Print with dozens of colors: Our new open-source ColorMix for PrusaSlicer
Prusa Research has introduced an open-source color mixing model called Prusa ColorMix for 3D printing. This model allows users to print with a wide range of colors using just five filaments, enhancing the capabilities of multi-material printers. The initiative is rooted in community collaboration and aims to simplify the color printing process.
- ▪Prusa ColorMix enables printing with dozens of color tones on multi-material printers.
- ▪The model is based on a calibrated color mixing system that connects to real material data.
- ▪It uses a method similar to traditional 2D printing, alternating colors by layer to create the desired hues.

Print with dozens of colors: Our new open-source ColorMix for EasyPrint and PrusaSlicer This article is also available in following languages: Prusa Research May 26. 2026 Estimated reading time: 12 minutes For the past few months, the 3D printing community has been poking at a very interesting question: what if a multi-material printer were not limited to the colors physically loaded on it? And we must say it right now: This is a really awesome way to expand your 3D printing capabilities! In this article and video, we’ll show you how to print with dozens of color tones on any multi-material printer and how we made that possible. It’s a proper deep dive, so get comfy – you’re in for a ride! Let’s talk about the community – because that’s where it started.
