Infill Density & Patterns
Infill is the internal structure printed inside the solid outer walls (perimeters) of a 3D model. Instead of printing parts 100% solid, slicers generate hollow internal lattices with customizable percentage densities (typically 10%–25%) and geometric patterns.
Infill is one of the strongest cost levers in FDM. Raising it increases filament weight (and therefore material cost) while adding print time; lowering it reduces both. The estimator recalculates weight and time together whenever infill changes.

Common infill geometries include Gyroid (uniform 3D strength in all directions without nozzle crossing), Grid (fast 2D structure), Honeycomb (high strength-to-weight ratio), and Adaptive Cubic (denser near top surfaces to minimize filament consumption).
Choosing Infill Density by Application
Visual decorative figurines and display models typically use 10%–15% infill to minimize cost and print time. Functional mechanical brackets, gears, and outdoor fixtures benefit from 30%–50% Gyroid infill alongside 4–6 solid wall perimeters.
Impact on Print Quotes & Material Savings
Decreasing infill from 40% to 15% can reduce filament weight by 35% and cut print time by up to 25%, significantly lowering the final quote for client orders.
