A novel hybrid Triply Periodic Minimal Surface (TPMS) lattice structure was developed by combining Schwarz-P and Neovius geometries to exploit their complementary advantages. Structures were fabricated from AlSi10Mg using Selective Laser Melting (SLM) under three process parameter regimes corresponding to conduction, transition, and keyhole melting modes. The influence of these parameters on geometry, microstructure, and compressive performance was investigated through quasi-static and dynamic experiments, supported by validated finite element simulations. The results demonstrate a clear process–structure–property relationship. Lattices produced in the transition melting mode (G2) showed the highest hardness, peak load, and specific absorbed energy under both quasi-static and dynamic loading. Relative density and wall thickness were found to be the dominant factors governing lattice-level behavior, while microstructural variations provided secondary contributions. Under increasing impact velocity, all lattices exhibited higher peak and plateau forces and a transition to inertia-dominated deformation, with the strongest velocity dependence observed for G3. The specific absorbed energy increased systematically with velocity despite constant initial kinetic energy, and G2 structures consistently exhibited the highest values across all speeds. These findings establish how SLM process parameters control deformation mechanisms and energy absorption in hybrid TPMS lattices and highlight the transition-mode hybrid architecture as a promising design for impact mitigation and lightweight energy-absorbing components.
