Filament Fiberlogy BVOH 1.75 mm 0.5 kg – water-soluble support material

Fiberlogy BVOH filament, 1.75 mm diameter on a 0.5 kg spool, is a water‑soluble support material designed for FFF/FDM 3D printing. It dissolves in water to allow complete removal of support structures from complex prints, enabling clean surfaces in cavities, internal channels and assemblies that require temporary supports. The filament is intended to be used alongside standard build materials where detachable or inaccessible supports would otherwise be difficult to remove.

Advantages

BVOH offers reliable water solubility that ensures supports can be removed without mechanical force, reducing the risk of damaging delicate features. Its compatibility with common printing temperatures for many thermoplastics allows it to be printed as a separate support extruder material. The filament improves final part quality by minimizing post‑processing and by producing consistent, low‑residue dissolution when immersed in water.

Suitable for

• Printing multi‑material parts with complex overhangs and internal cavities
• Prototyping assemblies with interlocking or moving parts that require temporary supports
• Creating models with internal channels for fluid or airflow testing
• Manufacturing parts where manual removal of supports is impractical or would damage surfaces

Key specifications

• Diameter: 1.75 mm nominal
• Spool weight: 0.5 kg of filament
• Material type: water‑soluble BVOH (butenediol vinyl alcohol copolymer)
• Intended use: support material for FFF/FDM 3D printers with dual‑extrusion or soluble support setups
• Solubility: water‑soluble at ambient or elevated temperatures depending on part geometry

How to use

Load Fiberlogy BVOH into a dedicated support extruder or set it as the support material in your slicer. Configure printing temperatures and retraction settings according to your printer and the build material manufacturer recommendations; typical setups print BVOH at temperatures compatible with common thermoplastics used for the main model. Print the model using dual‑extrusion or similar workflows so the main material and BVOH are deposited separately. After printing, immerse the part in water to dissolve the BVOH supports; agitation or gentle warm water can accelerate dissolution for intricate structures. Dry the part thoroughly after support removal before any further finishing or assembly.

Usage recommendations

Store the spool in a dry, low‑humidity environment and keep it sealed with desiccant when not in use, as BVOH is hygroscopic. For best results, test a small sample print to fine‑tune temperature, flow and support interface settings for compatibility with your main printing material.
