Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support surrounding structures in the process of building objects, as well as novel surrounding support structures to be used within these AM processes. The support structure surrounds at least a portion of the object with a continuous thickness of powder disposed between the support structure and the object, the continuous thickness of powder having a maximum thickness that does not exceed 10 mm.

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 connecting support structures in the process of building objects, as well as novel connecting support structures to be used within these AM processes. The connecting support structures include two fused connections to the object and an axial direction between the fused connections, a perimeter of fused material about the axial direction, and unfused powder or air completely surrounding the perimeter of fused material.

Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support leading edge structures in the process of building objects, as well as novel leading edge support structures to be used within these AM processes. The support structure is positioned adjacent the object between the object and a first side of the powder bed. The support structure has a shape that tapers outward in the direction from the first side to the object

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.
