WebFeed Rate Vs Flow Rate in 3D Printing. Feed Rate and Flow Rate are two very different things in 3D printing. The Feed Rate refers to the speed at which the axes move, including the extruder, while the Flow Rate refers to the volume of filament that is fed to the nozzle in a set timeframe. Flow Rate is also referred to as the Extrusion Multiplier. WebBy slowing the speed down to 1365 rpm the pump develops 40 ft and intersects our system curve with a flow rate of 300 gpm. By further slowing down the pump to 905 rpm the pump develops 17.5 ft of head which intersects the system curve at 200 gpm. The way the pump speeds are determined is by adjusting speed on the known pump curve (in this case ...
