Abstract

A method of fabricating an object, comprising direct depositing a first layer of first object material on a support substrate electrode; applying a conductive agent material onto the first layer; direct depositing a first layer of charged powder 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 direct 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.
