Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize rail support structures in the process of building objects, as well as novel rail support structures to be used within these AM processes. The rail support structures include a plurality of substantially parallel vertical walls, each wall extending substantially parallel to a direction from the first side to the second side. Adjacent walls of the plurality of substantially parallel vertical walls are separated by a portion of unfused powder. An object is formed above the plurality of substantially parallel vertical walls.

Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize table support structures in the process of building objects, as well as novel table support structures to be used within these AM processes. The table support structures include a first leg portion extending vertically from a build platform; a platform portion including a horizontal top surface supported on the first leg portion; and a plurality of supports extending from the platform portion to a downfacing surface of the object.
