Multiple sources describe practical slicer adjustments that can lower filament consumption on 3D prints. The guidance focuses on changing common print and model parameters rather than redesigning parts from scratch. Recommended areas include tuning layer height to balance detail and material use, adjusting infill density and pattern to reduce internal material, and selecting the number and thickness of perimeters/walls so outer structure remains strong without unnecessary bulk. Sources also emphasize reviewing top and bottom layer counts to avoid overbuilding, since excessive surfaces can increase material consumption. Additional savings are attributed to enabling or optimizing support structures—using fewer supports where possible, adjusting overhang thresholds, and choosing support types that use less material. Finally, sources note that slicers often provide settings for reducing wasted “travel” material and for optimizing print speed/flow so material is used efficiently. Overall, the recommendations aim to achieve the desired strength and appearance while minimizing unnecessary filament, with results varying by printer, material, and part design.
