• Compatible with Hot Lithography and Viscous Lithography Manufacturing systems
• Hardness and rigidity can be increased with 3Dresyn HA1 HV MF Bio at user-selected dosages typically in the range of 1–15% by weight, subject to validation
• Broader property adjustment can be achieved with 3Dresyn SA1 HV Bio and 3Dresyn HA1 HV MF Bio
• More detailed property adjustment without sacrificing foldability can be achieved with 3Dresyn SA2 LV Bio and 3Dresyn HA2 LV Bio

Note: highly flexible and foldable photopolymers may exhibit geometry-dependent mechanical behavior. Final flexibility, softness, foldability and durability depend on part thickness, curing conditions and thermal history and 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, foldability, softness and final suitability must be validated by the user for each specific application.

• Ultra tough and highly foldable performance for flexible applications
• Lower hardness (D70) for softer and more compliant parts
• Non-yellowing appearance and very low shrinkage
• Suitable for HL and VLM manufacturing workflows
• 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, foldability and process validation remain the responsibility of the user depending on printer, part design, thermal exposure and workflow conditions.
