A material modification module is suitable for a powder material. The material modification module comprises a storage barrel for storing the powder material, a screw pipe connecting the storage barrel, an air flow device providing air flow to the screw pipe and making the powder material entering the screw pipe move along the extension direction of the screw pipe, and a plasma generating device. The plasma generating device includes a first plasma generating unit for generating plasma in the screw pipe to modify the powder passing through the screw pipe.一種材料改質模組，適用於一粉料，該材料改質模組包含一儲放該粉料的儲料桶、一連通該儲料桶的螺管、一提供氣流送入該螺管並使進入該螺管之粉料沿該螺管延伸方向行進的氣流裝置，以及一電漿產生裝置。該電漿產生裝置包括一第一電漿產生單元，用以使該螺管內產生電漿對通過該螺管之粉料進行改質。
