A 500 mm titanium rocket ring without buying a 500 mm titanium plate. 🚀
That’s the manufacturing challenge tackled by the Aerospace Systems Research Institute (ASRI) at the University of KwaZulu-Natal, working with Petrawell and integration partner AMT3D.
For the STEVE sounding rocket, the team needed large-diameter titanium radax joint rings. Rather than machining them from expensive titanium plate and removing most of the material as waste, they investigated an additive manufacturing approach.
The solution was a clever hybrid process:
🔹 Print four titanium segments on a Meltio M600
🔹 Assemble and machine them onto a 600 mm steel build plate
🔹 Complete the ring using a Meltio Robot Cell with an inert atmosphere bubble
🔹 Finish the components through machining, inspection and assembly
The approach also creates a repeatable manufacturing method that could potentially be applied to larger components for ASRI’s future launch vehicle programme.
