Here’s a model that allows you to create your own 4-color filament. This process involves printing a model that itself functions as 3D printer filament. You choose four colors to incorporate into the model. They are fused during the printing process to form a continuous, multicolored filament strand. Once printed, this custom filament can be used just like standard filament to add a personalized touch of color to your 3D printing projects.

When used in your 3D printer, the 4-color filament exhibits unique characteristics similar to commercial dual and tri-color options. Depending on the arrangement of colors and the orientation of your print model, you can predictably influence where colors appear on your final print. For example, you can anticipate your colors to show up in consistent bands throughout your printed model, blending from front to back and right to left. This arrangement offers a degree of control over the visual outcome, allowing for creative and stunning effects in your printed objects.

Printing Hints

I highly recommend using a Bambu Textured PEI Plate if you do not already have one. Utilize one side of the plate exclusively for PLA filament and the other side for PETG. This prevents adhesion problems caused by residual contamination from incompatible plastics.

For optimal printing results, also ensure that your printer bed is thoroughly cleaned to prevent additional adhesion problems. These simple steps can significantly enhance the quality and success of your prints.

Filament Examples

LARRY the tiny Dino is the featured subject showcasing the quad-color filaments.

The first Larry was printed using four colors.

• Bambu Lab PLA Metal - Iridium Gold Metallic
• Bambu Lab PLA Matte - Ivory White
• Bambu Lab PLA Matte - Lemon Yellow
• Bambu Lab PLA Matte - Mandarin Orange

Although this allows for four different colors, the next Larry is only using two colors and alternating them in the four color slots.

• Bambu Lab PLA Metal - Iridium Gold Metallic
• Bambu Lab PLA Matte - Dark Blue

This Larry also employs two colors. I chose yellow for three of the color slots and blue for the remaining one. Light colors such as yellow, pink, or white can be easily dominated by darker shades, so allocating three of the four slots to a lighter color can be advantageous.

• Bambu Lab PLA Matte - Lemon Yellow
• Bambu Lab PLA Matte - Dark Blue

And here is a Larry with three colors. White occupies two slots, sandwiched between red and navy. White blends seamlessly into the other two colors, subtly lightening the navy and red rather than standing out on its own.

• Bambu Labs Matte Scarlet Red
• Bambu Labs Matte Dark Blue
• Bambu Labs Matte Ivory White

 Happy printing!
