I'm looking for suggestions for 3D design software which support designing multi-material parts.

I will be printing on a multi-extruder machine based on RepRap firmware. The printer will handle the files when given a proper g-code file. Slic3r will produce a proper g-code file given the right input. STL seems to be single-material, so I am looking for something like AMF files, or any alternative.

My question is, what is available for 3D design software which will produce a geometry file which slic3r (or some other slicing software) will properly process? I'm not asking for opinions on which software is best.

I believe this is my first question in any StackExchange forum, so if I have trespassed on community standards, it was not my intention.

You do not necessarily need a specific design tool, you can use any tool you want to create your multiple material product. It is the slicer software that manages the materials by assigning the correct extruder. E.g. Cura is able to join 2 STL files that fit together and assign each part a specific extruder and thus material. Please read more here for instructions
