Fine Tuner VAM LB4 Bio ULWA, bio-based hydrophobic resolution additive with ultra low water absorption for VAM resins

Product description

Fine Tuner VAM LB4 Bio ULWA is a bio-based hydrophobic resolution additive with ultra low water absorption designed to improve resolution, precision and dimensional accuracy of Volumetric Additive Manufacturing (VAM) resins printed via single and dual color tomographic volumetric printing working with UV and visible lights, such as 460 nm. It is a light purple colored resolution additive developed for applications where high hydrophobicity is required.

It also reduces yellowing while increasing resolution, precision and dimensional accuracy of VAM prints.

Application framework

Designed for incorporation into volumetric additive manufacturing workflows using VAM resins in single and dual color tomographic volumetric printing systems working with UV and visible light sources, especially when improving resolution, precision and dimensional accuracy by reducing overcure beyond specifications.

Typical applications

• Improving resolution of VAM resins
• Improving precision of VAM prints
• Improving dimensional accuracy of VAM prints
• Reducing yellowing of VAM prints
• Reducing overcure in volumetric additive manufacturing workflows
• Applications requiring high hydrophobicity

Recommended use guidelines

• Recommended when lack of resolution is due to overcuring
• Recommended use in increasing steps of 1%
• Use progressively to reduce gradually overcure of the resin beyond specifications
• Optimization is required to obtain optimum resolution, precision and dimensional accuracy in specific VAM printer settings
• If resolution issues are due to undercuring or overcuring, dosage adjustment of the chosen Fine Tuner VAM FT photoaccelerant may also be required depending on the cause
• Can be used in combination with Fine Tuner VAM LB3 Bio ULWA

Functional performance characteristics

• Hydrophobic resolution additive
• Ultra low water absorption: <50 µg/mm3
• Improves resolution, precision and dimensional accuracy
• Reduces yellowing of VAM prints
• Acts to reduce overcure of VAM prints beyond specifications
• Light purple colored additive
• Use in combination with Fine Tuner VAM LB3 Bio ULWA has a resolution synergistic effect

Processing and handling performance

• Essential for increasing print resolution, precision and dimensional accuracy when printing VAM resins with VAM printers
• Fine tuning of VAM resins to the specific printer settings is necessary if the user is not fully satisfied with print resolution, precision and dimensional accuracy
• Calibration STL files are available for confirmation of printability and for determining xyz printing resolution, precision and dimensional accuracy before printing user designs
• Detailed IFU is provided upon request and after ordering for selecting the best printing settings of VAM resins in a specific VAM printer
• The IFU provides a fingerprint of the achievable printing speed, resolution, precision and dimensional accuracy of the chosen VAM 3D resin in the user printer
• The optimum printing settings for the chosen balance of printing speed, resolution, precision and dimensional accuracy are selected by the user following the IFU and basic calibration steps

Physical and handling characteristics

• Bio-based
• Hydrophobic
• Ultra low water absorption: <50 µg/mm3
• Light purple colored
• Can crystallise at low temperature
• Gentle warming and shaking will redissolve the crystals
• Please do not expose any 3D resins to natural or room light to prevent their curing

Packaging and use format

• Supplied as a kit
• Includes the product, one graduated beaker and one empty 100 mL opaque bottle
• Kit is designed to measure, mix, store and protect the 3D resins from daylight

Testing & processing disclaimer

Final resolution, precision and dimensional accuracy depend on resin formulation, dosage, printer settings, overcure behavior and calibration 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.
