Reducing the waste of filament and print time while printing multiple filaments with a single hotend. There are several systems available to emulate a multi extruder with a single extruder also printers with several printheads and tool changers.

Let's get started

The 3MF folder contains ready to slice and print models for prusaslicer and bambustudio. Choose 4 filaments and go for it.

The model is a small square, just 8x8cm and 0.8 to 3.2 mm in thickness only a few grams of filament is needed. Just 4 to 16 layers and only 48 tool changes are needed.

Layer Height: 0.2 mm, 100% infill done with top/bottom layers, each module has 4 layers.

You can save this prints as filament samplers / swatches that tell you how one filament goes over to any other one, by time you get a collection of all your filaments.

Help needed

It would be cool to add more data from other printers and filament changing systems.
