Multi-color Purge Waste Estimator
Turn your slicer transition count and purge estimate into a practical material and waste check.
How the calculation works
Discarded purge = (changes × purge per change + tower material) × (1 − reused share).
How to use this result
Transition waste varies with color contrast, material compatibility, nozzle volume, and slicer settings. This tool does not guess printer-specific purge values; use the slicer transition estimate.
Example
A print with many swaps can consume more purge material than its visible model, which is why a transition count is more useful than a material-name copy page.
