Welcome to the colorful world! Multi-Color printing is one of the most amazing features of Bambu Studio. After importing a model, you can complete a colorful model in just several steps:

  1. Add filaments according to the colors that you want. If you want to use support filament for better overhang quality, please also add it.
  2. Colorize the model.
  3. Slicing & Print.

Manage Filaments in a Project

Filaments in a project are all listed in the Filament block of the left sidebar.

In Filamemt block, you can complete all filament management tasks:

  • Add a filament
    Click the ➕ button to add a new filament to the project. The newly added filament will be appended to filament list.
  • Delete a filament
    Click the ➖ button to remove the last (with the largest index).
  • Set colors/types of filaments
    Set the filament type and color for each filament. When a printer is connected, you may quickly copy the color&type from an AMS slot.
  • Config the visibility of filament types
    You may configure the visibility of each filament type in the Filament Selection dialog by clicking ⚙. Only selected filament types are visible in the combo box’s dropdown list.

The filament list is also saved in the 3mf project file and will be restored when loading the 3mf file.

Colorize Your Model

Bambu Studio provides versatile colorizing tools for various types of models.

Set filament for object/part

You can bind a filament to an object or part in multiple ways:

Select filament for objects/parts in the object list on the left sidebar

Right click target object/part and select filament from the context menu

Select the object, and use the shortcut key 1-9 to bind the corresponding filament to selected objects/parts

Tips: If you can’t find the object list, you need to switch to Global/Object mode here 


Paint on an Object

Bambu Studio provides a powerful Color Painting tool. This tool allows you to paint almost anything in different colors on the selected object.

The left image shows the original model and the right image shows the painted model.

Set Slicing Parameters for Multi-Color

For a single extruder printer, each time filament change happens, a small amount of filament is left in the extruder. As the new filament is loaded, it starts pushing the old filament outside of the extruder & nozzle. During this time, you’ll see a gradual change in the color of the extruded filament.
Thus, to make sure the model’s color is not messed up, it requires enough new filament volume (flushing volume) to flush out the old filament. But too much flushing volume means wasting filament and print time.

Features described in reduce-wasting-during-filament-change introduce how to print the desired color effect and reduce the wasted filament.

When printing with AMS, the filament list in the sliced project does not necessarily need to be exactly the same as the AMS filament list.
When sending the print task, the filament mapping from the slice project to AMS is automatically built according to the color and material type (PLA/ABS/PC…)

The automatic mapping matches filament with the same type and similar color.
Normally, you don’t need to modify anything. But if you are not satisfied with the result of the automatic mapping, then modify it manually.
