Vegetable oil based polymers can be used as materials to prepares TENG and soft actuators. We report several synthesis of rapeseed oil acrylates and epoxides, blend formulations and bioresin processing using light assisted 3D printing methods. DLP and DIW methods were chosen to print demonstrators. The first demonstartors is a pneumatic grip prototype. While the second demostrator is a TENG device of cellular stracture. The synthesized biopolymers showed good performance in both demostrator types. Structure and properties of the biopolymers are discussed. Demonstrators properties is also reported.
