Abstract Scope |
As the popularity and versatility of additive manufacturing grows, so does interest in developing new materials, including biopolymers. Casein is a protein found in dairy and historically has been used in food applications, but its use as a biopolymer for engineering structures is not common. This study pioneers the investigation into the value of casein in biopolymer composite materials for additive manufacturing. To observe changes to material properties, a base polymer was combined with various weight-percentages of casein. Mechanical testing specimens were produced using both Fused Filament Fabrication and Stereolithography. Test results show increases in the stiffness of the materials with casein compositions over the neat matrix materials. The composite materials had varying reductions in ductility and marginal decreases in tensile strengths. Preliminary results indicates viability and prompts further inquiry into casein-based composites for additive manufacturing. |
