Zusammenfassung:To provide a magnet manufacturing device capable of manufacturing magnets whose shape and magnetization direction are arbitrarily designed.SOLUTION: A magnet manufacturing device includes: a heater 12 which heats a mixture 23 of magnetic particles and a resin material; a nozzle 13 which has an internal flow passage where the mixture 23 flows while the resin material is molten and which has a discharge port 132 discharging the mixture to form a yarn-shaped filament 24; a magnetic field application magnet 15 which has a size enabling the orientation and magnetization of the magnetic particles, and which applies, to the internal flow passage of the nozzle 13, a magnetic field directed in the axial direction of the nozzle; and a stage 14 which has a stage surface 141 on which the filament 24 is placed. The discharge port 132 is relatively movable with respect to the stage surface 141 in any direction in three dimensions such that a plurality of the filaments 24 are stacked to form an arbitrary shape and an extending direction of each of the filaments 24 corresponds to a target magnetization direction.SELECTED DRAWING: Figure 1 【課題】磁石の形状と磁化方向とが任意に設計された磁石を製造することができる磁石製造装置を提供する。【解決手段】磁石製造装置は、磁粉と樹脂材料の混合物23を加熱するヒータ12と、樹脂材料が融解した状態の混合物23が流れる内部流路を有するとともに、混合物を吐出して糸形状のフィラメント24を形成する吐出口132を有するノズル13と、磁粉の配向と着磁が可能な大きさであって、ノズルの軸線方向に沿う向きである磁場を、ノズル13の内部流路に対して印加する磁場印加磁石15と、フィラメント24が配置されるステージ面141を有するステージ14と、を備える。複数のフィラメント24が積み重なって任意の形状をなすとともに、各フィラメント24の向きが目標の磁化方向に対応する向きになるように、吐出口132がステージ面141に対して三次元の任意方向に相対的に移動する。【選択図】図1
