Different Material for Support Interface
I have a MK4 / MMU3. I’d like to print the support interface layer from PLA if the main object is PETG (or vice versa). This is to facilitate a clean and easy breakaway of the support material from the main object.
How do I do this using the Prusa slicer?
Thanks,
Tom

RE: Different Material for Support Interface
Use the Configuration Assistant to install the Mk4S MMU3 profile for your nozzle size. To slice, select the Soluble Interface print profile.
I found Soluble Interface works okay if you have pretty horizontal contact surfaces. For angled surfaces, the interface material usually slides off the supports
