  • Patent number: 11097482
    Abstract: A three-dimensional (3D) object printer includes a surface treatment system configured to treat layers of an object being formed by the printer with a moving ultraviolet (UV) laser. The movement of the laser is controlled with a scanning mirror system and the spot size of the laser is reduced with a focus lens having a numerical aperture in a range of about 0.5 to about 1.0.

  • Patent number: 10391757
    Abstract: A printer is configured with positioning members that hold components at predetermined positions to enable a controller operating at least one printhead in a three-dimensional object printer to form structure about the components. The positioning members can then be removed from the printed three-dimensional object to enable continued formation of the three-dimensional object.

  • Patent number: 10144206
    Abstract: A method of removing support material attached to an object printed with build material by a three-dimensional object printer achieves reliable removal of the support material in a short time. The method includes moving a first dry absorbent media into a volume within a vessel having at least one wall and moving the object into the volume of the vessel. The vessel is agitated to enable the first dry absorbent media to dislodge and absorb the support material from the object, and the first dry absorbent media is moved from the volume of the vessel.

  • Patent number: 10000051
    Abstract: A method of manufacturing a three-dimensional object facilitates removal of the three-dimensional object from the platen on which the object was formed. The method includes rotating the platen from a horizontally level position to a position at an angle to the level position to enable gravity to urge the three-dimensional object away from the platen and inductively heating the platen to melt support material at the boundary of the object and the platen to release the three-dimensional object from the platen.

  • Publication number: 20170100927
    Abstract: Embossing methods and systems include a substrate (e.g., a sheet of paper or other material) delivered through a rendering device (e.g., a printer). An array of time-delayed pins can be driven into the substrate as the substrate travels through an in-line path provided by the rendering device to produce a latent embossed image composed of a combination of shapes depressed in the substrate. An ATA (Acoustic Transfer Assist) system can transfer an image to the substrate. The substrate with the latent embossed image is then transferred to the ATA system and the substrate is rendered with an embossed image based on the latent embossed image.

  • Patent number: 9493397
    Abstract: Ionomers comprising ionic groups such as, for example, tetraalkylammonium groups and methods of making such ionomers. For example, the ionomers can be produced by ring opening metathesis polymerization of alkene-containing monomers with tetraalkylammonium groups and, optionally, alkene-containing monomers without tetraalkylammonium groups. The ionomers can be used in applications such as, for example, fuel cell applications.

  • Publication number: 20160159117
    Abstract: Apparatuses include a conveyor moving in a processing direction, a print head positioned adjacent the conveyor, a light source positioned adjacent a first side of the conveyor, a movable mirror positioned adjacent a second side of the conveyor, that is across the conveyor from the first side of the conveyor, a fixed mirror positioned adjacent the first side of the conveyor (the fixed mirror is between the light source and the print head), and a light sensor position adjacent the second side of the conveyor. The light sensor is between the movable mirror and the print head. The light source outputs light to the movable mirror across the conveyor, the movable mirror directs the light back across the conveyor to the fixed mirror, and the fixed mirror directs the light again across the conveyor to the light sensor.

  • Patent number: 8334887
    Abstract: An apparatus (100) and method (200) that determines beam delays in a printing device is disclosed. The apparatus can include a photosensitive surface (110) and a raster output scanner (120) optically coupled to the photosensitive surface, an integrated scan detector (130) configured to detect the beams from the raster output scanner and configured to produce a signal based on the beams detected from the raster output scanner, and a beam calibration controller (140) coupled to the integrated scan detector. The beam calibration controller can be configured to determine at least one beam delay between the first optical emitter and the at least one second optical emitter based on signals from the integrated scan detector and can also be configured to delay operation between the first optical emitter and the at least one second optical emitter based on the at least one beam delay.
