Multi-Color 3D Printing
Multi-color 3D printing is the process of creating multi-colored physical objects in a single print run using automated filament switching systems (like the Bambu AMS or Prusa MMU), multi-nozzle tool changers, or IDEX dual extruders.
Every additional color on a plate adds purge volume and print time. The estimator charges multi-color runs a per-run fee plus the purge fraction, so a four-color part can cost meaningfully more than the same geometry in one color.

Single-nozzle multi-color systems must flush the previous filament color out of the hotend before extruding the new color. Slicers generate a prime tower on the build plate to stabilize nozzle chamber pressure after every color swap.
Minimizing Purge Waste
Techniques to reduce filament waste include Flush into Infill (purging transition colors into internal hidden spaces), Flush into Objects (printing a secondary sacrificial model), and optimizing color distribution across layers.
Quoting Multi-Color Print Jobs
Because every filament swap adds 40–90 seconds and 0.5g–2g of purge waste, multi-color prints take significantly longer and consume more material than single-color jobs. Cost estimators apply per-color fee multipliers to cover this overhead.
