Water Soluble Filament for use in AMS?

Just curious if anyone has tried any water soluble filament for support for complex prints? Wondering if they would go through the AMS at all.

I’ve tried this last week, with Innofil Innosolve. It didn’t work. I got 3 nozzle jams, probably because of heat creap. With every try the first 2 filament swaps went okay, but with the third swap the Innosolve got stuck in the nozzle. The X1 wasn’t able to retract the filament.
I had more luck with the support filament from BL, which seems to be the same as the Polymaker support filament.


Thanks for sharing! I appreciate being able to learn from others mistakes instead of my own! :wink:

I got some very good success both in printing and use of AMS with Verbatim BVOH. Sadly it also is very expensive, but if you use it only for interface layer it is well worth the money and lasts quite a long time. Just submerge the stuff under water and the supports come off super easy. No problems with Nozzle clogs, AMS feeding or problems with layers not sticking.



Like this stuff?

Exactly this stuff! Well, almost, mine is not 2,85mm as your amazon link, but the normal 1,75mm size.
Got it here:

And buy a toothbrush too, it helps to get the last remains off SO much faster then waiting for them to disolve on their own :slight_smile:


Perfect! Thank you for the link.

Is the stuff Bambu sells water soluble? I print 100% PLA and just flush to supports on every print or if single filament printing use whatever I’m printing with. So, I have no experience with support materials.

No it is not. It just does not bond strong so it separates easily.

Not the slightest water soluble. I submerged it for several hours and it did not show even any hints of deforming or softening.

If you are interested in water soluble support for PLA, the material you want to look at is PVA.

I have used this sparingly in the past, but have not needed it since getting my X1C

PVA in my experience is great when you need supports in an area that is not really accessible after printing to get out the supports. However, just soaking does not dissolve it well, it really needs some movement. I have seen setups using something like a sonic jewelry cleaner or even a bin of water sitting on a bed slinger printer just moving back and forth for 12 hours.

Hi did you use the BVOH with ABS? what setting did you use for the BVOH?

Any luck on PVA filament? I got a bunch of prints that are in need of supports. I havent used my old printer in like 7 months and Im sure its need calibrated. Got spoiled with X1C LOL… But I want to know if anybody or you had luck with it.

I use eSUN PVA in my AMS all the time. Just make sure to dry it out and that the desiccant in the AMS isn’t saturated. As long as it stays dry it will feed fine.
