Fine Tuner FT4 Bio HP, hydrophilic ultra safe bio photo accelerant up to 500 nm

Product description

Fine Tuner FT4 Bio HP is a hydrophilic (non water-soluble), 100% biocompatible photo accelerant additive designed to increase cure speed in high-power SLA, DLP, LCD and Inkjet 3D printing systems.

The formulation provides fast 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.

Fine Tuner FT4 Bio HP is a hydrophilic version of Fine Tuner FT4 Bio with comparable kinetic performance, optimized for biocompatible systems requiring safe, non-cytotoxic behaviour without hazard labels or pictograms.

Application framework

Designed for use in vat photopolymerization systems (SLA, DLP, LCD and Inkjet), particularly in high-power printers (>8 mW/cm²) and biocompatible resin systems requiring safe and efficient cure acceleration.

Typical applications

• Increasing cure speed in biocompatible 3D resin systems
• High-power SLA and DLP printing workflows
• Hydrophilic biocompatible formulations and biomedical applications
• Bioplotting and biofabrication systems
• Low and medium power systems using higher additive loadings

Recommended use guidelines

• Recommended wavelength range: 150–500 nm
• Compatible with UV and visible light systems (LEDs, lasers, DLP projectors, daylight LCDs)
• Optimal for high-power printers (>8 mW/cm²)
• Suggested dosage in high-power systems: 0.5–1 wt%
• Suggested dosage in low-power systems: 1–2 wt%
• High loading option for low-power systems: >4–8 wt%
• Add progressively and mix thoroughly before evaluation
• Avoid overdosing to prevent overcure and loss of dimensional accuracy

Functional performance characteristics

• High cure acceleration across UV and visible spectrum
• 100% biocompatible and non-cytotoxic formulation
• No hazard pictograms or risk phrases

Testing & processing disclaimer

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.

Disclaimer

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.
