Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize powder removal ports in the process of building objects, as well as novel support structures including powder removal ports to be used within these AM processes. The objects include walls defining regions of unfused powder. The powder removal ports include at least one tube aligned with an opening in the walls to allow removal of the powder. The methods include removing unfused powder from the enclosed space via the at least one tube.

Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support structure in the process of building objects that may be removed by rotating the support structure to a second orientation before removal, as well as novel support structures to be used within these AM processes. The support structures are fabricated in a first orientation and then rotated to the second orientation. The support structures are removed by passing through an outlet of the object.
