Processing note
Note: elastic photopolymers may exhibit geometry-dependent mechanical response. Final elasticity, recovery and durability must be validated by the user depending on part design, curing conditions and application environment.
Testing & processing disclaimer
Material performance depends on printer type, thermal control, exposure conditions, geometry and full workflow implementation. Mechanical performance, elasticity, flexibility and final suitability must be validated by the user for each specific application.
