Additive manufactured Triply Periodical Minimal Surface lattice structures with modulated hybrid topology

•Four transition strategies including uniform, linear transition, diagonal transition, and localized diagonal transition were considered in hybrid lattice structures.•A high sensitivity was found between the mechanical performance and the orientation of the contact interface with respect to the loading direction.•Both numerical and experimental data pointed out the criticality of unit cell transition interface design.•The structure with linear transition along width through horizontal waves exhibited the best mechanical properties.
