FlashForge PB2 PVA wateroplosbaar supportfilament 1,75 mm 500 g naturel

When printing complex models with overhangs or intricate internal cavities, standard supports can be a nightmare to remove. The FlashForge PB2 PVA filament solves that: print your supports with this water-soluble material, then simply dissolve them away in tap water, leaving a clean, smooth surface on your main print. Ideal for dual-extruder 3D printers, PB2 is a must-have for advanced makers, engineers, and prototyping labs.

Key specifications

• Material: PVA (Polyvinyl Alcohol) – water-soluble support material
• Diameter: 1.75 mm with tight tolerance of ±0.02 mm
• Net weight: 500 g spool
• Colour: Natural / translucent
• Printing temperature: 180–200 °C
• Heated bed temperature: 40–60 °C
• Recommended print speed: 20–40 mm/s
• Density: 1.23 g/cm³
• Compatible with standard brass nozzles (0.4 mm or larger)
• Low odour and biodegradable

Why choose it

PB2 eliminates the frustration of support removal. Unlike breakaway supports that can damage delicate features or leave marks, PVA dissolves completely, enabling designs that were previously impossible to print. Its consistent diameter and low moisture absorption (when stored properly) ensure reliable feeding and excellent layer adhesion. The natural translucent colour blends discreetly and does not affect the appearance of your main material.

Ideal use cases

• Complex architectural models with intricate details
• Mechanical parts with internal channels or cavities
• Prototypes requiring smooth, support-free surfaces
• Multi-material prints with dissolvable support interfaces
• Educational projects demonstrating advanced 3D printing techniques

Good to know

PVA is highly hygroscopic; always store the spool in a sealed container with desiccant when not in use. For best results, use a dual-extruder printer with a dedicated nozzle for PVA. Dissolve supports in warm water (not hot) to speed up the process without warping your main print. After dissolution, rinse the part thoroughly and allow it to dry completely.
