Abstract
An additive manufacturing apparatus includes an additive manufacturing print head and a nozzle that receives a bio-based shape memory polymer material and a bio-based material. The nozzle extrudes the bio-based shape memory polymer material and the bio-based material onto a substrate to form a bio-based shape memory polymer part or product.
