  • Methods and devices for automatically clearing a print head of a three-dimensional printing device
    Patent number: 11298879
    Abstract: Methods and devices for automatically cleaning a print head within a three-dimensional (3D) printer are disclosed. The methods generally include operating a measurement system (of a 3D printer) to measure an amount of material delivered to a print head of the 3D printer (on a per unit of time basis); detecting a disturbance in the material being delivered to the print head; and retracting the material and then re-introducing the material to the print head. The methods include having a first drive system and a second drive system being used to retract the material and, once the print head is cleaned, to re-introduce the material to the print head with increasing speed from zero to a pre-defined end point speed.
