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

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
