Bambu Color Mixer Studio - 13 Swatch Test Palette

Showcase the incredible power of the Bambu Studio Color Mixer with this organic 13-swatch test palette. Designed to look like an artist's palette, this model serves as a perfect demonstration object for the new virtual filament mixing capabilities.

While you can guess how mixed filaments will look on your screen, printing this physical gradient transforms your digital predictions into a tangible, accurate color swatch. The best part? You only need 4 physical filament spools in your AMS to create this entire 13-color spectrum!

Key Features:

• Color Showcase: Ideally designed to demonstrate the mixing properties of different filaments. By blending just four base colors, you get a stunning, seamless transition across the spectrum.

• Smart Geometry: Features 13 distinct 3D domes on a smooth, organic base plate. The curved geometry of the domes highlights how light hits your newly mixed colors from different angles.

• Intuitive File Setup: Every individual body in the file is specifically named to tell you exactly how to mix the colors right inside the slicer.

• Universal Compatibility: While designed for any color combination, this model prints perfectly in standard materials like PLA, PETG, or ABS—just ensure all mixed filaments are of the exact same material type.

How to Print:

• Software & Hardware: You must use Bambu Studio version 2.5.3 (or newer) and a multi-color setup like the Bambu Lab AMS or AMS Lite.

• Color Assignment & Naming Guide: I have named each individual body in the 3D model to make applying the correct mixing ratios incredibly easy. The letters correspond to your 4 base colors:

  • B = Blue

  • Y = Yellow

  • R = Red

  • W = White

  • How to read the ratios: The letters dictate the percentage of the mix. For example, a dome named RRB means you need to set a mix of 2/3 Red and 1/3 Blue. A dome named YW requires a 50/50 mix of Yellow and White.

• Base Plate: We recommend assigning a neutral solid light color (like white, light grey) to the flat base plate to make the newly mixed colors pop without visual interference.

• A Note on Filament Waste: Be aware that generating 13 different blended colors on a single-nozzle system (like a standard Bambu printer with AMS) requires a massive amount of filament swaps per layer. This inevitably results in a significant amount of purge waste. Printing this type of mixed-color gradient on a dual-nozzle or multi-toolhead system is vastly more efficient and produces considerably less waste.

• Purge Volumes: Crucial step! Make sure your flushing volumes are properly calibrated. Because this model uses up to 13 different color definitions, insufficient purge volumes will cause the colors to bleed into each other during toolhead changes.

• Layer Height & Settings: While a standard layer height of 0.2mm works, using a smaller layer height (e.g., 0.12mm or lower) is highly recommended. Thinner layers allow the alternating filament colors to physically blend together much more smoothly, resulting in a cleaner, more convincing mixed color.

• Prime Tower: A prime tower is highly recommended to catch residual filament after color swaps and ensure clean layers on the domes.

• No Supports Needed: The geometry is optimized for FDM printing with self-supporting curves on the domes. You can print this model completely without support structures.
