Fine Tuner FT5 Bio WS, Water-Soluble Photoaccelerant up to 500 nm

The formulation provides efficient curing kinetics across a broad spectral range (150–500 nm), covering far, medium and near UV as well as visible light sources including LEDs, lasers and DLP projectors.

Designed for use in vat photopolymerization systems (SLA, DLP, LCD and Inkjet), particularly in water-soluble resin systems and biocompatible workflows using medium to high power printers.

• Increasing cure speed in water-soluble 3D resins
• Biocompatible and biofabrication workflows
• Hydrophilic resin systems and biomedical applications
• Bioplotting and soft-material processing

• Recommended wavelength range: 150–500 nm
• Compatible with UV and visible light systems (LEDs, lasers, DLP projectors, daylight LCDs)
• Suggested dosage in high-power systems: 0.5–1 wt%
• Suggested dosage in low-power systems: 1–2 wt%
• Higher dosage (>6–8 wt%) may be required in very low power systems
• Add progressively and mix thoroughly before evaluation

• Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)
• Avoid overdosing to prevent overcure and loss of dimensional accuracy

• Efficient cure acceleration in water-soluble systems
• Full compatibility with hydrophilic and water-soluble resins

• Water-soluble additive
• Natural plant-based composition

• Optimized for medium and high-power SLA and DLP systems
• Limited performance in very low power systems with slow-curing resins
• Compatible with SLA, DLP, LCD, mLCD and Inkjet workflows
• Essential for printers with fixed exposure parameters
• Requires careful dosage adjustment depending on resin reactivity

Fine Tuner FT5 Bio WS is not recommended for very slow-curing resins in very low-power printers, where curing kinetics may remain insufficient even at high dosage levels.

Cure behaviour, print speed and final part performance depend on resin formulation, printer irradiance, wavelength, exposure conditions and post-processing workflow. Optimization must be performed under real printing conditions.

This product is supplied as a formulation additive for professional use in photopolymer engineering and additive manufacturing workflows. It is not a standalone printable material. Final part performance and suitability must be validated by the user according to the intended application.
