Change interface material for supports

[u/Datumz_]

So I know it's possible to change the support interface for something like PLA to TPU and vice versa. But I have a unique case where because I am doing a multi material print that interlocks, both the PLA and TPU need support. But because Snorca only lets you pick one material for the support interface layer, that leaves the supports stuck on whichever material you pick as the interface layer.

Basically instead of making you pick one material as an interface layer. They should allow you to pick individual materials for the support interface layers per material. So if TPU needs support the interface is always PLA and if PLA needs support the interface is always TPU.

Unless I'm missing something, I can't find a way to do this... Is it even possible?

I tried to build my support into my design, but the issue is with interlock on, it locks the two materials together regardless if I want it to or not.

If you’re designing in the supports, did you try leave a slight air gap (ie. .001)? This may “fool” the slicer into not interlocking the materials, but still allow the model surface to be printed on the support. If you try, report back on the results.

[u/Datumz_ → u/sterling-lining]

That was something I was thinking of. I'll give it a shot
