Stress test supports. PLA printing with PETG interface supports
I created a test to try printing in PLA (in white in the photos) with interface supports in PETG (in black in the photos). From my results I believe that PETG interface layers resolve very well the defects that are created when using supports.
I recommend modifying and then saving the print profile. I made the print quickly (0.2 mm layer) but if you want you can set the same parameters with a lower layer height.

the part in contact with the PETG support is perfect.

now the photos of the settings to put in the slicer. Please note that I put the PETG in place 3 of the ams (if you change it it must be reported in the “filament for supports” section

FLUSCHING VOLUMES
it is necessary to increase the filament change between PLA and PETG to the maximum (number 800). in my case I printed with PLA in place 2 and PETG in place 3
Excellent. The weird shapes and impossible overhangs are a great way to test support relatively quickly. I used PETG as an interface material, and the overhangs were perfectly smooth, which was wild to see.
