What brass heat-set inserts are, the M2 to M5 size families with hole and wall figures, the iron temperature rule, and the 181 kg M3 pull-out from CNC Kitchen's test.
AnswerHardware
CNC Kitchen's measured pull-out loads for M3 heat-set inserts in PLA: 181 kg for Ruthex, 157 kg for eBay inserts, 39 kg for cheap ones, and how hole size changes it.
AnswerHardware
CNC Kitchen's M3 test in PETG: a bottom-pocket nut held 166 kg against 119 kg for a heat-set insert, but the insert took more torque. When each fastening wins.
AnswerMaterials
Iron temperature per material for heat-set inserts: about 225 °C for PLA, 245 °C for PETG and 265 °C for ABS, from CNC Kitchen's printing temperature plus 10 to 20 °C.
AnswerHardware
Yes: brass heat-set inserts hold in PETG at an iron temperature of about 245 °C, and the part stays rigid to a glass transition near 80 °C. Expect stringing from the tip.
AnswerHardware
A soldering-iron procedure for square, flush heat-set inserts: iron 10 to 20 °C above printing temperature, melt about 90 % of the way, finish with a flat tool.
AnswerTroubleshooting
Reheat a tilted insert at 20 °C above printing temperature (240 °C for PLA) and press it flush, or pull it out on a screw in about 10 seconds; drill 5.6 mm for an M4.
