  • Publication number: 20200180227
    Abstract: The present invention relates to apparatuses for distributing build powder in powder-layer three-dimensional printers (2) and for the collection of particulates of the build powder that have become suspended in the gaseous atmosphere in the vicinity of the build platform of the three-dimensional printer. These apparatuses include recoaters (20) that are particularly useful in providing uniform distribution of fine build powder across the width of the build platform or powder bed. The present invention also includes powder-layer three-dimensional printers (2) which comprise such apparatuses for distributing build powder and/or apparatuses for collecting such suspended particulates. The improved fine powder recoater (20) uses an ultrasonic transducer (30) to move powder through a sheet screen (28). The sheet screen (28) may be presented to the powder fed onto it in a narrow dispensing slot to limit the flow rate of powder from the dispenser and to provide control over the amount of powder dispensed.

  • Publication number: 20200147884
    Abstract: The present invention relates to powder-layer three-dimensional printers (2) having a discrete supply hopper (340) and a recoater (20). The discrete supply hopper (340) is configured to transfer a build powder to the recoater (20) in a manner that enhances the uniformity of build powder layers that are dispensed from the recoater (20). In some embodiments, at least one of the discrete supply hopper and the powder hopper of the recoater is adapted to selectively contact the other, seal against the other, and/or have one partially inserted inside the other so as to diminish or prevent powder pluming during the transfer of build powder from the discrete supply hopper to the recoater.

  • Publication number: 20200080614
    Abstract: A hydraulic mount apparatus includes a housing having an upper portion and a lower portion disposed on a center axis and defining a housing chamber. A partition member is disposed in the housing chamber dividing the housing chamber into a pumping chamber and a receiving chamber. The pumping chamber extends between the upper portion and the partition member. The receiving chamber extends between the lower portion and the partition member. A decoupler is attached to the partition member separating the pumping chamber and the receiving chamber. A moving member is disposed in the pumping chamber and attached to the decoupler. The moving member is made from a non-elastomeric polymer sheet secured to the decoupler for providing the additional damping force.

  • Publication number: 20200001530
    Abstract: Powder layer smoothing devices (34) adapted for use with powder-layer three-dimensional printers (10) are described. The smoothing devices (34) include a counter rotating roller (36, 50, 60) having a complex powder engaging face (38) that may include a series or plurality of flutes (54) or may include knurling (64) extending along at least a portion of the counter rotating roller (36, 50, 60) along its rotational axis (56, 66). The smoothing device (34) may also include a vertically adjustable finishing roller (35) to follow the counter rotating roller (36, 50, 60) across the build box (12) of the powder-layer three-dimensional printer (10).

  • Patent number: 9446448
    Abstract: Recoaters for powder-layer three-dimensional printers which are capable of producing enhanced powder layer uniformity and powder-layer three-dimensional printers having such recoaters are described. The recoater comprises a bridge, two supports, one at either end of the bridge, a powder reservoir, and a substantially rectangular plate which extends between the two supports and contains an opening through which the powder reservoir either extends into or through or through which build powder can be fed into the powder reservoir. The plate has a length to minimum width ratio of no more than about 7.0 and a length to maximum width ratio of no more than about 5.0, the plate being adapted to brace the bridge into a perpendicular relationship with the first and second supports when the recoater is being controllably moved and the powder reservoir is dispensing powder to form a powder layer.
