Claim 0:
1. An additive manufacturing method for producing a part or a product, comprising:
providing an additive manufacturing substrate;
positioning an additive manufacturing print head in operative position relative to said additive manufacturing substrate;
providing bio-based shape memory polymer additive manufacturing material in said additive manufacturing print head; and
using an additive manufacturing control system to provide movement of said additive manufacturing print head relative to said additive manufacturing substrate and to extrude said bio-based shape memory polymer additive manufacturing material from said additive manufacturing print head onto said additive manufacturing substrate to form the part or product
wherein said bio-based shape memory polymer additive manufacturing material includes components of shape memory polymer material and bio-based material and
wherein said step of providing bio-based shape memory polymer additive manufacturing material in said additive manufacturing print head comprises the steps of
adding carbon nano fibers fillers to epoxidized soy bean oil and Bisphenol A diglycidyl ether thermoset base resin to from an intermediate material,
adding acetone to said intermediate material,
sonicating said intermediate material,
mixing said intermediate material,
drying said intermediate material, and
degassing said intermediate material.
