  • Patent number: 10723072
    Abstract: An apparatus for fabricating a 3D object. The apparatus may be comprised of a charged powder transferring system, a first charged powder layer generating device, a second charged powder layer generating device, a powder layer consolidation station, and an object build platform. In operation of the apparatus, a portion of a powder transferring surface of the flexible web traverses a directional change member during cyclic motion, and exceeds a radius of curvature defining a delamination threshold between the powder transferring surface and a first fused slice of the object. The apparatus may include an oven operable to fuse a stack of delaminated fused slices on a support substrate into a fused stack comprising fused second powder material and fused first powder material forming at least a portion of the object. A method of fabricating a 3D object is also disclosed.

  • Patent number: 3990694
    Abstract: A facsimile transceiver apparatus is described which includes means for advancing a document to a station at which location the document is line scanned by a laser light beam. A video signal thus formed is transmitted to a remote facsimile apparatus for reproduction of the document. The transceiver further includes an electrostatographic printing station at which station a latent electrostatic image is formed by line scanning a laser light beam over a uniformly charged photoreceptor surface. A means for line scanning at the document scanning station and at the photoreceptor surface includes a laser light source and means for alternatively sweeping the laser light beam across the document at the scanning station or across a charged image retention surface at the printing station. Means are also described for enhancing document feed, resolution, and speed of reproduction.
