Abstract
An injection mold cavity and a method for fabricating an injection mold cavity. The mold cavity includes a tear-drop shaped channel and an ejection valve simultaneously formed with the fabrication of the mold cavity using a layer-additive process. The ejection valve is movable within the mold cavity and actuatable by a flow of gas through the channel to eject a molded part from the injection mold cavity. The mold cavity, including the ejection valve, is made of the same material.
