I am curious about the longevity of a PLA printed part used in a commercial application. It would be a mounting bracket installed in an industrial enclosure. The internal cabinet temperature would be less than 100 °F, and have an internal air circulation fan to keep the control PLC cool.
It would be in a steel enclosure, in an industrial environment, with no sunlight or UV exposure.
Would the PLA hold up over time, or have any issues with delamination or brittleness?
