Multi-color Purge Waste Estimator

Turn your slicer transition count and purge estimate into a practical material and waste check.

Inputs

Use the slicer transition estimate or a measured amount.
Only count material that actually replaces otherwise-needed model material.

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.
