Abstract

An apparatus for additively manufacturing a heterogeneous structure (50) using a plastic fiber (10) and an energy transfer material (20) is disclosed. Additive manufacturing is performed in a vertical direction (z) perpendicular to a horizontal plane (x-y). The apparatus comprises: a nozzle device (110) adapted to provide the plastic fiber (10) for additive manufacturing; a feeding device (120) adapted to move the energy transfer material (20) back and forth in a vertical direction (z); and moving device (130) adapted to independently move (or rotate) the feeding device (120) and the nozzle device (110) in the horizontal plane (x-y) to fabricate the heterogeneous structure (50) in the horizontal plane (x-y).
