How practical would it be to try to replace A10 parts with improved 3D printed parts?
I understand that even titanium is now available as a feeder for 3D printing.
At least we still have the repair manuals - for now.
We needed to replace the wings on the A-10s in the last decade.
It was cheaper for Boeing to design a brand new wing to meet or beat the same original performance requirements than to try to replicate the originals.
The A-10C re-wing and avionics upgrades have extended the life of the aircraft.
3D metal printed parts have some issues - sometimes they weigh more or aren’t as sturdy as regular machined/forged parts. 3D printed parts aren’t that widespread in aviation as of yet.
