Polymaker PolyDissolve S1 is a water-soluble PVA-based support filament designed for printing complex models with overhangs and internal cavities. Once printing is complete, the supports simply dissolve in lukewarm water without leaving any traces on the surface of the main model.

Key features

PolyDissolve S1 is a specialized support material compatible with most common printing materials, including PLA, PETG, nylon and TPU. The filament fully dissolves in water at room temperature, eliminating the need for mechanical support removal and the risk of damaging the model. The material is suitable for dual-extrusion 3D printers and IDEX systems. The 1.75 mm filament diameter ensures compatibility with the vast majority of FDM/FFF printers on the market.

Printing parameters

Who is Polymaker PolyDissolve S1 PVA, 1.75mm, 750g suitable for

PolyDissolve S1 will be appreciated by users who print complex geometries with overhangs, internal cavities or moving parts that cannot be printed with conventional break-away supports. It is ideal for prototyping mechanical parts, functional assemblies, anatomical models, artistic objects and any prints where high-quality bottom surfaces are required. The material is intended for dual-extruder printers, where it serves as a support filament for the main printing material.

Printing tips

• PVA is highly hygroscopic - always thoroughly dry the material before printing (70 °C, 6-8 hours) and ideally use a filament dryer during printing.
• Store unused spools in an airtight container with silica gel.
• Set the nozzle temperature as close as possible to that of the main material you are combining PVA with.
• Avoid prolonged heating in the nozzle without printing - PVA decomposes at higher temperatures and may cause clogging.
• After printing, immerse the model in lukewarm water (30-40 °C); dissolution can be accelerated by gentle water flow or an ultrasonic bath.
• Do not pour water with dissolved PVA directly down the drain in large quantities - let it evaporate or dispose of it according to local regulations.
• For better adhesion between PVA and the main material, use interface layers in your slicer software.
