![]() ![]() Finally, the mass loss did not vary among the evaluated compositions over a period of 28 days except in the case of β-TCP scaffolds, in which the structural integrity was significantly affected after 28 days of incubation in phosphate-buffered saline. All ceramic bioinks showed consistent printability over a span of 14 days, demonstrating the short-term storability of the formulations. The mechanical properties of the sintered scaffolds were in the range of human trabecular bone for all compositions. Microcomputed tomography and scanning electron microscopy analyses revealed that the structure of the scaffolds, and more specifically, pore size, porosity, and isotropic dimensions were not significantly affected by the sintering process, resulting in scaffolds that closely replicate the original dimensions of the 3D model design. ![]() After sintering at 1200☌, the scaffolds were characterized in terms of structure, mechanical properties, and dissolution in aqueous medium. ![]() The scaffolds were printed using a novel ceramic-based ink with reproducible printability and storability properties. ![]() In this study, we describe the additive manufacturing of porous three-dimensionally (3D) printed ceramic scaffolds prepared with hydroxyapatite (HA), β-tricalcium phosphate (β-TCP), or the combination of both with an extrusion-based process. ![]()
