A method for 3D printing includes printing a first metallic material on a substrate as a support structure (48). A second metallic material, which is less anodic than the first metallic material, is printed on the substrate as a target structure (46), in contact with the support structure. The support structure is chemically removed from the target structure by applying a galvanic effect to selectively corrode the first metallic material.

A three-dimensional (3D) metal object manufacturing apparatus has a thermally insulative layer between a platform on which an ejection head ejects drops of melted metal and a X-Y translation mechanism on which the platform is moved within an X-Y plane opposite the ejection head. The apparatus also includes a housing having an internal volume in which the platform and X-Y translation mechanism are located. In one embodiment, the thermally insulative layer is a plurality of spheres made of a thermally insulative material such as a ceramic made of zirconium dioxide or zirconium oxide. The thermally insulative layer protects the X-Y mechanism while the housing helps keep the surface temperature of the object being formed on the platform in an optimal range for bonding of the ejected melted metal drops to the object's surface.
