3Dresyn UHV-UTFD80 Bio, Biocompatible Ultra Tough & Foldable resin with Shore D80 for Hot Lithograghy HL and Viscous Lithography Manufacturing VLM

Product description

3Dresyn® UHV-UTFD80 Bio is a non-yellowing ultra tough and foldable monomer-free photopolymer developed for Hot Lithography (HL) and Viscous Lithography Manufacturing (VLM) applications requiring high flexibility, foldability without breaking, impact resistance and biocompatible-grade safe handling.

Application framework

Designed for use in Hot Lithography (HL) and Viscous Lithography Manufacturing (VLM) systems within controlled professional environments. Suitable for the fabrication of durable foldable parts, impact-resistant flexible components and technical applications requiring toughness, resilience and very low shrinkage.

Typical applications

• Foldable technical parts requiring repeated deformation without breaking
• Impact-resistant flexible components for HL and VLM workflows
• Durable parts requiring high shattering resistance
• Flexible structural elements with controlled hardness
• Applications requiring tunable rigidity while maintaining foldability

Processing note

Note: foldable and highly tough photopolymers may show application-dependent behavior depending on wall thickness, print orientation, cure state, thermal history and long-term deformation conditions. Final flexibility, foldability and durability must be validated by the user under the intended workflow and service conditions.

Testing & processing disclaimer

Material performance depends on printer type, thermal control, exposure conditions, geometry and full workflow implementation. Mechanical performance, foldability, impact resistance and final suitability must be validated by the user for each specific application.
