Fine Tuner 2PP LB3 Bio ULWA, biocompatible and bio-based hydrophobic resolution-er with ultra low water absorption for improving resolution of two photon polymerization 2PP resins

Product description

Fine Tuner 2PP LB3 Bio ULWA is a biocompatible and bio-based hydrophobic resolution additive designed to improve resolution, precision and dimensional accuracy of two-photon polymerization resins. It is a clear resolution additive developed to improve xyz resolution, precision and dimensional accuracy by reducing overcure of 2PP prints beyond specifications.

The formulation is a polymerization retarder recommended for increasing resolution by reducing printing speed and undesired overcure of two-photon polymerization prints, including biomedical applications where high hydrophobicity, safety and biocompatibility standards are required.

Fine Tuner 2PP LB3 Bio ULWA is described as a 100% safe hydrophobic biocompatible resolution additive with ultra low water absorption and with a Material Safety Data Sheet free of toxic hazards and pictograms.

Application framework

Designed for incorporation into two-photon polymerization workflows using 2PP printers, especially when improving resolution, precision and dimensional accuracy by reducing overcure of the resin beyond specifications.

Typical applications

• Improving xyz resolution of 2PP resins
• Improving precision of 2PP prints
• Improving dimensional accuracy of 2PP prints
• Reducing overcure in two-photon polymerization workflows
• Biomedical applications requiring high hydrophobicity, safety and biocompatibility

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 2PP printer settings
• If resolution issues are due to undercuring or overcuring, dosage adjustment of Fine Tuner 2PP FT8 Bio may also be required depending on the cause

Functional performance characteristics

• Hydrophobic resolution additive
• Ultra low water absorption: <50 µg/mm3
• Improves resolution, precision and dimensional accuracy
• Reduces overcure of 2PP prints beyond specifications
• Acts as a polymerization retarder
• Reduces printing speed to improve resolution
• Clear additive
• Suitable for applications requiring the highest hydrophobicity, safety and biocompatibility standards

Processing and handling performance

• Essential for increasing print resolution, precision and dimensional accuracy when printing 2PP resins with 2PP printers
• Fine tuning of 2PP 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 2PP resins in a specific 2PP printer
• The IFU provides a fingerprint of the achievable printing speed, resolution, precision and dimensional accuracy of the chosen 2PP 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

• Biocompatible and bio-based
• Hydrophobic
• Ultra low water absorption: <50 µg/mm3
• 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 two-photon polymerization 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.
