Flow Rate Calculator — Volumetric Extrusion
Calculate volumetric flow rate from print speed, layer height and line width.
How We Calculate This
Formula
- Flow rate = Print speed x Layer height x Line width (mm³/s)
- Filament feed speed = Flow rate / Filament cross-section area
The filament feed speed tells you how fast the extruder gear must push the filament to achieve the desired flow rate.
