AB  - This paper presented an effective method for the 3D heterogeneous porous scaffold 
      design of human tissue using triply periodic minimal surface (TPMS) internal pore 
      architectures. First, an implicit solid representing the smooth 3D scalar field 
      for the porosity distribution was reconstructed by interpolating the geometric 
      positions of control points and porosity values defined at those points using an 
      implicit interpolation algorithm based on the thin-plate radial basis function. 
      After generating the implicit solid representing the smooth 3D scalar field for 
      the porosity distribution, a functionally graded tissue scaffold with accurately 
      controlled porosity distribution was designed using the TPMS-based unit cell 
      libraries. Numerical results showed that the proposed scaffold design method has 
      the potential benefits for accurately controlling the spatial porosity 
      distribution within an arbitrarily shaped scaffold while keeping the advantage of 
      the TPMS-based unit cell libraries.
