Choose infill filament

[MalcTheOracle]

You can fake it.

Force a particular colour for infill

Depending on the complexity of the model, you can achieve this with primitives or even complex model shapes turned into modifiers. For the purpose of this example, you model is a basic cube. Add a cube primitive as a modifier, resize and change location to match the infill portion of the model and then in the object panel set your choices for colour and anything else. For more complicated models, create a version of your model as suitable to occupy the infill sections, add it to the build pla…

It will take a long time to print given all the filament swaps.

A task best suited for the H2D.
