Fine Tuner VAM FT4 Bio, Hydrophobic Photoaccelerant for VAM

Fine Tuner VAM FT4 Bio is a hydrophobic version of Fine Tuner VAM FT4 Bio HP with similar kinetics performance. It is a bio-based photoaccelerant additive designed to increase the cure speed of Volumetric Additive Manufacturing (VAM) resins printed via tomographic volumetric printing, working with UV and visible light wavelengths from 150 to 500 nm.

It is also indicated for increasing the print speed of hydrophobic VAM resin systems.

Designed for incorporation into volumetric additive manufacturing workflows using tomographic volumetric printing systems operating with UV and visible light sources from 150 to 500 nm, especially for hydrophobic VAM resin systems.

• Density: 0.90–1.20 g/cm³, depending on formulation and, where applicable, selected version (ISO 1675)
• Resolution and dimensional accuracy can be increased with Fine Tuner VAM LB3 Bio ULWA
• Viscosity: optimized within the processing range required for the intended printing process and application
• Ultra low water absorption
• Avoid over dosage to prevent overcure and potential loss of resolution, precision and dimensional accuracy
• Overdosage may lead to loss of resolution, precision and dimensional accuracy

• Bio-based formulation

• Fine tuning VAM printing workflows in high power and low power printers
• Recommended wavelength range: 150-500 nm
• Suggested dosage in high power VAM printers: <0.5-1 wt% incremental steps
• Suggested dosage in low power VAM printers: <1-2 wt% incremental steps
• Compatible with tomographic volumetric printing workflows
• Suitable for high power and low power VAM printers
• Please do not expose any 3D resins to natural or room light to prevent their curing

Final cure speed, printing speed, resolution, precision and dimensional accuracy depend on resin formulation, dosage, printer irradiance, wavelength, exposure conditions and processing workflow. Optimization must be performed under actual printing conditions.

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