Estimate 3D printing filament usage in grams and meters from model volume and infill. Plan material costs and spool requirements for FDM print jobs.
Calculate optimal layer height from nozzle diameter and print quality target. Set layer resolution as a fraction of nozzle size for best FDM results.
Calculate 3D print speed settings from volumetric flow rate and layer dimensions. Set max speed within extruder and hotend flow limits.
Perimeter walls, top solid layers, and bottom solid layers form the shell — always 100% density regardless of infill setting.
Shell volume ≈ surface area × wall thickness + top/bottom × layer areaInternal volume multiplied by infill percentage gives sparse infill mass. Gyroid and grid patterns approximate this percentage closely.
Infill volume = internal volume × (infill% / 100)Total volume times material density yields weight. Common FDM densities: PLA 1.24, PETG 1.27, ABS 1.04, Nylon 1.14, CF-Nylon 1.30 g/cm³.
Weight (g) = total volume (cm³) × density (g/cm³)Updated: July 2026
Shell ~45 cm³ + infill ~20 cm³ = 65 cm³ × 1.24 g/cm³ ≈ 81 g. Useful for drone component weight budgeting.
Small bracket 30 cm³ total material at 60% effective infill: ~22 cm³ × 1.27 ≈ 28 g. Higher infill increases weight linearly with internal volume.
Vase mode (0% infill, single wall) 200 cm³ shell × 1.24 = 248 g. Significantly lighter than 20% infill version at ~320 g — affects First Class vs Priority shipping.
Even at 100% infill, designed hollow cavities (shell mode, empty interiors) remain empty. 100% fills available internal space only — not the entire bounding box.
Carbon fiber, wood-fill, and metal-fill filaments have different densities (1.3–2.0+ g/cm³). Use manufacturer-specified density for accurate weight.
Part weight affects shipping, structural load, and material cost. This calculator estimates finished print weight from outer dimensions, wall thickness, infill percentage, and filament material density.
