Abstract

Methods and systems are described for fabricating a component using 3D printing. A 3D printed piece is created including a body of the component, a support structure, and a first sacrificial interface region coupling the body of the component to the support structure. The body of the component is formed of a first metal or ceramic material and the first sacrificial interface region is formed at least partially of a second metal or ceramic material. The body of the component is then separated from the support structure by applying a chemical or electrochemical dissolution process to the 3D printed piece. Because the second metal or ceramic material is less resistant to the dissolution process than the first metal or ceramic material, the first sacrificial interface region at least partially dissolves, thereby separating the body of the metal component from the support structure, without dissolving the body of the component.
