  • Patent number: 11325310
    Abstract: An optimal printing speed and orientation for an object to be manufactured using an additive manufacturing process in which a photo-curable resin is cured through exposure to radiation are estimated by determining, for pixel maps defining cross-sections of the object, a critical size of a convolution kernel which provides an activation map having a maximum activation pixel value less than or equal to a predetermined threshold value. For each respective pixel map, a printing time is estimated as a function of an adjusted base lift velocity and base lift height of the printing apparatus. The optimal printing speed and orientation are then estimated as a minimum value of a function of the printing times for all respective pixel maps of the cross-sections of the object at each of a plurality of possible orientations of the object.

At least a portion of the cathode substantially encompasses the anode to electrically shield the anode from the Faraday cage ensuring the formation of an e-field between the anode and cathode instead of the anode and the Faraday cage upon energizing the RF generator.

  • Patent number: 9737440
    Abstract: Printed articles having unique data thereon, and flexible substrate printing systems and methods that allow for customization of flexible, absorbent substrates. Customization is accomplished by printing variable data on substrate stock in a single run or production pass such that at least some of the articles in a set of articles contains printed matter different from printed matter on other articles in the same set. The substrate stock can include napkin material, toilet tissue material, paper towel material, or any other similar substrate. One or more print engines are configured to receive substrate stock from the conveyor and print variable matter on the substrate stock. The methods and systems allow for economical and efficient production of small or large customer orders without the need to produce individual printing dies or plates.

  • Patent number: 9592674
    Abstract: A liquid droplet ejecting apparatus includes a transport unit configured to transport a medium in a transport direction, a support configured to support the medium transported by the transport unit, a liquid droplet ejecting portion configured to eject liquid droplets to the medium supported by the support, a carriage configured to reciprocate in a scanning direction intersecting the transport direction while holding the liquid droplet ejecting portion, and an air flow generator configured to create an air flow in an area over the support. The air flow generator limits creation of the air flow when the liquid droplet ejecting portion faces the medium in an ejection direction and allows the creation of the air flow when the liquid droplet ejecting portion does not face the medium in the ejection direction, due to movement of the carriage in the scanning direction.

  • Patent number: 9281093
    Abstract: Known operating processes for an irradiation device for irradiating a substrate by a UV emitter include the process steps of: (a) operating the UV emitter at a nominal operating radiation power; (b) continuously feeding the substrate at a feed rate into the irradiation field; and (c) irradiating the substrate in the irradiation field defined by the UV emitter. In order to devise, on this basis, a simple and inexpensive operating process for an irradiation device, which makes a short start-up time feasible after an interruption of the production process, the UV emitter is switched off when there is an interruption of the continuous substrate feed. The emitter temperature of the switched-off UV emitter is measured, and provisions are made for counter-measures to counteract a decrease of the emitter temperature by more than 10° C. below the nominal operating temperature.

  • Patent number: 9061529
    Abstract: Each unit of an inkjet printing station includes chains arranged along a transportation path of a web paper. A holding mechanism is fixedly arranged on the chain. The holding mechanism holds both ends of a paper passing bar to which the web paper is attached. Driving the chain with a handle causes the holding mechanism to move. The paper passing bar is delivered between the units adjoining each other. Therefore, the paper passing bar is movable from one end to the other end of the inkjet printing station formed by the units. Moreover, when specifications are changed for changing combination of the units, the combination can be made optionally.
