Abstract: The present disclosure relates generally to methods and apparatuses for additive manufacturing using reduced amounts of powder-based built materials. Such methods and apparatuses mitigate several drawbacks of conventional power-based methods, including high powder overhead, increased costs, ergonomic strain on machine operators, health risks, and risk of short powder feeds.

Abstract: The present disclosure generally relates to powder packing for additive manufacturing (AM) methods and systems. Conventional powder packing methods are manual and non-standardized, and they result in operator fatigue and potentially product inconsistencies. Powder packing according to the present disclosure improves standardization and reduces turnaround time, with the potential to lower the cost of AM.

Abstract: The present disclosure generally relates to methods for additive manufacturing (AM) that utilize spoke support structures in the process of building objects, as well as novel spoke support structures to be used within these AM processes. The object includes a first portion and a second portion. A first distal end of the first portion is separated from a second distal end of the second portion by a portion of unfused powder. At least one support structure connects the first distal end to the second distal end. The method includes removing the object and the support structure from the powder bed. The method includes heat treating the object and the support structure. The support structure maintains dimensional stability of the object during the heat treatment. The method includes machining away the support structure from the first distal end and the second distal end after the heat treatment.
