Abstract

See full text

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.
