Abstract: Techniques for dehumidifying powder used as print material in a powder bed fusion (PBF) three-dimensional (3-D) system are disclosed. A hopper includes one or more ultrasonic transducers (UTs) positioned at strategic locations. When activated, the UTs use sound pressure at ultrasonic frequencies to agitate the powder particles held in the hopper. The movement of the particles drives moisture trapped between the particles into one or more desiccants. In various embodiments, the desiccants may be supported by desiccators suspended in the powder, such as via the casing of the hopper. In other embodiments, the desiccants may be desiccant bags provided in a desiccant insert. The moisture accumulates in the desiccants. Among other advantages, no separate thermal source is needed to dry the powder, which can be provided directly to the PBF 3-D system via the re-coater for depositing layers to form a build piece.

Abstract: A method of additive manufacturing (AM) includes dispensing a first building material formulation to form an outer region, and dispensing a second building material formulation to form an inner region, the outer region surrounding the inner region, the inner and outer regions being shaped to form a layer of the object; exposing the layer to a first curing condition, repeating the dispensing and the exposing to sequentially form a plurality of layers of the object and collectively exposing the plurality of layers to a second curing condition. The selections are such that the first building material formulation is hardened to a higher degree than the second building formulation. The outer regions form a hardened coating that at least partially encapsulates the inner regions. The second curing condition is other than the first curing condition and is selected to increase the degree that the inner region is hardened.
