Experiment 1 : Grid vs Honeycomb vs Gyroid
In usual cases, “Linear”, “Grid” and “Honeycomb” are optional infill patterns for 3D Printing. Compared to them, we believe “Gyroid” has better performance as an infill pattern for some cases. So we conducted physical experiments. Through compression analysis, we found Gyroid is strong enough both to horizontal and vertical pressures, while grid and honeycomb are not enough to horizontal pressures.
Maximum compression load value (Vertical to the stacking direction)
Grid ---> 2,196 [N]
Honeycomb ---> 2,623 [N] (overload)
Gyroid ---> 2,770 [N] (overload)
Maximum compression load value (Horizontal to the stacking direction)
Grid ---> 1,374 [N]
Honeycomb ---> 2,005 [N]
Gyroid ---> 2,533 [N] (overload)
Experiment 2 : Octet truss vs Gyroid
Octet Truss, proposed by famous Richard Buckminster Fuller, is another candidate as better infill pattern for 3D Printing. We conducted compression analysis to compare Gyroid to octet truss. As a result, Gyroid shows 1.48 times better in performance.
Maximum compressive load value
Octet truss ---> 13.66 [kN]
Gyroid ---> 20.22 [kN]
Maximum displacement value
Octet truss ---> 5,688 [mm]
Gyroid ---> 9.901 [mm]
