What is PETG, and why print functional parts in it instead of PLA?
PETG is a glycol-modified PET made for FDM printing. Against PLA it is tougher and far less brittle, bonds more strongly from layer to layer and shrugs off moisture and common chemicals better, which is why it suits jigs, brackets, guards and bins that get clamped and dropped. It prints in a 230-260 °C nozzle window and needs no heated chamber, so it runs on ordinary open-frame machines. For parts held in sustained heat in service, choose ABS or ASA instead.
