Volumetric flow calculator

A hotend can only melt so much filament per second. That limit decides how fast you can print at a given layer height and line width.

Presets come from Bambu Studio's generic filament profiles: PLA 12 · PLA Silk 7.5 · PETG 8 · ABS 15 · ASA 12 · TPU 3.2 · PC 16 · PA 12 mm³/s. Your hotend and filament brand may differ.

Flow needed

Formula: flow (mm³/s) = speed (mm/s) × layer height (mm) × line width (mm).
