3D Printed Hypersonic Missile Nose Cone Made on Hybrid CNC Machine

CORRECTION: I say "wire arc" in this video, but that is incorrect. Mazak uses a hot wire process. -Pete
A Mazak hybrid CNC machine tool using deposition for metal additive manufacturing was used to make this solid steel missile nose cone, which was also machined to tolerance as part of the same cycle. The part demonstrates the potential role of hybrid machine tools for low-volume production of parts that might otherwise require long lead times for forging, casting or assembly. The part seen here is a proof of concept, but based on this demo, the Air Force ordered a 3D printed missile nose cone to its own specifications which has been used in flight testing.

Thanks for the video - I saw something a like this a few years ago from a company called Titomic using a cold spay process, but I haven’t seen much online about that process. Most of the large-scale 3D metal printing seems to be wire-arc deposition. It would be interesting to see a comparison between the two processes (or any others) and their pros and cons.

Minor correction- The Mazak machines highlighted in this video use a laser hot wire process. Not a wire arc process :)

That is a meaningful distinction. I apologize that I misspoke. Thank you for the correction!

ORNL's MDF really is an incredible facility. An AM enthusiast could get lost in there!

We have designed and built such a machine in 2022 in Turkey, we are looking for export partners
