In what is possibly a first, the MIT Rocket team have successfully tested a fully 3D printed solid rocket motor. The motor which included everything bar the propellant was printed from Nylon.
Be interesting to know the cost, let’s say vs a hobby motor of the equivalent size.
Check out the video below and read the full write-up here.
Video Caption: Using Markforged Onyx Nylon a 2 piece, completely 3D printed rocket motor was fired for the first time by MIT Rocket Team on April 21.
Without the generous support of Markforged this project would not have been possible.
