Im doing a thesis on how to 3D print BIM models.
At this stage Im studying the possibilities of exporting a STL or OBJ model with multiple colors or materials. Im not trying to get a full color model, Im trying to get a model with 2 different materials/colors that can be printed at the same time without separating elements with 2 nozzle FDM printer.
Is there anyway I can get a file for example with a material for the glass and another for the rest of the model?
