Abstract
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 method for 3D printing, comprising:
- printing a first metallic material on a substrate as a support structure;
- printing a second metallic material, which is less anodic than the first metallic material, on the substrate as a target structure, in contact with the support structure;
- and
- chemically removing the support structure from the target structure by applying a galvanic effect to selectively corrode the first metallic material.
1 more element
Fabrication apparatus, comprising:
- a printing station, which is configured to print a first metallic material on a substrate as a support structure, and to print a second metallic material, which is less anodic than the first metallic material, on the substrate as a target structure, in contact with the support structure;
- and
- an etching station, which is configured to chemically remove the support structure from the target structure by applying a galvanic effect to selectively corrode the first metallic material.
