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 3D print speed settings from volumetric flow rate and layer dimensions. Set max speed within extruder and hotend flow limits.
Calculate maximum volumetric flow rate for a 3D printer nozzle from temperature and material. Find hotend extrusion limits for speed tuning.
Optimal layer height is 25–75% of nozzle diameter. A 0.4 mm nozzle works best at 0.10–0.30 mm layers. Exceeding 80% of nozzle diameter reduces extrusion consistency.
Layer height = nozzle diameter × quality factor (0.25–0.75)Draft: 50–75% of nozzle (fast, visible layers). Standard: 30–50% (balanced). Fine/detail: 20–30% (slow, smooth surfaces).
Draft 0.28 mm | Standard 0.20 mm | Fine 0.12 mm (0.4 mm nozzle)Layer height should be a multiple of motor step resolution (Z-axis). Common magic numbers for 0.4 mm nozzle: 0.08, 0.12, 0.16, 0.20, 0.24, 0.28 mm.

Standard 0.20 mm layer height (50% rule). Good balance of speed and quality for functional parts at 50–60 mm/s print speed.
Draft 0.36 mm (60%) or standard 0.28 mm (47%). Larger nozzle enables faster volumetric flow for big structural prints.
Fine 0.06–0.08 mm layers (24–32%). Slow print but captures small features on 28 mm scale miniatures.
Layers too thick for the nozzle (e.g., 0.36 mm on 0.4 mm nozzle) produce inconsistent extrusion and poor layer bonding. Upgrade nozzle or reduce layer height.
Thin layers at high speed starve extrusion. Reduce speed or increase temperature when going below 0.12 mm on a 0.4 mm nozzle.
Layer height is the primary resolution control in FDM printing. This calculator recommends optimal layer height as a fraction of nozzle diameter for draft, standard, and fine quality tiers.
