We often get asked how we calculate our flow rate.

The flow rate is calculated based on the following parameters:

  1. Nozzle (extrusion) width, as specified on the head (or, optionally, in gcode); should match the extrusion width in your recipe and gcode.
  2. Layer thickness (height), as specified in your gcode. Width times Height tells us the Cross Section of your print path.
  3. X/Y/Z distance to move from current position, as specified in your gcode. Cross Section times Distance tells us the Volume to be printed this move.
  4. Print speed, as specified in your gcode. Volume divided by print speed tells us how many nl per second to dispense.
  5. Pulses/nl, as specified on the head (or, optionally, in gcode). Pulses/nl times nl/second tells us how many pulses per second to dispense.
  6. Feed Rate %, as specified on the head (or, optionally, in gcode). Feed Rate % is a direct modifier of your other calculations; 1.00 = no modification; 0.90 means 10% less flow, etc.
