I print a lot in ABS and recently more in ABS-GF. I find the Bambu X/P printers allow ABS to be printed with ease as long as you let the chamber preheat.
Here is an ABS part I regularly print (and dip). This part threads into a mating ABS printed part.
Here is an example of a ABS-GF part I’ve printed that is subject to relatively high stress and strain. It performs better than the same part printed in regular ABS.
If the durability and heat resistance works for your application I would suggest trying the ABS-GF and it’s cheaper and IMO easier to print than PA6-GF.
Clough42 has a video recently about this filament and detailed how it solved the issues he was having with a large part that was causing issue. Starts about 19min mark.
I do use the default settings other than changing the infill pattern to something non crossing.
