Abstract: A method includes illuminating a drop with a pulse of light from a light source. A duration of the pulse of light is from about 0.0001 seconds to about 0.1 seconds. The method also includes capturing an image, video, or both of the drop. The method also includes detecting the drop in the image, the video, or both. The method also includes characterizing the drop after the drop is detected. Characterizing the drop includes determining a size of the drop, a location of the drop, or both in the image, the video, or both.

Abstract: A method includes capturing a video of a plurality of drops being jetted through a nozzle of a printer. The method also includes measuring a signal proximate to the nozzle based at least partially upon the video. The method also includes determining one or more metrics that characterize a behavior of the drops based at least partially upon the signal.

Abstract: A method for identifying an angular deviation in the orientation of a multi-nozzle extruder includes moving the multi-nozzle extruder in a first process direction to form a first extrusion material swath and moving the multi-nozzle extruder in a second process direction opposing the first process direction to form a second extrusion material swath. The method further includes identifying widths and heights of the swaths from scanned image data and identifying a component of angular deviation for the multi-nozzle extruder with reference to at least one of a difference between the first swath width and the second swath width and another difference between the first swath height and the second swath height.

Abstract: An electrostatic ink jet printhead having an electrostatic actuator with improved resistance to adverse effects resulting from misalignment of a body layer to a gap standoff layer. In an embodiment, first and second portions of the gap standoff layer each have a first width and first and second sections of the body have each have a second width that is wider than the first width. Even with an amount of misalignment, the first and second sections of the body layer define nodes for an actuator membrane, thereby maintaining an effective width (WE) of the actuator membrane that is equal to a target width (WT) of the actuator membrane.

Abstract: A method and structure for forming an ink jet printhead can include the use of a transfer pad to transfer an adhesive solution to an ink jet printhead substrate. The adhesive solution can be placed within a patterned recess of a cliché and then an upper surface of the adhesive solution can be gelled. A surface of the transfer pad contacts the gelled upper surface and transfers the adhesive solution to the ink jet printhead substrate. During the transfer, a lower surface of the adhesive solution gels. During contact with the ink jet printhead substrate, the gelled lower surface adheres to the ink jet printhead substrate while the gelled upper surface releases from the transfer pad.

Abstract: A 3D printer includes a nozzle and a camera configured to capture an image, a video, or both of a plurality of drops of liquid metal being jetted through the nozzle. The 3D printer also includes a computing system configured to measure a signal proximate to the nozzle based at least partially upon the image, the video, or both. The computing system is also configured to determine one or more metrics that characterize a behavior of the drops based at least partially upon the signal.

Abstract: An apparatus includes a heater for converting a filament of extrusion material into thermoplastic material. The heater has a channel configured to change the cross-sectional shape of the filament to a cross-sectional shape that has a greater surface area than the surface area of the filament before the heater receives the filament. The channel of the heater can also be configured to drive the center portion of the filament toward the heated walls of the channel and to mix thermoplastic material in the channel while exposing the center portion of the filament to the heated wall of the channel.
