1发动机是发射器的第一代液氧冷却燃烧室。然后，该公司于2019年开发了其液体氧气和煤油E-2发动机，并选择与AMCM合作以生产a3D印刷燃烧室发动机。

E-2的液体火箭发动机燃烧室是在其M4K机器上由AMCM打印的3D，EOS M400 3D打印机的改进版本。由铜合金制成，部件尺寸为860毫米（34英寸），出口喷嘴直径为410毫米（16英寸）。据报道，它构成了发射器的E-2发动机的关键部分，是小型卫星发动车辆的最高性能引擎。
E-2发动机的第一个全尺度测试火灾计划于Q2 2020，已经完成了成功的子级测试。共有五个E-2发动机将用于为火箭1供电;第一个为第一阶段，一个用于发射的第二阶段。为了帮助启动者E-2开发和测试计划，发射器在USAF授予1.5亿美元Space and Missile Systems Center(SMC)’s Air Force Space Pitch Day on November 5 2019, a grant scheme for innovation in aerospace.
Other private aerospace firms utilizing 3D printing to reach orbit include Elon Musk’sSpacex.. The company is using 3D printed parts to support its私人空间探索计划.相对空间是一家加利福尼亚州的航空航天公司，是另一个例子，因为它追求了世界上第一个完全3D印刷火箭. The firm recently announced the successful raising of1.4亿美元的资金, bringing the 3D printed rocket one step closer to a 2021 launch.
AMCM将展出全尺寸发射器E-2燃烧室样机Formnext 2019in Hall 11.1, Booth C49.
