Several of us have used FDM parts in our vehicles. Caleb had built a Stewart that that had a lot of FDM construction. In general, that technique is suitable for components that aren't subjected to high stresses. You may be surprised what a beating our tanks take out in the rough.
I can't imagine why someone would print their own servo or motor. There are too many reliable, low-cost alternatives out there that meet our needs. I have been using my 3D printer lately, but it was to build a plug for a turret fiberglass mold. It's been very slow going to prepare the plug!
