    • A heating tool for shaping a soft material is provided. The heating tool is mounted to a predetermined position of a shaping apparatus and connected to a power source provided at a predetermined position of the shaping apparatus to melt and shape the soft material under a high temperature. The heating tool includes shaping parts which come in contact with the soft material to melt the soft material, and heating parts which are provided to be in non-contact with the soft material. The heating parts collect the molten soft material and thermally decompose the molten soft material. The heating tool enables a surface of the soft material to be perfectly thermally decomposed. Thus, the present invention prevents the soft material from being undesirably deformed, due to the molten material remaining after a shaping process.
