Proceedings of the Institution of Mechanical Engineers Part E Journal of Process Mechanical Engineering, Год журнала: 2025, Номер unknown

Опубликована: Март 17, 2025

This study investigates the impact of six distinct lattice structures (Gyroid, Diamond, Schwarz, SplitP, Lidinoid, and Kelvin) on mechanical performance biocompatibility CoCrMoW-based tibial implants. Finite element analysis was conducted using nTopology to simulate compression tests under a 3100 N load, evaluating important parameters such as stress, strain, displacement, reaction forces, mass, volume, porosity. Global stiffness values were calculated based test results. The effect structure designs global properties determined. results show that improve strength implants reduce mass value, consequently improving osseointegration long-term stability.

The aim of this work is to analyze the effect heating rate used during debinding step on consolidation parts fabricated by additive manufacturing using 3D printing extrusion Ti64 samples. cylindrical samples print extruding MIM pellets mixed with a binder. Dilatometry tests follow densification three different rates stage. All then undergo same thermal cycle sintering. SEM and XRD microstructure. Microhardness compression evaluate mechanical properties sintered We corrosion behavior under Hank’s solution. results indicated that affects reducing as increases. After sintering, lower relative density reached, resulting in decreased resistance. Young’s modulus yield strength correspond well those prepared other techniques similar porosities. Despite remaining porosity, SLM had worse than ours. main conclusion isothermal not necessary ensure complete binder elimination, which will reduce process time thus, fabrication costs technique.
