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.

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.

• Ultra hard and tough performance for demanding rigid applications
• Clear, isotropic and ultra non-yellowing appearance
• Thermal resistance above 100 °C
• Suitable for HL and VLM manufacturing workflows
• Property tunable with dedicated adjusters

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