We describe the fabrication of pliable elastomers derived from functionalized vegetable oil monomers. These bio-based elastomers, derived from plant oils, offer a compelling alternative to petroleum polymers, addressing the increasing demand for flexible, high-strain materials within the realm of 3D-printable soft robotics. Traditional methods for such solutions have been hindered by slow and labor-intensive molding techniques, limiting design flexibility and resolution. In this context, we introduce a photopolymerization 3D-printable system based on easily customizable plant oil acrylates, exhibiting a bio-based carbon content ranging from 62% to 80%. Utilizing stereolithography and light-assisted direct ink writing, the developed bio-based inks enable the printing of diverse structures. This approach facilitates the 3D printing of sustainable, high-resolution structures with specific performance characteristics.
