Abstract
A plasticizing device includes a first member having a groove portion that has a spiral shape extending to a center, a motor that rotates the first member, a second member that faces the first member, and a heating unit for heating a material that is transported along the groove portion, the first member having a plurality of recessed portions on a bottom surface of the groove portion. By providing a plurality of recessed portions on the bottom surface of the first member through which the material flows, the rotational force of the rotating first member is easily transmitted to the material and the amount of material flowing in the first member can be increased.
