Abstract: In one aspect, an additive manufacturing system is provided. The additive manufacturing system includes a build platform, a first plurality of particles positioned on the build platform, and a particle containment system positioned on the build platform. The particle containment system includes a particle containment wall. The particle containment wall at least partially surrounds the first plurality of particles and includes a second plurality of particles consolidated together. The particle containment wall includes a top end spaced apart from the build platform, an inner face positioned against the first plurality of particles and extending between the build platform and the top end, and an outer face that faces a substantially particle-free region, the outer face positioned opposite the inner face and extending between the build platform and the top end.

Abstract: An electrochemical cell is presented. The cell includes a housing having an interior surface defining a volume, and an elongated separator disposed in the housing volume. The elongated separator defines an axis of the cell. The separator has an inner surface and an outer surface. The inner surface of the separator defines a first compartment. The outer surface of the separator and the interior surface of the housing define a second compartment having a volume. The cell further includes a conductive matrix disposed in at least a portion of the second compartment volume such that the conductive matrix occupies a gap between the outer surface of the separator and the interior surface of the housing. The gap in the second compartment extends in a direction substantially perpendicular to the axis of the cell.

Abstract: An additive manufacturing system including a housing configured to contain a powder bed of material, and an array of laser emitters having a field of view. The array is configured to melt at least a portion of the powder bed within the field of view as the array translates relative to the powder bed. The system further includes a spatter collection device including a diffuser configured to discharge a stream of gas across the powder bed, and a collector configured to receive the stream of gas and contaminants entrained in the stream of gas. The collector is spaced from the diffuser such that a collection zone is defined therebetween, and the spatter collection device is configured to translate relative to the powder bed such that the collection zone overlaps with the field of view of the array.
