Fine Tuner VAM FT4 Bio, hydrophobic ultra safe bio photo accelerant up to 500 nm for VAM resins

Product description

Fine Tuner VAM FT4 Bio is a hydrophobic version of Fine Tuner VAM FT4 Bio HP with similar kinetics performance. It is a 100% biocompatible accelerant 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.

The additive is described as 100% safe and biocompatible, without toxic phrases or pictograms. It is also indicated for increasing the print speed of hydrophobic biocompatible VAM resin systems.

Application framework

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 biocompatible VAM resin systems.

Typical applications

• Increasing cure speed of VAM resins
• Increasing print speed of hydrophobic biocompatible VAM resin systems
• Fine tuning VAM printing workflows in high power and low power printers
• Biocompatible volumetric additive manufacturing applications

Recommended use guidelines

• 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
• Increase dosage gradually to increase printing speed
• Avoid over dosage to prevent overcure and potential loss of resolution, precision and dimensional accuracy
• Resolution and dimensional accuracy can be increased with Fine Tuner VAM LB3 Bio ULWA

Packaging and use format

• Supplied as a kit
• Includes the product, one graduated beaker and one empty 250 mL black bottle
• Kit is designed to measure, mix, store and protect the 3D resins from daylight

Testing & processing disclaimer

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.

Disclaimer

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.
