Polymaker PolyDissolve S1 PVA Filament 1.75mm - Water Soluble Support

In this review the Polymaker PolyDissolve S1 PVA filament is evaluated as a dedicated water-soluble support material for users who print complex multi-material parts. The bottom line: it is best for makers and small shops that rely on detailed PLA, TPU, PVB, or Nylon prints and need reliable, dissolvable supports. The single biggest reason to buy is its predictable solubility combined with packaging that reduces moisture and tangles, which together make multi-material prints far easier to finish without invasive manual support removal.

Key Features

• Water-soluble support: The filament dissolves in water to free intricate internal cavities and delicate overhangs without mechanical damage to the main print.
• Material compatibility: Formulated for standard-temperature filaments, it works with PLA, TPU, PVB, and Nylon so it fits common dual-extrusion workflows.
• Tangle-free winding: Carefully wound on the spool to reduce the risk of knots and interruptions during long prints.
• Moisture protection: Supplied dried and vacuum-sealed in a resealable bag with desiccant to maintain printability out of the package.
• Updated recycled spool: Packaged on a fully recycled cardboard spool with a reinforced hard edge to prevent fraying and deformation during storage and use.
• Clear printing range: Practical printing settings are provided (nozzle 215C-225C, bed 25C-60C, speed 30-40mm/s) which help reduce tuning time for typical filament pairings.

Who It's For

PolyDissolve S1 is aimed at hobbyists and small professional studios that produce complex geometries such as sculptures, figurines, and parts with internal cavities or moving mechanisms. It is especially useful when the main material is PLA, TPU, PVB, or Nylon and the goal is to avoid sanding or carving support-contact areas.

Those who should look elsewhere include users on a tight budget who do not need dissolvable supports often, since the filament is disposable after use; and users printing only single-material, easily supported geometries where breakaway supports would suffice.

Pros & Cons

Pros

• Reliable water solubility that preserves delicate surfaces and internal features during post-processing.
• Packaged to resist moisture and tangles, which reduces failed prints from filament degradation or snags.
• Compatibility with PLA, TPU, PVB, and Nylon expands dual-extrusion options for many common workflows.
• Recycled cardboard spool with a reinforced hard edge protects filament and helps storage sustainability.

Cons

• Some users report mixed adhesion and print quality results and occasional breakage, so tuning and careful handling are required.
• Perceived value can be an issue since support material is discarded after use, making it a recurring cost for frequent users.

Our Verdict

For anyone doing multi-material or dual-extrusion prints that require clean, non-invasive supports, PolyDissolve S1 is a practical choice because it dissolves reliably and arrives in moisture-controlled, tangle-reduced packaging. It is not the cheapest option, and some prints may need tuning to avoid adhesion or breakage issues, but for detailed work and internal cavities it saves time and preserves surface detail compared with manual support removal.

Frequently Asked Questions

Will this filament work with PLA?
Yes, PolyDissolve S1 is designed to be compatible with PLA and is commonly used as support material in dual-extrusion PLA prints.

How should it be stored?
Keep the filament vacuum-sealed with the desiccant when not in use; after opening store in a dry box or reseal the bag to avoid moisture absorption.

What are the recommended printing temperatures?
The manufacturer suggests a nozzle temperature of 215C-225C and a bed temperature between 25C and 60C with print speeds around 30-40mm/s for 1.75mm filament.
