Additive manufactured object with self-breaking support with fluid passage

摘要

An object includes a fluid chamber extending between a first surface and a vertically opposed second surface, the first surface including a fluid passage opening therethrough. A self-breaking support, initially configured to support the first surface, once broken creates a broken support disposed between the first surface and the vertically opposed second surface. The support includes: a base having a first end coupled to the first surface and a second opposing end. The first end of the base is wider than the second end, and a fluid passage extends through the first base for fluidly coupling the fluid chamber and the fluid passage opening in the first surface. A self-breaking link is disposed between the second opposing end of the first base and the second surface.
