Abstract
A method for forming a printhead including one or more channels. The method can include depositing and selectively sintering a first layer of powder into a sintered layer that forms a first discrete cross-sectional region of a printhead structure for the printhead. A plurality of layers of powder can be sequentially deposited and selectively sintered into a plurality of sintered layers that form discrete cross-sectional regions of the printhead structure and form at least a portion of at least one or more channels. Each of the plurality of layers of powder is deposited directly onto at least one sintered layer. Each of the plurality of sintered layers is integrally bonded to at least one other sintered layer.
Claims14
A method for forming a printhead, comprising one or more channels, the method comprising:
- selectively sintering a first layer of powder comprising a material to form a first sintered layer, wherein the first sintered layer forms a first cross-sectional region of a printhead structure for the printhead;
- depositing a second layer of powder comprising the material directly onto the first sintered layer;
- selectively sintering the second layer of powder to form a second sintered layer integrally bonded to the first sintered layer and to form at least a portion of at least one of the one or more channels, wherein the second sintered layer further forms a second cross-sectional region of the printhead structure for the printhead adjacent to the first cross-sectional region;
- and
- depositing and selectively sintering one or more additional layers of powder comprising the material to form one or more additional sintered layers until the printhead structure is formed,
- wherein the one or more channels are configured for flowing ink through the printhead structure, and the one or more channels form openings on at least one surface of the printhead structure for the printhead.
