3Dresyn UHV-HFA90 Bio, Biocompatible hard and flexible resin with Shore A90 for Hot Lithograghy HL and Viscous Lithography Manufacturing VLM

Designed for use in Hot Lithography (HL) and Viscous Lithography Manufacturing (VLM) systems, as well as selected room temperature processes, within controlled professional environments. Suitable for the fabrication of durable flexible parts with high hardness, impact resistance and dimensional stability, particularly in thicker geometries.

Note: hard-flexible photopolymers may exhibit geometry-dependent behavior, particularly in thick sections where stress distribution differs from thin parts. Final mechanical performance, flexibility and durability must be validated by the user under real application and processing conditions.

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

• Hard and flexible performance without brittle failure
• Rubber-like behavior with Shore A90 hardness (ISO 868)
• High impact and shattering resistance, especially in thick sections
• Non-yellowing appearance and very low shrinkage
• Compatible with HL, VLM and room temperature workflows
• Very high resolution and durability
• Rigidity tunable with dedicated adjusters

This material is supplied as a professional manufacturing material and is not marketed as a finished product. Final performance, durability, flexibility and process validation remain the responsibility of the user depending on printer, part design, thermal exposure and workflow conditions.

This technical datasheet should be used together with the relevant processing, calibration, safety and workflow documentation available in the 3Dresyns® Resources section.
