According to foreign media reports, 3D printing technology is gradually emerging, not only can print everyday equipment, but also can print out various DIY parts and even various weapons. Currently NASA researchers have developed 3D printed rocket engine components. The 3D printing technology currently involved in the rocket power system is still unknown and it is classified as confidential. Scientists believe that 3D printing technology will be applied to a large number of fields in the future. In particular, aerospace design and manufacturing are inseparable from 3D printing technology. NASA has confirmed that 3D printing technology can be applied to rocket engines to create high-performance machines. Components.
First ignition test, this technology not only reduces manufacturing time, but also saves costs
NASA's Glenn Research Center in Cleveland, Ohio, and the scientific team led by engineer Taylor Hickman have achieved phased results for rocket engine 3D printing, which may change the design and manufacture of rocket engines. Sacramento rocket engine manufacturer Aerojet also participated in the study. The engineers tried to use this technology 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 to manufacture the conventional components. The process is shortened more time, but the specific information concerning this technology is scarce, because U.S. law restricts the design transparency of rocket engines and prevents the outflow of this technology.
Jeff Haines, Project Director of Aerojet, believes that the test results are satisfactory. In the process of injecting liquid oxygen and hydrogen, the performance of 3D printing parts is perfect, and after using 3D printing technology, the manufacturing time is obviously 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 studying space 3D printing technology. Other commercial space flight operators are also testing related designs in an attempt to build an open source 3D printed rocket engine.
