Seven semi-translucent Prusament PLA filaments designed to blend into more than 100 colour shades on a multi-tool printer.

The ColorMix filaments are built for the Original Prusa XL 5-toolhead and CORE family printers with the 8-tool INDX upgrade. Their semi-translucent formulation lets neighbouring colours mix optically, giving smooth blended tones rather than visible stripes of alternating layers. Using ColorMix in PrusaSlicer or EasyPrint, the seven spools combine into around 80 colours plus 25 greyscale shades. Want brighter, more saturated, opaque colours instead? Consider the Prusament PLA CMYK Bundle.
