Fill Density Fill density, also known as infill density, determines how much of a 3D-printed object’s interior is solid. It is expressed as a percentage and ranges from 0% (hollow) to 100% (completely solid). Lower fill densities reduce material use and print time, making them ideal for decorative objects or prototypes, while higher densities provide increased strength and durability for functional parts. Slicing software allows users to select various infill patterns, such as grid, honeycomb, or gyroid, which can affect the object’s weight, strength, and print time. Choosing the right fill density is essential for balancing performance and efficiency in 3D printing projects. |
