Creating separate outer shell / infill / support for multi material prints
Hello,
This is my first post to the forum. I couldn't find the topic already posted, so I've created a new one. If the subject is already covered in another topic post, please direct me to it! Thanks in advance.
I'm trying to learn how to create a separate outer shell for a multi material print, like a 3D scanned sculpture whose .stl has been published. Specifically, I'd like to print an object with an outer shell made of only of bronzefill PLA (or other metal/stone fill pla), with infill made of an ordinary PLA, and support material made from soluble material.
The idea is to limit the use of bronzfill (or other specialty) PLA, because it is more expensive, to the object's outer shell only.
I don't understand if/how this can be done in Slic3r or other slicer software, or if/how it has to be done separately in a CAD package before being imported to a slicer. It seems most tutorials/videos on-line deal with discreet parts of a multi material/color object being re-combined and printed, but not the case of just the outer shell being in a different material from the infill and support.
Thanks for your help.

One other trick: Put your most expensive filament in slot 5. Because of the way Slic3r orders the filament changes, the filaments in the two highest slots each get loaded on every other layer, cutting the number of times you purge with those filaments in half.
If you have two expensive filaments (i.e. metal fill and soluble), put them in slots 4 and 5.
