According to the market understanding of 3D Science Valley, the RAMPT project is funded by the GCD program under the STMD of NASA. This is based on the joint efforts of NASA MSFC, GRC, LaRC and ARC.

         According to the understanding of 3D Science Valley, NASA 3D recently printed a rocket nozzle weighing about 2 tons through cooperation with DM3D and Auburn University. NASA's AM R&D project to improve the performance of liquid rocket engine.

        Auburn University and NASA are at the forefront of additive manufacturing research. They began to cooperate with DM3D about four years ago. At that time, they printed a nozzle about two feet in size, which looked very large at that time. Now, with the support of RAMPT project, the nozzle height being printed is five times higher than before, which is one of the largest 3D printing rocket engine components in history.

        The exact size of the full size RS25 nozzle liner made of approximately 2 tons of additive is 111 inches high and 96 inches diameter. Large parts were manufactured in a few months - compared with traditional manufacturing technology, the processing time was reduced by more than 50%. The construction period has been shortened by 2 to 10 times.

     It is hoped that the successful demonstration of printing large rocket engine components will open the door for the manufacturing of large metal additives, benefit the rapidly developing commercial aerospace industry, accelerate innovation and bring greater benefits to social development.
