Description
Summary:Nowadays the golden standard in orthopedic implants for bone regeneration is the use of allografts and autografts. However, these present problems regarding the availability of the required tissue and risks related to surgery, immune system rejection and pathogen transmission. With the recent development of additive manufacturing, novel porous structures are being looked upon as a possible answer to the afore mentioned problems. In this study, a structure based on the gyroid triply periodic minimal surface was modelled, produced via the fused deposition modeling (FDM) 3D printing method, and mechanically characterized, with the aim of getting one step closer to obtaining bone mimicking implants.
