Abstract: The lightweight design heavily relies on thin-walled porous structures, and laser additive manufacturing has great advantages in the manufacture of complex thin-walled structures. To enhance the in-plane load-bearing properties of porous structures, the innovative concept of introducing additional supporting structures was applied to the hexagonal honeycomb(HH) structure. Through structural optimization and utilizing selective laser melting technology, two new structures, namely edge-enhanced honeycomb(BEEH) and plane-enhanced honeycomb(BPEH), were fabricated. The results show that under the same porosity conditions, both BEEH and BPEH exhibit higher elastic modulus and yield strength compared with the HH structure, with increase of 121.83%, 76.75% and 163.20%, 102.30% respectively. During compressive deformation, the stress distribution differs among the structures, and for the HH structure, it concentrates at the edge intersections, while BEEH and BPEH show uniform stress distribution. The HH structure demonstrates an "X" type deformation failure mode, whereas BEEH and BPEH structures exhibit an "I" type deformation failure mode. These research findings are expected to offer theoretical guidance and technical support for the design of energy absorption devices and the realization of lightweight technologies.
