Filament BambuLab PVA Support for PLA/PETG 1.75 mm 0.5 kg with reusable spool - Clear

BambuLab PVA Support for PLA/PETG 1.75 mm 0.5 kg with reusable spool - Clear is a water-soluble support filament engineered for multi-material 3D printing. Designed to work alongside PLA and PETG, this 1.75 mm PVA comes as 0.5 kg of clear filament wound on a reusable spool. The material dissolves in water, allowing removal of complex internal supports and fine structures without mechanical force, which helps preserve delicate features and reduces manual post-processing time.

Advantages

The filament offers reliable solubility in plain water, enabling clean removal of supports from intricate geometries and internal cavities. Its clear formulation provides good visibility during printing and post-processing, while the reusable spool reduces waste and simplifies storage. Compatibility with PLA and PETG multi-material workflows ensures consistent adhesion to build materials where intended and minimal interaction with the primary print once dissolved.

Suitable for

• Printing complex models with internal channels or trapped cavities
• Multi-material prints using PLA or PETG as the build material
• Prototyping fine-detail parts that require delicate support removal
• Architectural models, figurines, and mechanical assemblies with overhangs

Key specifications

• Filament diameter: 1.75 mm
• Net weight: 0.5 kg of filament
• Material type: Polyvinyl alcohol (water-soluble)
• Colour: Clear (transparent)
• Spool type: Reusable spool suitable for standard 1.75 mm filament holders
• Intended use: Support filament for PLA and PETG multi-material printing

How to use

Load the PVA filament into the support extruder of a compatible multi-material printer and set the primary nozzle(s) to PLA or PETG as required. Use recommended slicer settings for PVA support structures: set appropriate temperatures and retraction parameters according to your printer and materials, and ensure good bridging and interface layers where supports meet the model. After printing, submerge the printed part in water at moderate temperature and allow the PVA to dissolve; gentle agitation or a small pump can speed up dissolution. Rinse and dry the main part after the support has fully dissolved.

Usage recommendations

Store unused filament in a dry, sealed container with desiccant to prevent moisture absorption. Use fresh water at room to warm temperature for dissolution and avoid prolonged exposure of PLA or PETG parts to high-temperature water. When switching back to non-soluble filaments, purge the extruder to prevent moisture-related extrusion issues.
