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.
