Full Spectrum is a fork of the Snapmaker Orca slicer. It includes support for virtual mixed-color filaments designed for the Snapmaker U1 multi-color printer with independent print heads.

I designed some objects to test the results of mixing different filaments and the effects of some parameters. When mixing different filaments, color is not the only factor that influences the results. The color of the base material, the amount of pigments added and therefor the intensity and opacity or translucency of the color makes a big difference. But even if you use the same filament the result will differ depending on the angle of the print and the layer hight.

None of these test prints are needed to get started with Full Spectrum. They just help to get a feel for it and test specific parameters.

The colors of my test objects are not painted on in the slicer. The objects consist of several parts and can be manipulated without a problem. You can move them, split them, enlarge or shrink them and you can even use moddifiers without the need to repaint anything.
2D printers normaly use CMYK (cyan, magenta, yellow and black) to print normaly on a white canvas. As we don't have a white canvas and only 4 colors I defaulted to CMYW. You can change the colors as you wish but you don't have to. Just send the files to the printer and assigne your loaded filaments whichever color they have.

The different files:
The hexagon shows all 15 possible colors you can mix when only using each color once or not at all. The numbers show which colors were used for mixing (12 means color 1 and color 2 are mixed).

The tetraeder only shows 14 of the 15 colors. The mix of 1, 2, 3 and 4 would have been inside of the tetraeder. The 4 colors used for mixing are in the corners so you directly see how each color is mixed together. This object might be difficult to print. It has to be in this orientation so that all sides have the same angle. I hope my selfmade support works for you.

The gradient shows a mix of only two colors but with different ratios. It starts with the one color than a mixture of 3 to 1,  2 to 1,  1 to 1,  1 to 2, 1 to 3 and finaly only the other color. It should help finding the right ratio for two specific filaments. 

Angle 10 and angle 15 print one (mixed) color on planes angled from 0° to 90° in increment of 10 or 15 degrees. Test it with different layer hights to see how visible the mixing-lines get. It very much depends on the angle, the layer hight, the different colors and very much the translucency of the filaments. When printing mixtures with a ratio other than 1 to 1 the lines may get more visible as well.
