A three-dimensional (3D) object printer has an ejector head with a single nozzle that is fluidly connected to a plurality of orifices in an orifice plate of the ejector head. An ejection of material through the single nozzle is emitted through the plurality of orifices simultaneously. In one embodiment, some of the orifices are oriented at an angle to an axis perpendicular to the orifice plate. This configuration enables a structure to be formed with a predetermined material density without needing to increase the ejection frequency significantly or requiring the printer to incorporate multiple ejector heads.

Fuser, method of fuser manufacture and composition

A three-dimensional (3D) object printer has an ejector head with a single nozzle that is fluidly connected to a plurality of orifices in an orifice plate of the ejector head. An ejection of material through the single nozzle is emitted through the plurality of orifices simultaneously. In one embodiment, some of the orifices are oriented at an angle to a normal to the plane of the orifice plate. A splicer of the printer that generates machine ready instructions for operation of the printer identifies a standoff distance between the orifice plate and a surface onto which drops are being ejected to achieve a target drop spacing for the drops ejected onto the surface. In this manner, a material density for structure within a layer can be achieved without needing to increase the ejection frequency significantly or requiring the printer to incorporate multiple ejector heads.

Nozzles for an additive manufacturing device and methods for improving wettability of the nozzles are disclosed. The method may include subjecting the nozzle to a surface treatment. The surface treatment may include contacting a surface of the nozzle with one or more surface modifying agents. The surface modifying agents may include one or more of an oxidizing agent, an acid, a base, or combinations thereof. The one or more surface modifying agents may increase an oxygen content of the surface of the nozzle. An inner surface of the nozzle may have a water contact angle of greater than 1&#xb0; and less than about 90&#xb0;. The inner surface of the nozzle may be free or substantially free of a coating.

A three-dimensional (3D) metal object manufacturing apparatus selects operational parameters for operation of the printer to form vias in substrates. The apparatus identifies the bulk metal being melted for ejection and uses this identification data to select the operational parameters. The apparatus identifies the via holes in the substrate and positions an ejector opposite the via holes to eject drops of melted bulk metal toward the via holes to fill the via holes.
