What makes PETG the right choice for parts that take a knock?
PETG is a tougher polymer than standard PLA. Instead of cracking along the layer line it yields and flexes under impact, so brackets, clips, jigs and holders survive being dropped, stacked and handled. It also takes up far less moisture, which matters when a spool has been open in a damp workshop for weeks. The trade-offs are a softer, slightly glossier surface than PLA and a lower heat ceiling: for parts in sustained heat, switch to ABS or ASA. The recorded nozzle window for this grade is 230-260 °C.
