PVA Filament by purefil – Water-Soluble Support Material for Dual Extrusion Printing

PVA (Polyvinyl Alcohol) is a water-soluble support filament that dissolves completely in cold water, making it an ideal choice for dual extrusion 3D printing. It is particularly effective when used as a support material for complex prints with overhangs, intricate geometries, or enclosed cavities. Once submerged in water, PVA dissolves within 24 hours, leaving behind a clean and smooth printed object without any residue.

Key Benefits of PVA Filament

• Dissolves completely in cold water – No need for chemical solvents.
• Biodegradable – Once dissolved, it can be safely disposed of in regular wastewater.
• Excellent adhesion – Bonds well with popular filaments such as PLA, ABS, and PETG, making it a versatile support material.
• Residue-free removal – Ensures a high-quality finish without post-processing.

Storage & Handling

PVA filament is highly moisture-sensitive and should be stored in sealed, airtight bags when not in use. If the filament absorbs too much moisture, it may lead to bubbling and poor extrusion. To maintain optimal print quality, dry the filament before use if signs of moisture absorption appear.

Why purefil PVA Filament is the Perfect Support Material

purefil’s Swiss-made filaments are known for their high purity, consistency, and printability, ensuring seamless integration with dual extrusion 3D printers. Whether you’re printing detailed prototypes, mechanical components, or artistic models, purefil PVA provides a hassle-free support removal solution.
