Technical Abstract: Freeform fabrication methods built materials by the repetitive addition of thin layers. This approach can be applied to build parts from mixture of epoxidized soybean oil (ESO) and epoxy resin, which are modified with a gelling agent to solidify the materials until curing occurs. The high strength and stiffness composites are formed through fiber reinforcement. Glass, carbon and mineral fibers are used in the formulations. It is shown that the fiber orientation follows the writing direction and has a large influence on the properties of the composite. In addition, the effects of curing agents, curing temperature, epoxy/ESO ratio and fiber loading on mechanical properties of composites are studied and reported.
