Peristaltic Pump Ebay.JPG Here is the best inexpensive peristaltic pump I could find with a relatively high flow rate: 500 ml/min for $30 and free shipping. It doesn't provide much info on specs, like rotor RPM, number of rollers (3? 4?), and tubing inner diameter. It does say the in/out hose barbs are for 1/4" tubing, so I expect the pump tube is 1/4" ID also. It may be possible to soup it up with thinner wall tubing, or speeding up the rotor. Regardless, at 500 ml/minute, it could speed up printing.
