In FDM (Fused Deposition Modeling) 3D printing, Infill Density and Infill Patterns define the internal structure of a printed part.
In FDM (Fused Deposition Modeling) 3D printing, Infill Density and Infill Patterns define the internal structure of a printed part. FDM parts are rarely printed 100% solid, as this increases print time, material usage, thermal warping, and cost. Instead, the slicer generates an internal cellular lattice structure wrapped in a solid outer shell (perimeters, top, and bottom layers).
Understanding the physical behavior of these lattices requires entering the domain of cellular solids mechanics. The mechanical properties of these structures are analyzed using the Gibson-Ashby model, which relates the relative density of the lattice to its mechanical properties:
