@whitequark I've only ever used PLA, PETG, and nylon for prints. PETG is my favorite of those for my own projects. At work I use PLA for prototyping and throwaway parts (e.g. we needed some caps for some aerosol cans that were missing their original caps and we wanted to protect them in shipping, five minutes to design in FreeCAD and 20 minutes to print each).
I use nylon for a floating bearing I designed to replace the obsolete mass produced bearing used in equipment we sell, it has to be nylon so it can slip and spin in the hinge without breaking down, while still structurally sound enough to not collapse and break under lateral pressure.
