Title:
３Ｄ金属印刷プロセスで使用するためのレーザ誘起プラズマチャネルを介した電気パルスの適用
Document Type and Number:
Japanese Patent JP6718939
Kind Code:
B2
Abstract:
A method of fabricating an object by additive manufacturing is provided. The method includes irradiating a portion of powder in a powder bed, the irradiation creating an ion channel extending to the powder. The method also includes applying electrical energy to the ion channel, wherein the electrical energy is transmitted through the ion channel to the powder in the powder bed, and energy from the irradiation and the electrical energy each contribute to melting or sintering the portion of the powder in the powder bed.
