Abstract: 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.

Abstract: A three-dimensional (3D) printer includes an ejector and a coil wrapped at least partially around the ejector. The 3D printer also includes a power source configured to transmit voltage pulses to the coil. The 3D printer includes a computing system causing one or more drops of the liquid to be jetted out of the nozzle, and a vibrational source configured to transmit vibrational energy towards the printing material.

The vibrational source may include a piezoelectric source, ultrasonic source, a focused acoustic energy source, a laser vibrational source, or combinations thereof.

Abstract: A three-dimensional (3D) metal object manufacturing apparatus has a volume of thermally insulative fluid in which a X-Y translation mechanism moves to position a platform opposite an ejector head. The apparatus also includes a housing having an internal volume in which the platform and X-Y translation mechanism are located. The thermally insulative fluid is a molten salt, such as a molten fluoride, chloride, or nitrate molten salt. The thermally insulative layer protects the X-Y mechanism while the housing helps keep the surface temperature of the object being formed on the platform in an optimal range for bonding of melted metal drops ejected from the ejector head to a surface of a metal object being formed on the platform.

Abstract: 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.
