Abstract: An exemplary mold assembly includes a mold providing a cavity, and a heating element configured to heat a first portion of the mold at a first rate to melt a first amount of metal powder within the cavity, and further configured to heat a second portion of the mold at a different second rate to melt a second amount of powder within the cavity. The heating element includes a portion on a first side of the cavity and a portion on an opposing, second side of the cavity. The heating element is configured to receive the mold such that the heating element extends circumferentially about an entire perimeter of the mold.

Abstract: A method of forming an object includes installing multiple foil drums within a processing chamber of an ultrasonic consolidation system. The multiple foil drums each include different materials than the other foil drums. The multiple foil drums are positioned so that one of the foils is selected to be placed on top of the build platform. The selected foil is welded onto the build platform or onto a previously processed layer. A portion of the welded foil is then cut. The multiple foil drums are retracted away from the build platform. The portion of the welded foil that was just cut is then consolidated to the object. The build platform is incrementally lowered before the process is repeated to form the next layer of the object.

Abstract: A build plate for an additive manufacturing system is disclosed. The build plate includes a support structure, a sub-plate, and one or more transducers. The support structure is configured to support a stack of sintered layers of a pulverant material. Further, the support structure extends orthogonally to a build direction. The sub-plate is arranged along the support structure, and defines a transducer cavity. One or more transducers are arranged in the transducer cavities. The one or more transducers are operable to cause vibration of the support structure and the stack parallel to the build direction. Such vibration relieves internal stresses caused by sintering of the stack.

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.
