Abstract: A system for depositing a material includes a die and a flow guide. The die includes an opening and a cavity communicating with the opening. The die is configured to extrude the material in a principal deposition direction through the opening. The flow guide is disposed in the cavity and is configured to shape a flow of the material extruded by the die. The flow guide includes a flow narrowing portion and a flow shaping portion. The flow narrowing portion extends in a width direction perpendicular to the principal deposition direction so as to block the material from flowing through in the principal deposition direction. The flow shaping portion extends downstream from the flow narrowing portion in the principal deposition direction. A width of the flow shaping portion is smaller than, or decreases from, a width of the flow narrowing portion.
