Application Of New 3D Print Technology

On August 31, 2014, NASA engineers just finished testing a 3D-printed rocket injector in a research effort to improve the performance of a component of a rocket motor. Because of the mixture of liquid oxygen and gaseous hydrogen in the injector, the combustion temperature here can reach 6,000 degrees Fahrenheit, or about 3,315 degrees Celsius, producing 20,000 pounds of thrust, or about nine tons. This test proved the feasibility of new 3D print technology in the manufacture of rocket engines. The test took place at NASA's Marshall Space Flight Center in Huntsville, Ala., where rocket engine testing conditions are well established, and engineers verified the performance of practical 3D print technology parts in an ignition environment.

The use of useful 3D print technology can reduce the complexity of manufacturing and create a 3D image of the injector in a computer. The 3D Printing materials are metal powder and laser. At high temperature, the metal powder can be reshaped into the shape we need. There are dozens of ejectors in a rocket engine. It takes precision to build similar-sized components. If tested successfully, the technology will be used to build the RS-25 engine, which will be the main power for NASA's future Space Launch System. The rocket could carry astronauts beyond low-Earth orbit into deeper space. Marshall engineering director Chris think useful 3D print technology in the center of the application is only the first step in the rocket engine fuel injector, our purpose is to test how the practical 3D print technology parts can completely change the rocket design and manufacturing, and improve the performance of the system, more important is can save time and cost, less prone to failure. In this test, two rocket ejectors fired for five seconds each, creating a complex geometric fluid model that allowed oxygen and hydrogen to mix well at a pressure of 1,400 pounds per square inch.

On October 11, 2014, a team of British enthusiasts created a rocket using practical 3D print technology, and they are ready to launch the world's first printed rocket. The team presented the world's first 3D-printed rocket to the media at its London office. Team leader Haynes said that with new 3D print technology, it is not difficult to create highly complex shapes. Even if the design prototype needs to be modified, the printer will adjust accordingly as long as the computer-aided design software is modified. This is much more convenient than traditional manufacturing methods. Now that NASA is using new 3D print technology to make rocket parts, the future of 3D printing is very bright.
