Why Do Heat Set Inserts Loosen in PETG but Crack in PLA?
Heat set inserts loosen in PETG but crack in PLA because PETG tends to deform or creep under preload, while PLA is stiffer and more likely to fracture under radial stress.

Why Does PETG Lose Screw Torque Over Time?
PETG loses screw torque over time when the printed plastic relaxes under preload. This FAQ explains PETG creep, boss deformation, screw engagement, repeated assembly, vibration, and temperature.
Why Do Heat Set Inserts Fail in PETG Parts?
Heat set inserts fail in PETG parts when the surrounding plastic cannot maintain preload, boss support, or mechanical engagement under creep, screw torque, heat, vibration, or repeated assembly.
