Multi-color and multi-material printing in the Cloud Slicer
Multi-color and multi-material printing in the Cloud Slicer
The Cloud Slicer can prepare prints that use multiple filament colors or materials when your selected slicer engine, machine profile, filament profiles, and account permissions support it. This guide explains how the multi-color tools fit together and which detailed guide to use next.
How multi-color works
Multi-color and multi-material workflows in the Cloud Slicer are built around filament slots.
Each slot represents one configured filament for the slice. The slot needs both a selected filament and a slicer filament profile, because the profile contains the engine settings used for G-code, such as temperatures, cooling, flow, and filament behavior.
After the slots are configured, you can use them in different ways:
Goal | Use |
|---|---|
One object, part, selected group, or plate should use one filament | Assign a filament slot |
One model needs different colors painted onto its surface | Color painting |
Supports, seams, or fuzzy skin need local control | Support, seam, or fuzzy skin painting |
The printer needs cleaner transitions between filaments | Wipe tower and flush volumes |
Start with the right printer and engine
Before setting up colors, choose the printer and machine profile you plan to slice for. Multi-color controls depend on the selected machine setup, nozzle setup, and slicer engine.
The slicer can only add more than one filament slot when the selected engine supports multi-material slicing. The paint toolbar also hides paint tools when PrusaSlicer is selected, so the visible tools can change when you switch engines.
Configure filament slots first
The Filaments section in the slicer sidebar shows the filament slots available for the current setup. Each slot needs enough filament information to be useful for slicing, including a filament and a filament profile.
When two or more filaments are configured, the slicer can use those slots for object assignment, color painting, and wipe tower decisions.
Assign filament slots for simple color layouts
For simpler multi-color prints, assign a filament to a whole model, part, selected objects, or plate. This is usually the fastest option when each object or part should use one filament.
If your account is restricted to one color per plate, the slicer uses the plate-level assignment path instead of per-object assignment.
Use color painting for one multi-color model
Color painting is for assigning filament regions on the surface of a single selected object. Use it when one model needs multiple colors without being split into separate parts.
Color painting requires the color paint permission and the multi-color-per-plate permission. The tool is not shown when PrusaSlicer is selected.
Paint support, seam, and fuzzy skin regions
The other paint tools are not multi-color tools, but they use the same paint-mode style of interaction. You can paint:
- Support enforcers or blockers
- Seam enforcers or blockers
- Fuzzy skin regions
These tools are useful when automatic settings get close, but you need local control on part of the model.
Configure wipe towers and flush volumes
When the slicer needs to switch between filaments, it may create a wipe tower. The Cloud Slicer shows a wipe tower helper on the plate when the current settings and filament use require one.
For Bambu Studio and OrcaSlicer, the filament sidebar can also show a flush-volume button when at least two filament slots are present and your account has permission to configure flush volumes. Select the real filament and slicer filament profile for each slot before recalculating flush values so the slicer has the material and profile data it needs.
