4Dresyn R-LV1, Rigid Low Viscosity 4D resin

Product description

4Dresyn® R-LV1 is a rigid low viscosity 4D photopolymer designed to exhibit temperature-dependent mechanical behavior, transitioning from rigid below 100 °C to flexible above 120 °C. It is intended to be combined with other 4Dresyn® materials to achieve customized 4D performance and programmed mechanical response.

Application framework

Designed for use in SLA, DLP and LCD vat photopolymerization systems within controlled professional environments. Suitable for multi-material 4D printing applications requiring thermal actuation, shape adaptation or temperature-driven mechanical transitions.

Typical applications

• 4D printing systems requiring temperature-triggered mechanical change
• Multi-material assemblies with programmed stiffness variation
• Shape-morphing or adaptive components
• Thermally responsive structures
• Functional prototypes for smart material systems

Measured mechanical properties
