dc.description.abstractAs 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 biomaterial for engineering structures is less common. This study investigates the development of composite materials for additive manufacturing with casein as a biomaterial filler. To observe the effects of casein on material properties, vat photopolymerization-based and fused filament fabrication-based matrix materials were combined with different weight fractions of casein. Test samples were fabricated to evaluate tensile properties. Test results show a maximum increase of 4% for FFF and 34% for SLA in the stiffness of the materials with casein compared to the neat matrix materials. However, the composite materials showed between 12% and 54% reductions in ductility, and marginal decreases in tensile strengths. The preliminary results indicate viability and prompt further investigation into casein-polymer composites for additive manufacturing.en_US
