01 / METHOD
How to use this volumetric limit tool
- Enter your tested maximum volumetric flow.
- Set the line width, layer height, and bead model used by the profile.
- Choose a safety margin and use the resulting speed as a ceiling, not a quality promise.
02 / APPLICATIONS
When it is useful
- Cap slicer speeds by material flow
- Compare nozzle and layer-height combinations
- Build a conservative high-speed profile
03 / MODEL
Assumptions and limitations
Assumptions
- The flow limit was measured for the same hotend, nozzle, temperature, and material.
- The chosen cross-section model reasonably represents the slicer path.
- Safety margin is deducted from the entered limit.
Limitations
- Acceleration and short segments may never reach this speed.
- Motion limits, cooling, resonance, layer adhesion, and surface quality can require a much lower speed.
04 / FAQ
Common questions
Where do I get a flow limit?
Use a controlled volumetric-flow test for the exact filament, nozzle, hotend, and temperature.
Why add a safety margin?
Test results and real prints vary. Operating below the observed failure boundary reduces the chance of intermittent under-extrusion.
Is maximum speed safe for every feature?
No. Bridges, overhangs, small layers, and external walls often need lower speeds for quality or cooling.
