Mechanical properties and microstructure characteristics of lattice-surfaced PEEK cage fabricated by high-temperature laser powder bed fusion
文献摘要：
Porous structure design on the contact surface is crucial to promote the osseointegration of the interver-tebral cage while preventing subsidence and displacement.However,the stress response will undergo sig-nificant changes for the current random porous cages,which can directly affect the mechanical properties and long-term usability.Here,this paper proposed a newly designed polyetheretherketone(PEEK)cage with the triply periodic minimal surface(TPMS)-structured lattice surfaces to provide tailored 3D mi-croporosity and studied the mechanical performance,stress/strain responses,and microstructure changes in depth.The lattice-surfaced PEEK cage mainly exhibits a multiple-point-plane stress transfer mecha-nism.The compression modulus and elastic limit can be adjusted by controlling the area of the Diamond TPMS surface while the energy absorption efficiency remains stable.The microstructure of high-strength PEEK is featured by the radial pattern morphology.Meanwhile,the double-stranded orthorhombic phase is more ordered,and the benzene plane subunit and lattice volume become more expanded.
