Beschreibung
Zusammenfassung:	A method of fabricating an object, comprising depositing a first layer of first object material on a support substrate electrode; applying a conductive agent material onto the first layer; depositing a first layer of charged powder on an intermediate substrate; conveying the first layer of charged powder on the intermediate substrate proximate to the first layer of first object material; and applying a transferring electric field to cause transfer of the first layer of charged powder from the intermediate substrate onto the first layer on the support substrate electrode, to form a first powder layer on the first layer on the support substrate electrode. Multiple powder layers may be deposited on the first layer. The method may be further comprised of fusing the powder layer(s) to form a first fused layer on the support substrate electrode. A related object fabrication apparatus is also disclosed.
