Printing Multi-material Objects
If a multi-material AMF le already exists, because the CAD program can
export such a format, then this can be loaded into Slic3r in the usual way.
The mapping between object materials and extruders is sequential, i.e. the
rst material is assigned to the rst extruder, etc.
Generating multi-material AMF files
Slic3r has the feature to combine multiple STL les into a multi-material
AMF le.
• Split the original design into the separate parts within the CAD
program, and export each part as STL.
• Within Slic3r, choose Combine multi-material STL files... from
the File menu.
• When prompted with a le dialog, choose the rst STL, which will
be assigned the rst material (and hence the rst extruder). Click
Open to be prompted for the next STL, and so on until each STL is
assigned a material. To signal there are no more STL les, choose
Cancel.
• The following le dialog prompts for the location and name of the
AMF le.
Once generated the le can be loaded and printed as described above.
