IN a major first, American start-up Relativity Space is working on two different models of entirely 3D-printed rockets. Currently in the testing phase, Terran 1 is scheduled to be launched into space early next year.
Relativity Space's ambition is to set up a fast and autonomous 3D production system that could one day even help humans in their missions on Mars.
Faced with tough, established competitors such as SpaceX (a NASA partner) and Blue Origin, Relativity Space plans to set itself apart with its ability to build fully 3D-printed modules. The start-up is betting on a radically simplified production chain, capable of building a rocket with 100 times fewer parts than the competition, and in just 60 days.
Its 3D printing platform can print metal parts up to three metres in diameter and seven metres high. The 3D printer in question is equipped with an impressive robotic arm capable of printing these huge parts in a few days.
3D printing has many advantages, such as reducing the number of parts, but also boosting their reliability. Ultimately, the goal is to reduce costs and to offer equipment that can be reused several times. --ETX Daily Up
