Fine Tuner 2PP FT9 Bio WS, Bio based & Biocompatible Water Soluble photo accelerant for two photon polymerization

Product description

Fine Tuner 2PP FT9 Bio WS is a bio-based and biocompatible water-soluble photo accelerant additive designed for two-photon polymerization workflows. It is recommended for increasing the cure speed of biocompatible 3Dresyns 2PP resins.

The additive is intended to provide maximum control of writing speed in 2PP printers, with dosage adjustment used to increase writing speed progressively. Overdosage may cause overcure of the resin beyond limits/specifications and result in potential loss of resolution.

Application framework

Designed for incorporation into two-photon polymerization workflows using 2PP printers operating with laser wavelengths in the 600-800 nm range, especially for biocompatible applications and tissue engineering bio scaffolds.

Typical applications

• Increasing cure speed of biocompatible 3Dresyns 2PP resins
• Improving writing speed control in 2PP printers
• Microfabrication of biocompatible structures with high integrity and definition
• Tissue engineering bio scaffolds

Recommended use guidelines

• Recommended for 2PP printers having laser wavelengths in the 600-800 nm range
• Recommended dosage steps: 1-2% in high laser power 2PP printers
• Recommended total dosage: 2-6% on 3Dresyn 2PP without any photo accelerant
• Increase dosage in 1-2% steps starting at 2% dosage
• Normally used at dosages from 2 to 6% by weight
• Avoid over dosage to prevent overcure and potential loss of resolution

Functional performance characteristics

• Water-soluble photo accelerant
• Bio-based and biocompatible
• Ideal for tissue engineering bio scaffolds with extremely low genotoxicity
• Permits the microfabrication of biocompatible structures with high integrity and definition using high laser powers at <200 mW at 800 nm
• Provides a compromise between writing speed and shape accuracy
• Does not exhibit any linear absorption >550 nm
• 100% transparent in the visible range from 550 nm up to 800 nm
• 100% transparent in the near infrared range above 800 nm
• Effective two-photon absorption cross-section at 780 nm permitting 2PP with lasers 780-800 nm with high powers at <200 mW

Processing and handling performance

• Recommended for increasing the cure speed of biocompatible 3Dresyns 2PP resins
• Essential in 2PP printers to have maximum control of writing speed
• Dosage should be increased gradually to optimize writing speed
• Overdosage may lead to overcure and loss of resolution
• Please do not expose any 3D resins to natural or room light to prevent their curing

Physical and handling characteristics

• Water-soluble
• Bio-based
• Biocompatible
• 100% transparent in the visible range from 550 nm up to 800 nm
• 100% transparent in the near infrared range above 800 nm

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 2PP 3D resins from daylight
• 10 g format normally used at dosages from 2 to 6% by weight

Testing & processing disclaimer

Final writing speed, cure behavior and resolution depend on resin formulation, dosage, laser power, wavelength, printing settings and processing 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.
