What is infill percentage in 3D printing?

The term "Fill Percentage" is usually used for FDM(FFF) 3D printing. How to choose the right fill type and percentage and what it can affect during further operation. How to reduce the cost of 3D printing without harming the model.

The density of the interior of your part when XNUMXD printed is called infill. The ratio of the filled space to the total internal volume of your part is called the percentage of infill in XNUMXD printing. Infill in XNUMXD printing can be done in the following ways:

The percentage of Infill affects the strength when this parameter increases, and the lightness when it decreases. As a rule, 50D printing is calculated based on the material spent on printing, taking into account the support, so the cost of your part also depends on the percentage of Infill. At the same time, it has been proven experimentally that printing with a Infill of more than XNUMX% does not make any sense. The part does not become stronger from this. It is important to find a certain balance between the cost and mechanical parameters of your part.

But what really affects the mechanical parameters of printed products is the wall thickness. Set when preparing a part for printing. Sometimes with a minimum Infill, but with a solid wall thickness, the parts turned out to be stronger than with a large Infill and low thickness.
