PROBLEM TO BE SOLVED: To provide a powder feed system capable of realizing shortening of a manufacturing time and reduction of manufacturing cost without causing increase of facility cost and an installation space. SOLUTION: The powder feed system 10 has a plurality of cassettes 12A-D constituted by flexible containers 16A-D; and a plurality of bases 20A-D for retaining the flexible containers 16A-D respectively. Further, the powder feed system 10 has a conveying part 14 for conveying the cassettes 12A-D. The base 20 has a powder discharge passage communicated with a discharge port of the flexible container 16; and an opening/closing valve for opening/closing the powder discharge passage. Thereby, even if all powder in the flexible container are not released, exchange of the flexible container can be carried out and shortening of the manufacturing time and reduction of the manufacturing cost can be realized.
