3D Printer Volumetric Flow Calculator
Calculate volumetric extrusion flow in mm³/s from extrusion width, layer height, and print speed.
What this tool does
Calculate volumetric extrusion flow in mm³/s from extrusion width, layer height, and print speed.
Where this tool is useful
Estimate hotend load for a planned FDM print; actual flow depends on bead geometry.

Common questions
What can I use this for?
Estimate hotend load for a planned FDM print; actual flow depends on bead geometry.
What does the tool accept?
Fill in the numeric measurements and units shown in each field.
What should I check before using the output?
This uses the common rectangular bead-area approximation; real extrusion geometry may differ and flow capacity depends on material and hotend.
Does my input leave my device?
The utility runs in your browser. Selected content is not transmitted to a freedropper conversion service.
How can I reuse the result?
Copy the output or use the download control when the tool produces a file. Check the target application accepts the resulting syntax or file type.
