![]() Thus the need for calibrating the filament flow rate. Naturally for many instances this is either too much, or on the odd occasion too little. Hence by default 3D printing slicers set the flow rate to 1.0 or 100%. Consequentially dimensional accuracy and line widths all go out of the window, as there is no benchmark to calculate from. They don’t know exactly how much molten plastic is being pushed through the nozzle. But when a slicer program like Cura, PrusaSlicer, or Simplif圓D calculate the g-code. Moreover the additives, type of plastic used and so on. ![]() Next comes the characteristics of the filament itself. Firstly involves calibrating the extruder stepper motor steps, so the firmware knows exactly how much solid filament is pushed through the extruder. But why does filament flow rate change so much?įundamentally there are two sides of this answer. Hence calibrating the filament flow rate is a crucial step in 3D printing. Especially as they can change from the same manufacture and same model of 3D printer. Naturally 3D slicer software don’t know what the individual printers requirements are. Namely the filament flow rate is the rate as which the 3D printer extrudes the molten filament. ![]() So what is the filament flow rate exactly? Calibrating the flow rate within Cura, PrusaSlicer, or Simplif圓D for each filament is as crucial as calibrating the extruders stepper motor.
