Abstract
Disclosed are a head unit and a head supply unit. The head unit according to the present invention discharges a raw material made of plastic formable materials. The head unit includes: a head pipe which guides the movement of the raw material; a head heater which surrounds the entire or partial head pipe and controls the temperature of the raw material which is moving within the head pipe; and a discharge port which is provided on one end of the heat pipe and discharges the raw material to the outside. The head supply unit according to the present invention includes: an inlet through which a raw material made of plastic formable materials is introduced; an inlet pipe which guides the raw material introduced through the inlet; a head supply heater which controls the temperature of the raw material which passes through the inside of the inlet pipe; and a head fastener which is fastened to a head unit which discharges the raw material. As a result, the temperature of the raw material which is easily solidified, cured or degraded is controlled, so that the raw material can be smoothly discharged and at various positions and angles. Accordingly, it is possible to manufacture a more complex and sophisticated three-dimensional product.
