AB  - Metallic lattice structures can be fabricated by selective laser melting (SLM) 
      with purposefully designed pores and controlled pore sizes that can bio mimic the 
      natural bone, providing adequate mechanical and biological support for the 
      patients. Strut-based structures, like Cubic, Octet; and sheet-based structures, 
      like triply periodic minimal surface (TPMS) gyroid, have been studied extensively 
      in the past. However, it lacks enough comparative study on the mechanical 
      properties and cytotoxicity among these structures. Therefore, Cubic, Octet, and 
      TPMS gyroid of Stainless steel 316 L (SS316L) are designed, manufactured, and 
      characterized at 40/50/60% relative densities in this study. Moreover, the 
      flowability, density characteristics, and cytotoxicity of SS316L powder are 
      validated to ascertain its suitability for 3D printing and implant application. 
      Based on refining the Gibson-Ashby model, it is possible to predict or design the 
      mechanical properties via adjusting the relative densities. The results indicate 
      these structures demonstrated appropriate Young's modulus and outstanding 
      biocompatibility.
