| Abstract Scope |
Open-porous Ti64 scaffolds are attractive in the field of biomedical implants, since these show reduced stress-shielding and improved osseointegration. Mechanical properties and geometric characteristics of implant scaffolds are tailored to match that of a patient’s bone by using of CAD and FE analysis. Later implants are produced by means of various additive manufacturing routes.
In a previous study, the results of fatigue and quasi-static tests of hot isostatic pressed (HIP) Ti64 scaffold were compared with FE calculations based on the as-designed geometry of a regular cubic cellular scaffold and on the as-built geometry reconstructed from μCT scans.
The current study investigates the fatigued and fractured HIPed Ti64 cubic cellular scaffold (from the previous study) using a 3D correlative multi-scale, multi-modal tomography and microscopy (CMT) framework. The CMT workflow combines advantages of imaging, analytical and metrological capabilities of various instruments and cross-platform correlative holder kit: helical μCT, Plasma_FIB-SEM, Laser_PFIB-SEM and TEM. |
