Filament Gembird PVA [1,75mm, 1kg]

GEMBIRD PVA 1.75 mm water-soluble filament – the ideal support material for 3D printing

GEMBIRD PVA (polyvinyl alcohol) is a high-quality water-soluble filament designed as a support material for printing complex 3D models. It allows you to print overhangs, cavities, and detailed structures that would be impossible to create with conventional materials. After printing, the supports can be easily dissolved in water, giving you a clean, accurate, and professional result without the need for mechanical removal of the supports.

🧩 Main advantages of GEMBIRD PVA filament

Water-soluble material – simply remove the support by immersing it in water

Clean model surface – leaves no marks or damage to the main print

Soluble at normal temperature, the process can be accelerated with warm water (40–50 °C)

Eco-friendly solution – PVA is biodegradable and environmentally friendly

⚙️ Compatibility

Perfect for dual-extruder 3D printers

Excellent adhesion to PLA, PETG, and other filaments

Ideal for printing complex prototypes, architectural models, and mechanical parts with cavities

💡 Practical tips for printing with PVA

Make sure the filament is completely dry before printing

Store it in an airtight container with a moisture absorber

Use a closed print chamber for better results

After printing, immerse the model in water at 40–50 °C to dissolve the supports faster

You can speed up the dissolution by gently moving the water or replacing it

📦 Storage and maintenance

PVA is a highly hygroscopic material—it easily absorbs moisture.

Store it in a dry place, away from direct sunlight and moisture.

We recommend using a filament dryer (e.g., PolyDryer).

If it gets wet, dry it at 40–45 °C for 4–6 hours.

🌱 Environmental aspect

GEMBIRD PVA filament is fully biodegradable and completely dissolves in water.

The solution is environmentally friendly and can be disposed of in the usual way via the sewage system.

When disposing of larger quantities, follow local waste disposal regulations.
