Color-change PLA can be printed like standard PLA. If you print with heated bed it is recommended to set the bed temperature to approximately 40-60 °C.

Due to all the different types of hot-end it's extremely difficult to give a temperature advice. Please consider our tips as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
