Simplify3d has several options for infill pattern. I was curious which option offered the best compressive strength. ASTM D695 lays out some guide lines for testing the compressive strength of plastics. The test specimen is 1/2" x 1/2" x 1". I printed two of each of the following infill patterns: rectilinear, grid, triangular, wiggle, fast honeycomb, full honeycomb. All at 10% infill density. Pri
