Various types of lattices, including user-defined and natural types, are commonly utilized in additive manufacturing. Some artificial lattices are well-defined mathematically, but a few naturally occurring lattices found in live organisms are still not well understood. Ocean corals are the most prevalent porous lattices accessible. The present study involved the 3D printing of software-generated lattices (gyroid, schwarz, x-cell, cross, square, diamond, and Voronoi) as well as a naturally extracted lattice (coral) using poly lactic acid polymer which also includes an analysis of the density, strength, modulus, and thermal conductivity of the printed lattices. Several artificial lattices were 3D printed with different infill densities, while other lattices, including natural ones, were printed with 100% infill density. The compression test showed that the strength and modulus of the lattice increased as the infill density increased. Similar findings were seen for the thermal conductivity of the lattices. The coral lattice experienced a drop in strength and thermal conductivity as a result of a significant reduction in relative density caused by the presence of non-uniform pore distribution.
