Desktop 3D printers generally save time and material by making the interior region of the printed object not completely solid. The inside region of the 3d printed object is called as “Infill” and can be made with lots of different patterns, though hexagonal is shown below and rectilinear grid are most common. A higher density infill can contribute to the strength of an object.
