NASA aims to bring the US industry to push along with the state-of-the-art 3D additive printing. It had just tested a rocket engine's crucial turbopump unit which consists of 3D printed parts. Mart Calvert, the design leadman of the Marshall Space Center stated that NASA together with its private partners is creating major innovations when it comes to the additive manufacturing arena. Most companies have said that the parts used for this fuel pump were so far the most intricate they have ever made with 3D printing.
Throughout the test, the 2,000 horsepower, 1,200 gallon per minute pump was sprint up to 90,000 rpm. That’s amazingly about ten times faster than a jet engine at take-off. It was then put into a rocket engine-type environment with temperatures of up to 6,000 Fahrenheit and as low as -400 degrees at the liquid hydrogen intake.
The test was a success for NASA and the information is being shared along with the official partner industries so that they can make parts that meet the standard of aerospace. The 3D printed pump consumes 45 percent lesser bits compared to a traditionally manufactured part and needs half the time to create. NASA's primary objective is to ultimately make use of such parts in engine designs like theSpace Launch System. It’s a project of the future which is believed that one day can bring human beings to Mars.
