According to foreign media reports, 3D printing technology is gradually emerging. It can not only print everyday equipment, but also print out various DIY parts and even various weapons. At present, NASA researchers have developed 3D printed rocket engine components. Currently, the 3D printing technology involving the rocket power system is unknown, and it is classified as confidential. Scientists believe that the future of 3D printing technology will be applied to a large number of fields, especially the design and manufacture of aerospace are inseparable from 3D printing technology. NASA has confirmed that 3D printing technology can be applied to rocket engines to produce high-performance machines Components.
NASA ’s Glenn Research Center conducts the first ignition test of a 3D printed rocket engine, which not only reduces manufacturing time, but also saves costs
The NASA Glenn Research Center is located in Cleveland, Ohio. The scientific team led by engineer Taylor Hickman has achieved staged results of rocket engine 3D printing technology. This research may change the design and manufacture of rocket engines. Sacramento rocket engine manufacturer Aerojet also participated in this research. Engineers tried to verify whether 3D printing can be applied to the production of precision rocket engine components. For example, in the manufacture of engine nozzle components, 3D printing technology is used compared to traditional manufacturing. The process shortens more time, but there is very little specific information about the technology. This is because US law limits the transparency of rocket engine design and prevents the technology from flowing out.
Jeff Haynes, the project director of Aerojet, believes that the test results are satisfactory. During the injection of liquid oxygen and hydrogen, the performance of the 3D printed parts is perfect, and after using the 3D printing technology, the manufacturing time is significantly shortened. It took only 4 months before and after, and the cost was cut by about 70%. NASA is not the only institution that is researching space 3D printing technology. Other commercial space flight operators are also testing related designs, trying to create open source 3D printing rocket engines.
