3D printing of bio-based soybean oil epoxy acrylate resin

The work deals with the search for bio-based components such as reagents and possible additives already available on the market that could form a bio-based resin suitable for 3D printing. The resins consist of soybean oil epoxidized acrylate as a basic component and it has been carried out the analysis of the printability, finding the best printing parameters for the vat polymerisation technique of all the resins prepared. Finally, the mechanical characterisation of the materials obtained with each formulation was carried out, allowing an analysis of the results and of the compositions.
