Creating a breakaway region

An apparatus is disclosed to create a breakaway junction for 3D printed parts. Powder is spread along a target zone, such as a build bed. A liquid functional agent is selectively dispensed upon the powder to form a 3D object, a supporting part, and the breakaway junction between them.
