Abstract
A fluid ejection device controller for controlling a fluid ejection device of a three dimensional printing system has a processor and a memory. The memory includes executable instructions that when executed by the processor causes the fluid ejection device controller to control a motion of the fluid ejection device to print agent onto a layer of build material in a build area; and to flush agent through at least one nozzle of the fluid ejection device in response to detecting, by the fluid ejection device controller, an erroneous stopping of the motion of the fluid ejection device and the fluid ejection device being positioned on top of the build area.
Claims10
A fluid ejection device controller for controlling a fluid ejection device of a three dimensional printing system, the fluid ejection device controller comprising a processor and a memory, the memory comprises executable instructions that when executed by the processor causes the fluid ejection device controller to
- control a motion of the fluid ejection device to print agent onto a layer of build material in a build area;
- and
- to flush agent through at least one nozzle of the fluid ejection device in response to detecting, by the fluid ejection device controller, an erroneous stopping of the motion of the fluid ejection device and the fluid ejection device being positioned on top of the build area.
The fluid ejection device controller according to claim 2, wherein the agent comprises at least one of a fusing agent, a binding agent, a detailing agent, a coloring agent and a conductivity changing agent.
A three dimensional printing system comprising:
- a fluid ejection device;
- and
- a fluid ejection device controller for controlling the fluid ejection device;
- wherein the fluid ejection device controller comprises a processor and a memory, the memory comprises executable instructions that when executed by the processor causes the fluid ejection device controller to
- control a motion of the fluid ejection device to print agent onto a layer of build material in a build area;
- and
- to flush agent through at least one nozzle of the fluid ejection device in response to detecting, by the fluid ejection device controller, an erroneous stopping of the motion of the fluid ejection device and the fluid ejection device being positioned on top of the build area.
A method of controlling a fluid ejection device of a three dimensional printing system;
- the method comprising:
- controlling a motion of the fluid ejection device to print agent onto a layer of build material in a build area;
- and
- in response to detecting an erroneous stopping of the motion of the fluid ejection device and the fluid ejection device being positioned on top of the build area, flushing agent through at least one nozzle of the fluid ejection device.
