Some stuff absolutely can be more durable than factory. I got a Kevlar nylon mix I can print in.

Again.... Print em up, leave em in the sun, expose them to 140 degree and -20 degree interior temps and subject em to countless vibratory cycles of various amplitude and frequency for 1500 hours, and we'll talk about it in twenty or thirty years.
