Trabecular Scaffolds’ Mechanical Properties of Bone Reconstruction Using Biomimetic Implants

Abstract Several studies characterized and tested properties related to bone structure like the biomimicry and strength in different printing materials. However, all attempts were unsuccessful in finding the perfect material. Current 3D printing bone technologies can create either hard inert bone structure; that are structurally compatible but functionally inert; or, fragile soft structures that have osteoconductive properties but are extremely weak in structure. The present paper test the designing process of 3D-printed ABS scaffolds using bone's trabecular pattern as an option to enhance the strength of the scaffolds in physiologic load-bearing directions. For this experience, ABS has been considered, as it is widely available in desktop 3D printers. Finally, the mechanical properties of biomimetic scaffolds for compression strength and modulus have been analyzed.
