I'm wanting to start experimenting with Glock frames from a multi material unit. I have the Qidi Plus4 with the Qidi box which acts similar to the more popular Bambu X1C with AMS. What print orientation works well if you have the ability to switch filaments for support interfaces so they come out super clean? Also, what works well for that interface material? I hear PETG is good for PLA+ prints but I also hear to beware of swapping to filaments of different temps in the same nozzle. What would be a good interface material for PET-CF or PPA-CF or PAHT-CF?
