4Dresyn TF-LV1, Tough & Foldable Low Viscosity 4D resin

4Dresyn® TF-LV1 is a tough and foldable low viscosity 4D photopolymer designed to exhibit temperature-dependent mechanical behavior, transitioning from rigid below 10 °C to tough and flexible above 20 °C. It is intended to be combined with other 4Dresyn® materials to achieve customized 4D performance and programmed mechanical response.

Designed for use in SLA, DLP and LCD vat photopolymerization systems within controlled professional environments. Suitable for multi-material 4D printing applications requiring temperature-triggered flexibility, shape adaptation or responsive mechanical behavior.
