- InssTek printed a "Multi-Material 3-ton Rocket Nozzle" with our research partner, Korea Aerospcae Research Institute (KARI).
- The first firing test of the multi-material rocket nozzle confirmed the possibility, and the second test(20sec) verified the performance of the rocket nozzle.
- This rocket nozzle consists of 2 different materials. The inner part with cooling channel is made with Al-Bronze(Cu based Alloy), and the outer part is made with Inconel 625(Ni based Alloy).
