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 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.
