    I’ve also had problems with PLA prints delaminating and becoming brittle over time, especially if it’s being flexed or exposed to sunlight. Some PLA’s are worse than others with this, though.

    I use PETG for anything I want to last a long time.

        If you’re willing to get into annealing, I’ve had good service from annealed HTPLA in high temperature/humidity and even overpressure environments. I’m three years into a build that gets multiple hours of use in such conditions a week and it’s held up fine. There have been other problems, but nothing related to bad behaviour out of the HTPLA.
