AB  - Laser powder bed fusion (LPBF) is an emerging technique for the fabrication of 
      triply periodic minimal surface (TPMS) structures in metals. In this work, 
      different TPMS structures such as Diamond, Gyroid, Primitive, Neovius, and 
      Fisher-Koch S with graded relative densities are fabricated from 316L steel using 
      LPBF. The graded TPMS samples are subjected to sandblasting to improve the 
      surface finish before mechanical testing. Quasi-static compression tests are 
      performed to study the deformation behavior and energy absorption capacity of 
      TPMS structures. The results reveal superior stiffness and energy absorption 
      capabilities for the graded TPMS samples compared to the uniform TPMS structures. 
      The Fisher-Koch S and Primitive samples show higher strength whereas the 
      Fisher-Koch S and Neovius samples exhibit higher elastic modulus. The Neovius 
      type structure shows the highest energy absorption up to 50% strain among all the 
      TPMS structures. The Gibson-Ashby coefficients are calculated for the TPMS 
      structures, and it is found that the C(2) values are in the range suggested by 
      Gibson and Ashby while C(1) values differ from the proposed range.
