PolyDissolve™ S1: Water-Soluble Support for Complex 3D Prints

PVA-Based, Water Dissolvable Support
PolyDissolve™ S1 is a PVA-based filament engineered to provide water-soluble support for PLA, TPU, PVB, and Nylon-based filaments. It forms a perfect interface with these materials, offering strong support during printing and dissolving cleanly in water for easy post-processing.

Optimized Compatibility and Solubility
Specifically designed for use with Polymaker’s PLA, TPU, PVB, and Nylon filaments, PolyDissolve™ S1 displays excellent solubility and is ideal for intricate prints with complex overhangs and internal structures.

Dissolving and Post-Processing
Supports typically dissolve in 6–12 hours. Dissolution can be sped up by increasing water temperature, changing water regularly, or adding water movement.
Ideal for Multi-Material and Complex Prints

Choose PolyDissolve™ S1 when you need reliable, easily removed water-soluble supports for detailed, multi-material 3D printing projects.

Printing Requirements
  • Filament dryer - PolyDissolve is very hygroscopic.
  • Highly recommended to use a printer with two nozzles - such as an IDEX or Tool Changer. You will have issues with clogging when printing two material types out of a single nozzle.

Other than that - no requirements! No enclosure, high temp hotend, or hardened nozzle required.

Product Information & Downloads

Customers praised this PVA support filament for excellent surface finish and full contact support capabilities. It works well with PLA and dissolves in hot water. Reviewers noted it's "fantastic" for interface layers and comparable to premium brands. However, the material is extremely sensitive to humidity, requiring dry boxes and filament dryers for optimal performance.

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

Happy with the filament quality

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.

Works well, dissolves in hot water

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.

Just as good as Bambulabs

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

Fantastic for full contact supports

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.

Great filament for support interface layer

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.

can you use the polydissolve s1 pva filament for support on a PET GF15 part

Polymaker

No - we suggest the recommended support material: Polysupport for PA12
