Bambu just released an update for the Bambu Studio app that gives users much more flexibility when it comes to color. According to the company’s X post, the Color Mixer Studio will let you combine two to three different filaments to create a totally new shade. Aside from that, you can also use it to print gradients across two colors, allowing you to give your 3D prints a unique look. This isn’t a new technique, and some have been experimenting with this method of color mixing for a few years now. However, Bambu acknowledged that it used Ratdoux’s approach, found on the OrcaSlicer-FullSpectrum fork available on GitHub, as the basis for the color prediction part of this new feature.
This color mixing feature is similar to the halftoning technique used in printing, wherein printers lay CMYK dots in patterns that vary in size and spacing on a flat surface to trick the eye into seeing new tones, hues, and shades. The difference here is that instead of using ink dots, Bambu 3D printers use different filaments to produce the optical illusion of a new color on a 3D surface.
