A three dimensional printing system, the system comprising:
- a printhead;
- and
- a removable tray comprising a reservoir, the tray located in a print bed of the three dimensional printing system such that liquid purged from the printhead is deposited in the reservoir,
- wherein prior to the system purging liquid from the printhead, the system confirms that the tray is in place using a sensor.
1 more element
A tray to capture and dispose of purged liquid, the tray comprising
- a reservoir to receive purged liquid from an installed printhead, and
- absorbent material in the reservoir,
- wherein the tray removably attaches in a printing area of a three dimensional printing system such that the tray is within 1.0 cm of an ejector of the printhead.
A three dimensional printing system, the system comprising:
- a build unit;
- a printhead, the printhead comprising an purgeable liquid and the printhead positioned so that ejected liquid from the printhead is deposited on the build unit;
- a sensor, the sensor to detect placement of a tray in the build unit;
- a controller, wherein the controller:
- detects placement of the tray the build unit using the sensor;
- and
- when the tray is positioned to receive liquid ejected from the printhead, the controller causes the printhead to purge liquid from the printhead.
