Solid freeform fabrication of epoxidized soybean oil/epoxy
Extrusion freeform fabrication has been used to make bars of fiber-reinforced epoxidized soybean oil (ESO)/epoxy resin. Freeform fabrication methods build materials by the repetitive addition of thin layers. The mixture of epoxidized soybean oil (ESO) and epoxy resin are modified with a gelling agent to solidify the materials until curing occurs.

Chemical Solid Free-Form Fabrication: Making Shapes
Solid free-form fabrication methods are surveyed. This approach of making objects by depositing material layer by layer lends itself to the direct conversion of fluid reactants to a solid part, as opposed to the production of a material and its subsequent processing. Examples are given of the formation of ceramics, metals, thermoplastics, thermosets, and composites.
