Print head for additive manufacturing system

An additive manufacturing system, comprising:

• a support;
• and
• a print head moveable by the support in a normal travel direction parallel to a print surface during discharge of material from the print head onto the print surface, the print head including:
• a mount connected to the support;
• an outlet through which the material is discharged, the outlet having an axis that is oriented at an angle of about 30-60° relative to the normal travel direction;
• an outlet actuator operatively connected between the mount and the outlet and configured to selectively translate the outlet along the axis;
• and
• a compactor disposed downstream of the outlet relative to the normal travel direction and configured to press the material in a compaction direction against the print surface, wherein:
• the compaction direction is orthogonal to the normal travel direction;
• the print head has an axis of rotation at an end of the support;
• and
• the compaction direction is parallel with the axis of rotation.

A method of additively manufacturing a composite structure, comprising:

• moving a print head in a normal travel direction parallel to a print surface;
• discharging material through an outlet of the print head during movement in the normal travel direction, the outlet having a discharge axis that is oriented at an oblique angle relative to the normal travel direction;
• and
• selectively translating the outlet along the discharge axis relative to a support mount of the print head.
