A device configured to jet one or more droplets of a viscous medium may include a housing having an inner surface at least partially defining a jetting chamber configured to hold the viscous medium, and a flexible jetting nozzle. The flexible jetting nozzle may include a flexible conduit extending between an inlet orifice in an inner surface to an outlet orifice in an outer surface. The device may cause an increase of internal pressure of viscous medium in the jetting chamber to force one or more droplets of viscous medium through the flexible conduit and through the outlet orifice. The flexible jetting nozzle may include a flexible material. The flexible jetting nozzle may deform, to cause a cross-sectional area of the flexible conduit to dilate, in response to the increase of the internal pressure of the viscous medium in the jetting chamber.

A method for controlling an ejector is disclosed, wherein the ejector comprises an actuator arrangement configured to eject a droplet of viscous medium onto a substrate, and wherein the droplet forms part of a sequence of a plurality of droplets. The method comprises obtaining a control parameter for controlling the operation of the actuator arrangement, and operating the actuator arrangement, using the control parameter, in order to eject the droplet. The obtained control parameter is based on at least one of: a time period between the droplet and a previous droplet in the sequence, a difference in target size of the droplet and a size of the previous droplet in the sequence, and the droplets position in the sequence.

The technology disclosed relates to high utilization of donor material in a writing process using Laser-Induced Forward Transfer. Specifically, the technology relates to reusing, or recycling, unused donor material by recoating target substrates with donor material after a writing process is performed with the target substrate. Further, the technology relates to target substrates including a pattern of discrete separated dots to be individually ejected from the target substrate using LIFT.

A jetting device configured to jet one or more droplets of a viscous medium through a nozzle may include an acoustic transducer configured to emit an acoustic signal that transfers acoustic waves into at least a portion of the viscous medium located in a viscous medium conduit a viscous medium conduit configured to direct a flow of the viscous medium to an outlet of the nozzle. The acoustic signal may be an ultrasonic signal. The acoustic signal may adjust one or more rheological properties of the viscous medium, based on acoustic actuation. The acoustic transducer may be implemented by an actuator of the device that is configured to move through an eject chamber to cause viscous medium to be jetted through the outlet of the nozzle as one or more droplets.

Jetting devices with acoustic transducers and methods of controlling same

A jetting device configured to jet one or more droplets of a viscous medium through the outlet of a nozzle includes an energy output device. The energy output device is configured to direct a quantum of energy into at least a portion of the volume of the viscous medium jetted through the outlet to control a breaking of the droplet from the nozzle. The energy output device may include an acoustic transducer or a piezoelectric material or a laser emitter or a heater.

An apparatus for depositing and/or jetting viscous medium on a surface of a workpiece includes at least two depositing head assemblies. The at least two depositing head assemblies are configured to move in three dimensional space. The at least two depositing head assemblies are also configured to at least one of concurrently and simultaneously deposit the viscous medium on the workpiece.

Methods and devices for jetting viscous medium on workpieces

In a method for jetting droplets of viscous medium on a workpiece, a jetting machine iteratively jets the droplets of viscous medium from a jetting nozzle onto a first surface of the workpiece to form a single continuous mass of material at an edge of the first surface of the workpiece. At least a portion of the single continuous mass of material extends past the edge of the first surface and adheres to a second surface of the workpiece.
