Multi-Material / AMS Planner
Plan your filament slot order, estimate purge waste, and get tips for minimizing material use in multi-color and multi-material prints.
Enter your filament colors (name or hex) and approximate darkness (0 = white, 100 = black). The planner will recommend a loading order to minimize contamination bleeding between slots.
| Transition Type | Recommended Purge | Notes |
|---|---|---|
| Light → Light | 40–60mm³ | Low contamination risk |
| Dark → Light | 100–200mm³ | Requires more purge to clear pigment |
| Light → Dark | 40–60mm³ | Dark covers contamination easily |
| Dark → Dark | 60–100mm³ | Depends on color contrast |
| Any → White | 150–300mm³ | White requires maximum purge |
| Different material | 200–400mm³ | PLA→PETG etc. needs full flush |
Order from light to dark in your slot sequence. Most printers flush into a purge block or tower — going light → dark means the "contaminated" purge is a dark color where residue is invisible.
Minimize swaps by reorganizing your model. In your slicer, group same-color regions near each other in Z height to reduce the number of transitions per layer.
Use infill as purge (Bambu). Enable "Purge into infill" where available — this uses infill to flush instead of wasting material into a purge tower.
Re-use purge waste. Purge blocks are often structurally sound — collect them and use as filler material for projects that don't require specific colors.
