WebJan 19, 2024 · Printer 1 – 30 mm/s print speed, 50% feed rate, 110% flow rate. Printer 2 – 30 mm/s print speed, 100% feed rate, 100% flow rate. Assuming these printers, the filaments, and the models they print are identical, Printer 2 would finish printing the model roughly twice as fast as Printer 1 due to the higher feed rate.
