Filament Spectrum AquaPrint 1.75 mm Natural, 500 g spool

Spectrum AquaPrint 1.75 mm Natural on a 500 g spool is a water-soluble support filament designed for multi-extrusion FDM/FFF 3D printing. Produced for general-purpose prototyping, model making and functional parts where a natural-colour support material is required, this filament offers controlled diameter tolerance and balanced printability for use with dual-extruder setups. The spool has an overall package weight intended for easy handling and storage during printing workflows.

Advantages

AquaPrint provides high flow rate and excellent solubility in cold water compared with traditional PVA support filaments, which reduces dissolving time and simplifies post-processing. The material shows improved adhesion to common build materials such as PLA, PETG, PA and TPU, offering stronger bonding for reliable interlayer contact. Its structural rigidity improves filament feed stability, which is particularly beneficial for Bowden extruder systems and results in consistent support geometry and better final surface finish on printed parts.

Suitable for

• Dual-extrusion prints requiring water-soluble supports
• Complex geometries and overhangs where easy support removal is needed
• Prototyping and model making with mixed-material assemblies
• Functional parts with internal moving components printed in a single build

How to use

Load AquaPrint into the support-extruder of your dual-extrusion 3D printer and the build material into the primary extruder. Set print parameters according to your main material while using the recommended print speed and the filaments diameter tolerance to adjust extrusion multiplier and retraction settings. Use lower printing temperatures where compatible with your nozzle and main material to preserve thermal stability and avoid unnecessary thermal degradation. After printing, remove the bulk of support manually if needed and dissolve remaining support structures in cold water until the model is free of residues.

Usage recommendations

For best results, calibrate extrusion by measuring single-wall test prints and adjust flow rate to account for AquaPrints higher flow characteristics. Ensure good adhesion between support and build material by matching compatible print temperatures and from-bed adhesion settings. Dispose of dissolved support material according to local wastewater regulations and avoid concentrated releases into sensitive environments.
