PVB as soluble support
hi i print minis and was thinking of getting an MMU for soluble supports, but BVOH seems expensive and i have high levels of humidity so it would be a pain if my filament dissolved on my shelf between prints, which got me thinking, could i use PVB as support material?
if so how would it impact print quality and how much does the waste product kill mother nature?
edit. i am aware that PVB also needs a drybox, but since it doesn't litterally disolve from water i'm guessing it is less of an issue for PVB
RE: PVB as soluble support
bvoh works fine. wouldn't the amount of IPA required to desolve supports on a reasonably sized print be expensive too? I've not used PVB so I don't know how quickly it dissolves in IPA, but since IPA tends to evaporate wouldn't you have to put the part in a sealed container with the IPA in order to have it dissolve?
Oh, and IPA is flammable.... especially 99% lol
My big grievance for solubles at the moment is that the wipe tower tends to not do well with solubles. I did find a kludge that works though. You can get a spool of BVOH from Prusa shop for less than 100 shipped to the us, including shipping.

@ssill2
another recommended i check out HIPS which should be even cheaper and able to disolve in lemon juice
RE: PVB as soluble support
as far as I understand it HIPS is primarily for ABS

RE: PVB as soluble support
i plan on printing the minis in ASA so should be fine
RE: PVB as soluble support
There you go. Sounds like hips is the way to go. I've only done about two prints with ABS, none with ASA, I do have some hatchbox lime green ABS I wanted to print my next prusa printer's parts in lol
