Infill
Definition
Infill is the internal, usually partly hollow pattern inside a 3D print. It determines how solid and strong a part is: more infill means stronger and heavier, less infill lighter and faster.
For most parts 15 to 25% infill is enough. Only heavily loaded parts need more. Choosing the right infill saves both material and print time — and therefore cost.
