3.0mm PVA PVA Water-Soluble Filament (0.5kg)

A 0.5 kg spool of 3.0 mm PVA (polyvinyl alcohol) filament for use as water-soluble support material in dual-extruder 3D printers. Print complex overhangs and bridging structures with PVA supports, then simply dissolve them in water for a clean finish — no cutting or sanding required.

Key Features

• Water-Soluble – Dissolves in water for easy support removal
• Biodegradable – Environmentally friendly support material
• 3.0 mm Diameter – ±0.05 mm tolerance for consistent extrusion
• Low Melting Point – 160 °C melting temperature, 210–215 °C nozzle temperature

Specifications

• Colour – Pale yellow
• Diameter – 3.00 mm ±0.05 mm
• Net Weight – 0.5 kg (1.1 lbs)
• Melting Temperature – 160 °C
• Nozzle Temperature – 210–215 °C
• Density – 1.3 g/cm³ (at 21.5 °C)
• Spool Size – 170 × 170 × 55 mm
• Spool Hub Hole – 50 mm

Usage Tips

• Storage – PVA absorbs moisture; process only from the unopened original bag. Damp filament can be dried at 60–80 °C for 6–8 hours in a circulated air dryer
• Temperature – Do not exceed 175 °C as higher temperatures cause thermal damage. Keep residence time under 5–10 minutes
• Dissolving – Submerge printed parts in room-temperature water. A 10 cm cube at 20% infill will begin breaking apart within 20 minutes and dissolve entirely within 24 hours. Warm water and gentle stirring speed up the process

Ideal For

• Dual-extruder 3D printers requiring soluble supports
• Complex prints with overhangs, bridges, and internal cavities
• Prototyping parts that need smooth, support-free surfaces
