Want to create beautiful prints with a rainbow effect? It's easy with the silk rainbow filament from SUNLU. This coil contains filament in seven different colours: red, orange, yellow, green, blue, purple and pink. The roll starts at one of these colours and changes to the next colour of the rainbow after about 15 meters. The multicoloured PLA filament is easy to print with (without heated bed) and provides a silky gloss finish.
