AB  - This study aims to design and manufacture different lattices and evaluate their success in terms of compression strength. Structures with a high surface area to volume (SA:V) ratio and microporosity are designed to mimic cancellous bone tissue. The volume-centered cubic and face-centered cubic lattice structures are higher in terms of the SA:V ratio among the designed specimens. Specimens in the cylindrical form used with four different lattices were successfully produced by 3D (Digital Light Processing) DLP printing. A preliminary evaluation of the lattices was made by searching for the lowest stress and displacement values under compression load with finite element analysis. The lowest von-Mises stress value was 6.37 MPa in the simple cubic lattice structure. The compression test was carried out under quasi-static conditions with equal preloading. The loads at onset damage were compared. The highest fracture average load was in face-centered cubic lattice structures with 10.14 kN. Among the specimens with low standard deviation in the compression test, the simple cubic and gyroid lattice structures’ fracture force is higher.
