Vibrational densification of powder supply in additive manufacturing

Disclosed are an apparatus and method for densifying or compacting powder material in the supply bin of an additive manufacture machine to improve the quality of the object being made. For example, a removable or portable apparatus can be applied to the surface of the supply bin once the bin has been filled. The apparatus can include a vibrational component that agitates the underlying powder to compact the material. The apparatus can then be removed during the remainder of the additive manufacturing process, which then follows in its normal course. A vacuum can also be used the remove of air or other gases that are emitted during the compaction process, for example, as voids are filled during densification.

Methods for forming near net-shape metal parts from binderless metal powder
09782828 · 2017-10-10 · ·

Systems and methods for forming near net-shape metal parts from binderless metal powder are disclosed. Systems include a mold die that defines a die cavity and may include one or more ultrasonic transducers operatively coupled to the mold die. Systems may be configured to introduce binderless metal powder into a die cavity and/or to compact the binderless metal powder within the die cavity. Methods include introducing binderless metal powder into a die cavity of a mold die and compacting the binderless metal powder within the die cavity to form a green part within the die cavity. The binderless metal powder may include spheroidal metal particles and angular metal particles. The methods may further include separating the green part from the mold die and sintering the green part, after separating, to form a sintered near net-shape metal part.

Powder packing methods and apparatus

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.
