Abstract

An apparatus provides a method for transferring infiltrant to a 3D printed article comprising the steps of (i) calculating the amount of infiltrant based in part upon the particulars of the 3D printed articles; (ii) dispensing the calculated amount of infiltrant to a scale from an infiltrant dispenser through a controller; (iii) weighing the dispensed infiltrant during the dispensing; providing the controller with a signal of the weighed dispensed infiltrant; and (iv) automatically stopping the infiltrant dispenser through the controller as the weighed infiltrant reaches the calculated amount of infiltrant.
