Description
ここで、ガス噴射装置により焼結体の側面近傍に吹き付けられるガスの強さが強すぎると、吹きつけたガスの勢いで材料粉末が舞い上がり造形環境が悪化してしまう。本発明では、ガス噴射装置によるガス噴射の強さは、材料粉末が舞い上がらない範囲内である。従って、ガスによって吹き飛ばされる材料粉末を舞い上がらせることなく、焼結体の側面近傍の材料粉末を吹き飛ばすことができる。これにより、良好な造形環境を保持しつつ、焼結体の側面近傍から材料粉末を除去することができる。
本実施形態では、ガス噴射装置10による間欠噴射によって、焼結体21の小さな穴21aや細い溝21b,21cの中に詰まった材料粉末を除去する。これにより、穴21aや溝21b,21cの中の材料粉末を上側から順に少しずつ浮かせて外側に吹き飛ばし、中に詰まった材料粉末を除去することができる。以上により、穴21aや溝21b,21cの中に切削工具9の切刃9Aが入り込む空間S2〜S4を形成することができるため、焼結体21の側面切削の際に切削工具9の切刃9Aに材料粉末が噛み込みこむことを防止できる。これにより、切削工具9の切刃9Aが損傷することを防止できる。
