We compare 3 Comgrow PETG Rainbow 1kg listings from Amazon. Every listing is below, cheapest per kg first. Prices are checked every 4 hours and normalized to a true cost per kilogram. Rainbow filaments change color along the spool, so a single print shows several colors without a multi material printer.

Printing Comgrow PETG Rainbow 1kg

Comgrow PETG Rainbow 1kg prints on the PETG profile below. PETG is best suited to functional parts that need toughness and the light outdoor or higher-heat use PLA can't handle. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.

Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our PETG filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.

Nozzle Compatibility

This is an unfilled plastic, so it is not abrasive: a brass nozzle works and lasts, and so does hardened steel. With hardened steel, print about 5 to 10°C hotter.
