However, the manufacture of soft robotic devices and machines still largely relies on petroleum\u2010based polymers. Furthermore, in light\u2010induced 3D printing, a key technology for fabricating complex 3D monolithic soft robots, non\u2010sustainable resins remain predominant. This work addresses this issue by developing a photocurable bio\u2010based resin to monolithically fabricate soft robots. We formulate a resin using soybean oil as a renewable precursor and shape it via Digital Light Processing into an origami\u2010inspired vacuum\u2010actuated actuator. The bio\u2010based material has a Young's modulus of 18.9\u00a0MPa and an elongation at break of 19.6%. The origami deformation, based on folding rather than stretching, enables actuator operation, despite the lower elongation range of our material compared to silicone elastomers. We report on the characterization of the bulk material properties and the mechanical performance of the actuator, which performs 2000 cycles without failure before testing ceased. Finally, we design and fabricate a monolithic soft robotic gripper with integrated origami actuation using our bio\u2010based material. We show the functional operation of the gripper in grasping different objects, as well as in underwater settings.<\/jats:p>","DOI":"10.1002\/advs.202520529","type":"journal-article","created":{"date-parts":[[2026,1,22]],"date-time":"2026-01-22T06:34:01Z","timestamp":1769063641000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Monolithic
