When this helps
Turn a measured volumetric flow limit into an estimated line speed. Start with Measured maximum volumetric flow; this calculator reports Speed from rounded bead.
Tools · Flow and speed
Speed from maximum flow
Turn a measured volumetric flow limit into an estimated line speed.
Results
- Speed from rounded bead
- 147.391309 mm/s
- Speed from rectangular estimate
- 133.333333 mm/s
Method
Speed = measured maximum flow ÷ bead area. Results show rounded and rectangular cross-section estimates.
Worked example
Example inputs
- Measured maximum volumetric flow
- 12 mm³/s
- Extrusion width
- 0.45 mm
- Layer height
- 0.2 mm
Calculated outputs
- Speed from rounded bead
- 147.391309 mm/s
- Speed from rectangular estimate
- 133.333333 mm/s
How to read the result
With these example inputs, Speed from rounded bead is 147.391309 mm/s. Use that value for the setting or decision named above, and read the other outputs as supporting checks.
Common mistake
Do not leave Measured maximum volumetric flow at the example value of 12 mm³/s unless it matches your own measurement.
Assumptions and limits
Enter a limit measured with your own material and hotend. Acceleration, cooling and other speed limits still apply.
