AB  - Additive Manufacturing (AM) is rapidly evolving due to its unlimited design 
      freedom to fabricate complex and intricate light-weight geometries with the use 
      of lattice structure that have potential applications including construction, 
      aerospace and biomedical applications, where mechanical properties are the prime 
      focus. Buckling instability in lattice structures is one of the main failure 
      mechanisms that can lead to major failure in structural applications that are 
      subjected to compressive loads, but it has yet to be fully explored. This study 
      aims to investigate the effect of surface-based lattice structure topologies and 
      structured column height on the critical buckling load of lattice structured 
      columns. Four different triply periodic minimal surface (TPMS) lattice topologies 
      were selected and three design configurations (unit cells in x, y, z axis), i.e., 
      2 x 2 x 4, 2 x 2 x 8 and 2 x 2 x 16 column, for each structure were designed 
      followed by printing using HP MultiJet fusion. Uni-axial compression testing was 
      performed to study the variation in critical buckling load due to change in unit 
      cell topology and column height. The results revealed that the structured column 
      possessing Diamond structures shows the highest critical buckling load followed 
      by Neovius and Gyroid structures, whereas the Schwarz-P unit cell showed least 
      resistance to buckling among the unit cells analyzed in this study. In addition 
      to that, the Diamond design showed a uniform decrease in critical buckling load 
      with a column height maximum of 5193 N, which makes it better for applications in 
      which the column's height is relatively higher while the Schwarz-P design showed 
      advantages for low height column maximum of 2271 N. Overall, the variations of 
      unit cell morphologies greatly affect the critical buckling load and permits the 
      researchers to select different lattice structures for various applications as 
      per load/stiffness requirement with different height and dimensions. Experimental 
      results were validated by finite element analysis (FEA), which showed same 
      patterns of buckling while the numerical values of critical buckling load show 
      the variation to be up to 10%.
