Nozzle Flow Calculator

Estimate volumetric flow from line width, layer height and print speed.

Actual safe flow depends on hotend, filament, temperature and calibration.

How it works

Estimate volumetric flow from line width, layer height and print speed.

Estimating method: Flow = line width × layer height × speed.

Worked example

0.45 mm × 0.2 mm × 80 mm/s gives 7.2 mm³/s.

Common mistakes
  • Ignoring material and temperature limits.
  • Confusing travel speed with print speed.
  • Assuming every hotend can sustain high flow.
