Ok so normally I never use models with supports as I hate the finish it leaves. I just want to print and have the model be perfect. But now there are dissolvable materials for support and the Support Filament from Bambu.
So I saw that you can print an interface layer with the expensive support material and use cheap PLA as the main part of the support.
So my question is, once the support is removed does it still leave a crappy finish on the part like usual?
If so should I use dissolvable support material and when designing my parts I add in my own support interface layer like it’s a different color so it prints like it normally does and then just dissolve the part and bam perfect finish?
Using a “support filament” will lead to a better appearance, but maybe not as good as soluble. My experience with it has been good.
If you are designing for yourself, tell Bambu Studio that you are using soluble support filament for the interface, and it will adjust settings to give you a great finish surface.

Dissolvable and dedicated support interface filaments will produce the same results. The only benefit dissolvable provides is that you can remove supports from areas of a print that are mechanically inaccessible (you can’t pull the support material out through the available openings).
The dedicated support filament will fall away from the print, or at worst, come off with a gentle tug.
PETG is what BBL is using for PLA support (and vice-a-versa). You don’t need to pay for special material. For most filaments, there are a few other filaments you can use for support interfaces. Nylon works with ASA, for example.

Ok interesting. Thanks to both of you.
