3Dresyn Vitrimer 3R-D70, Reprocessable, Repairable and Recyclable self healing 3D resin for SLA, DLP and LCD printing

Product description

3Dresyn Vitrimer 3R-D70 is a bio-based vitrimer formulation developed for additive manufacturing workflows requiring shape memory, weldability, repairability and sustainable material performance.

This transparent vitrimer system is based on a transesterifiable chemistry without epoxy and is derived from agricultural waste monomers, enabling recyclable and repairable printed parts with thermally activated network rearrangement.

Application framework

Designed for use in SLA, DLP and LCD 3D printing workflows for manufacturing weldable, repairable and shape memory polymer components in controlled professional environments.

Typical applications

• Shape memory printed parts
• Weldable polymer components
• Repairable polymer components
• Sustainable and recyclable vitrimer-based printed parts

Measured mechanical properties

• Tensile strength: <4 MPa, improved 6-7 times after welding
• Flexural strength: <5 MPa(ISO 178)
• Young’s modulus: 10-15 MPa, increased up to 40× after thermal treatment
• Elongation at break: 40%, after repair: ~45-50% of original
• Shore hardness: D60-80, depending on post-curing and thermal treatment
• Storage modulus G′: ≈ 220-230 MPa

Measured thermal properties

• Topology freezing temperature (Tv): 50°C
• Glass transition temperature (Tg): c. 0°C
• Thermal decomposition onset: >310°C (10% weight loss)

Measured physical properties

• Appearance: transparent
• Viscosity: <2000 mPas
• Shrinkage: <15%
• Bio content: 55-60% (ISO 16620)

Functional performance characteristics

• Bio-based vitrimer with shape memory, weldability and repairability

• Transesterifiable system without epoxy
• Sustainable and recyclable

Processing and handling performance

• Weldable and repairable by heating to 180°C for 5 h
• Printable by most commercial and professional SLA, DLP & LCD 3D printers
• Delivery time is around 3-4 weeks after ordering

Chemical and safety characteristics

• Bio based, derived from agricultural waste monomers
• Organo-tin free

Testing & processing disclaimer

Mechanical performance, hardness, repair efficiency, welding response and thermal behavior depend on post-curing conditions, thermal treatment and processing workflow, and must be validated by the user for the intended application.

Disclaimer

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.
