Abstract: A method of additive manufacturing includes supplying additive manufacturing powder to a build area of an additive manufacturing machine. The method includes fusing a portion of the powder to form a part, and removing a non-fused portion of the powder from the build area into a removable vessel for storing non-fused powder after building a part. The method can include supplying additive manufacturing powder to a build area, fusing a portion of the powder, and removing a non-fused portion of the powder all on a single discrete lot of additive manufacturing powder without mixing lots.

Abstract: In some examples, a client device may send, to a service computing device over a network, a request for information related to a change to a file system associated with the client device. In response, the client device may receive, from the service computing device, a list of one or more changes to the file system. The client device may add and/or update metadata for a stub file on the client device based at least partially on the received list of one or more changes. In some cases, the stub file may include a stub data structure stored on the client device, while the file content of the file corresponding to the stub file may be stored at a storage over the network.
