After they ran out of replacements parts for a complex gearbox housing used on the B-52 and the AWACS, the US Air Force contracted with Renaissance Services, where we provided the reverse engineering, casting design, and prototype parts to Tinker Air Force Base.   This was a process that started with reverse engineering of the old TF33 engine parts and the creation of a complete modern technical data package (TDP).  The TDP was then used to additively manufacture tooling for the production of the casting, which was followed by the machining of the part as well as the fabrication of the subassembly.

Here is the article link to the successful piece in the Tinker Air Force Base news.
