Infill Density

Infill density is the “fullness” of the inside the walls of a part.

This term is most commonly applied to Material Extrusion technology where the slicing software can define the percentage of solidity. This is usually defined as a percentage between 0 and 100, with 0% making a part hollow and 100%, completely solid.

This decision has a significant impact on the part's ultimate weight, its rigidity, its production time and its cost in terms of how much material is required.
