Abstract
Methods of fabricating a printhead having integrated inkjet nozzles are disclosed. The methods include injection molding the printhead having a plurality of manifold features and embossing jet features extending between the manifold features and an outer surface of the printhead.
Claims20
A method comprising:
- injection molding a printhead, the printhead including a plurality of manifold features that lead up to a nozzle surface layer;
- filling the manifold features with a sacrificial material;
- heating the nozzle surface layer to above a glass transition temperature;
- embossing jet features via members that penetrate through the nozzle surface layer to the sacrificial material;
- and
- removing the sacrificial material.

A method comprising:
- injection molding a printhead, the printhead including a plurality of manifold features that include voids at an outer surface of the printhead;
- filling the manifold features with a sacrificial material;
- covering the outer surface with a melted polymer that forms a nozzle surface layer over the voids;
- embossing jet features via members that penetrate through the nozzle surface layer to the sacrificial material;
- and
- removing the sacrificial material.
