The merger of additive manufacturing (AM) and biomaterials have great implications in tissue engineering as it allows for the customization of medical instruments, prosthetics, and in vitro models. Polymeric composite materials used in bone tissue engineering present a challenge as particles (typically at high volume percentages) are used as fillers. Great advances have been achieved in the fabrication of biomaterials for bone tissue engineering using 3D printing. Such advanced platforms include sintered biomaterials that are based from hydroxyapatite and tricalcium phosphate, inorganic bone substitutes that resemble the mineral content of bone. However, such materials lack the organic collagen and other bone derived proteins that are critical in cell-bone matrix interactions. In this study, the dispersion of allograft bone particles in reactive polyurethane is studied to enhance its utility in AM.
