3Dresyn UHV-UHTD90 Bio, Biocompatible ultra hard & tough resin with Shore D90 for Hot Lithograghy HL and Viscous Lithography Manufacturing VLM

Product description

3Dresyn® UHV-UHTD90 Bio is a clear, non-yellowing ultra hard and tough photopolymer developed for Hot Lithography (HL) and Viscous Lithography Manufacturing (VLM) applications requiring high impact resistance, high rigidity, elevated thermal 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 rigid parts, clear technical components, ophthalmic-related prototyping applications and molds requiring high toughness, dimensional stability and resistance to shattering.

Typical applications

• Durable molds for injection temperatures up to 100 °C
• Ultra-rigid and tough technical parts for HL and VLM workflows
• Clear non-yellowing components requiring optical stability
• Impact-resistant rigid parts with high hardness
• Ophthalmic lens-related prototyping and clear isotropic parts

Processing note

Note: high hardness and high HDT photopolymers may still require application-specific validation depending on geometry, impact conditions, thermal exposure and long-term service environment. Optical performance for lens-related applications must be validated by the user under the intended manufacturing and post-processing conditions.

Testing & processing disclaimer

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