PolymakerPH01001 PolyDissolve™ S1 Filament PVA wasserlöslich 1.75mm 750g Natur 1 pc(s)

TLDR: I recommend getting 2 spools so you can switch them out every 12 hours or so. One printing and one in the drier. As far as dissolving the filament, I just put it in a tub of water for several hours, there were some areas that were still sticking after, I just scrubbed them a bit with a dish brush or tooth brush and they cleaned up well.There is not a lot for me to say that hasn't been said in these reviews already. I just wanted to add that if you're running this in a Bambu AMS system, you will need a filament drier. This filament was superb the first few prints, but then once it absorbed enough moisture to be out of spec, it was terrible. It would keep breaking while being retracted and get jammed in the hot end. Had to completely dismantle the hot end 4 or 5 times. After drying it out, it worked well again.I have read discussions online about people not needing a filament drier because the general atmosphere is dry in a particular region where the person lives. I live in the desert in the Southwest United States where humidity is 20% or less (often 10% or less), and I run a filament drier for all my filaments. You will especially need it for this one. It is designed to absorb water so it will dissolve. It will suck up whatever moisture it comes in contact with.

The only PVA filament I’ve used, so maybe others aren’t any better, but I find it very tricky to print. It doesn’t stick to PLA and it burns and clogs nozzles. I rarely get good results the first time with it. Brilliant in theory, frustrating in practice.I’ve found 200C to be the best printing temperature for it. I dissolve it by putting it in a big mixing bowl full of water. Without agitation, it takes about 24 hours to dissolve; much less if you use warm water and agitate it, but I don’t bother.I’m not very experienced with 3d printing, so your mileage may vary.

I'm not sure what's going on, but the support material often fuses with the PLA. I'm using it on a Bambu X1C with the "Bambu Support W" profile.

This support interface material works the best that I've tried. It works as good as the Bambu product that came with my Bambu printers. Happy with the performance. I think that Polymaker is the official manufacturer for Bambu Labs.

This was my 2nd, and at this price, last shot at trying dissolvable support. I've tried cheap, and now not so cheap PVA and both performed in every possible way absolutely identical. Printer is a snapmaker artisan for what it's worth. Made for dual extrusion/multi material.Does not adhere even to glue on the bed. Tried at all temps. Slowest speeds even. It just goops (even with longer retraction) and then gets knocked off the bed and print ruined. I've concluded that PVA is a waste of money across the board.
