  • Patent number: 11192296
    Abstract: A method is provided for additive manufacturing. This method includes monitoring a current to a recoater blade. The monitored current is compared to a predetermined current. An operation is initiated in response to the monitored current exceeding the predetermined current. Another method for additive manufacturing includes comparing a movement of a recoater blade to an expected movement. A single exposure sequence is initiated in response to movement of the recoater blade being different than an expected movement. An additive manufacturing system is also provided which includes a recoated blade and a control. The control is operable to identify resistance to movement of the recoater blade.
    Type: Grant

  • Patent number: 10549520
    Abstract: A structure includes a first body section that has a wall that spans in a vertical direction. The wall has a relatively thin thickness with respect to a length and a width of the wall. A second body section is arranged next to, but spaced apart from, the first body section. A gusset connects the first body section and the second body section. The gusset extends obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting. The first body section has a geometry that corresponds to an end-use component exclusive of the gusset.

  • Patent number: 10265772
    Abstract: A solid freeform manufacturing system includes a manufacturing chamber containing a powder based additive manufacturing device. The manufacturing chamber is connected to an environmental control chamber. The environmental control chamber contains environmental control devices including fans, filters, and an inert gas source. An interconnection between the environmental control chamber and manufacturing chamber allows an inert, contaminant free manufacturing environment.

  • Patent number: 9486963
    Abstract: A powder-derived, non-finished work piece includes a first body section that has a wall that spans in a vertical direction. The wall has a relatively thin thickness with respect to a length and a width of the wall. A second body section is arranged next to, but spaced apart from, the first body section. A gusset connects the first body section and the second body section. The gusset extends obliquely from the wall of the first body section with respect to the vertical direction such that the gusset is self-supporting. The first body section has a geometry that corresponds to an end-use component exclusive of the gusset.
