Note: ultra-soft elastic photopolymers may exhibit strong dependence on geometry, curing conditions and loading conditions. Final elasticity, elongation and durability must be validated by the user for the intended application.

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

• Ultra-soft elastic performance with very high elongation
• Shore A20 for highly compliant applications (ISO 868)
• Rubber-like behavior with high deformation capability
• Non-yellowing appearance and very low shrinkage
• Suitable for HL and VLM manufacturing 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, elasticity 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.
