Processing note

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.

Testing & processing disclaimer

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.
