This engineering reference explains how edge distance affects heat set insert strength in 3D printed parts, including corner cracking, insert spin, pull-out failure, and thin wall design risk.
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 Do Heat Set Inserts Crack PLA Bosses?
Heat set inserts crack PLA bosses when brittle printed plastic cannot absorb radial stress from insert installation, tight hole sizing, thin boss walls, edge distance, or screw load.
Why Do Heat Set Inserts Fail When the Hole Is Too Small?
Heat set inserts fail when the hole is too small because the insert forces too much plastic outward, creating radial stress, boss cracking, deformation, poor alignment, or layer separation.
