PolyDissolve™ S1 (PVA)

Works fine. PETG seems to work better as a PLA support.

I really couldn't be more happy with the filament. I was originally considering soluble filament for supports but I didn't want to deal with dissolving supports all the time while prepping items. I'm running it on a Prusa MK3S+ with an MMU3 with the soluble interface profile on Prusa Slicer and it prints great without any extra tuning. The filament doesn't come off perfectly without some picking at it but the finish is much better than using supports with standard PLA. I'll definitely be using more of this filament in my print farm.

Most importantly it works with PLA +. It also dissolves in hot water from the tap. it did what i needed it to do. I used in in a Bambu Lab X1 carbon through the AMS.

This filament is just as good as Bambulabs support filament for PLA

I should of bought some of this stuff much sooner. Its fantastic for full contact supports. Situations where surface finish and accuracy when using support are critical.However its extremely sensitive to humidity. You really need a dry box, and filament dryer for this stuff. To keep it in good working condition. Even more so if you live in an area with high humidity (like i do). If you do these two things, it should behave extremely well for you. With wonderful results. enclosed chamber is probably also a good idea. I haven't tried too use it on anything that doesn't have a fully enclosed print chamber.So far I have not needed to submerge my parts in water to remove the material. Since its about 80-90% humidity here most of the time. After its out of the print chamber 10-15 minutes in the open air, and I can usually separate and remove this PVA support. With my finger and a small spudger (just to start the separation).I will definitely be purchasing this again.

I just had to post. I see people using this material for the entire support. That's crazy expensive. Just select it for the interface layer of the support. Use the cheaper primary material to generate the bulk of the support. These support filaments last forever if you only use them for the interface between the two materials.
