Multi Color Filament Mixer

Here’s a model that allows you to create your own custom filament colors. This process involves printing a model that itself functions as 3D printer filament. You choose the colors to use and they are blended during the printing process to form a single, uniform new color filament. Once printed, this filament can be used just like standard filament to add custom colors to your 3D printing projects!

Note: This color mixer is designed to produce unique, uniform color filaments, rather than creating filaments with the changing colors and multicolor patterns typical of dual or dichromatic filaments.

How It Works:

To create your new color, choose from two to four colors to fill the designated slots. Depending on your choice and combination, you can achieve various color effects:

• Two-Color Blend: Achieve a balanced mix by using two colors in a 1:1 ratio, or create a dominant/subtle effect with a 3:1 ratio. For best results, alternate the colors in the four slots.
• Three-Colors: Mix three colors using a 1:1:2 ratio for dynamic and surprising outcomes. Avoid placing the same color in adjacent slots to maximize the mixing effect.
• Four-Colors: Experiment with four different colors. This is ideal for specific needs, though it may result in a darker, more muted tone.

Color Mixing Tips:

• Use only one slot for darker shades like Navy Blue or Black to prevent overpowering other colors.
• Light colors, such as light pink or white, are best mixed in a 3:1 ratio with darker filaments to enhance visibility.
• For equally dominant colors, alternate them in the slots for a more harmonious blend.
• Do you need some help in picking the filaments for mixing? Maker World user @Vobi has created a page for visualizing how filament will mix together.   https://jetpad.github.io/color-mixer/

Printing Guidelines:

• The resulting filament will appear as if the colors are still separate, but true blending occurs when the filament is re-fed into the printer.
• To avoid adhesion issues, especially with materials like PLA and PETG, consider using a Bambu Textured PEI Plate. Dedicate one side of the plate to each type of plastic.
• For optimal printing results,  ensure your printer bed is thoroughly cleaned before attempting this print to help prevent adhesion problems. This simple step can significantly enhance the quality and success.
