How Space X is Printing 3D Rockets
In today’s video, we are going to tell you all about SpaceX’s 3d rocket printing program.
In 2014, SpaceX began using additive manufacturing to produce rockets parts at scale and sent its first 3D printed part to outer space. Now, in their mission to colonize Mars by 2050, the company is using 3D printing technologies, including Direct Metal Laser Sintering (DMLS), to print parts in days rather than months. SpaceX is building rockets that can be refueled and reused many times over thanks to the high-performance parts 3D printing produces
Selective laser sintering allows for multiple components to be printed in-house, as one unified part, in a matter of days. When an RUD occurs and the fault is found, engineers can create a fix using 3D modelling software, integrating highly complex parts into new rocket engines for test firing a few days later.
Using 3D printing also helps manufacturers reduce the weight of the complete rocket, as fewer nuts, bolts and welds are required to produce their complex structure. 3D printing is especially useful in manufacturing an engine’s complex regeneratively
cooled nozzle, which routes cool fuel around the hot engine to simultaneously cool the engine walls and preheat the cold fuel before combustion. Watch the video till the very end t do you know all about how this wonderful technology works
