成立于2017年，Launcher正在使用3D打印来开发液体氧（LOX）/煤油火箭，以将卫星运输到低地球轨道中。现在，随着3D印刷铜合金E-1发动机的成功测试，该公司在为期10年的旅程中又一步，为寻求商业卫星发射的企业家提供低成本解决方案。
商业航空航天
In recent years, the aerospace industry has seen an increased interest from companies seeking to provide commercial services, such asprivate spaceflight和satellite launches for communications, navigation, weather forecasting, and telescopic study.
Launcher, like other aerospace startups of its kind (SpaceX，Virgin Galactic，蓝色起源和Aerojet Rocketdyneto name a few) is employing 3D printing on its mission to orbit.
With additive manufacturing, Launcher is able to develop engines at a faster rate than is would with traditional manufacturing. In the past two years in fact, the company has successfully conducted at least 8 hot fire tests of 3D printed thrust chambers made from Inconel, and now copper. Coupled with LOX fuel, 3D printing is also helping to make engine development more cost-effective. The company is headquartered in New York City, and based at新实验室, a technology incubator.
EOSrocket engine 3Dprinting
2018年6月,发射器确认生产partnership with leading 3D printer providerEOS。Through EOS, Launcher was able to 3D print its latest E1 proof-of-concept engine out of copper alloy which performs better than Inconel in terms of cooling capabilities vs. combustion.
E1铜发动机打印在3DEOSM 290系统。在布鲁克林海军院子的测试射击中，发动机能够在30秒内承受最高的LOX温度。从这一点开始，发射器团队将能够逐步增加燃烧压力，以达到其1,400PSI和下一代E-2发动机的飞行目标。
