Abstract
Description
電子ビームの粉末床溶融に基づく付加製造において、粉末床における過剰な電荷の形成を回避するように設計された予め定められたパターンで、粉末床に対して電子ビームスポットを走査することによって、新たな粉末層の各々を予熱することが可能となる。ビーム走査スピードは、粉末が部分的焼結するが融解しない温度まで粉末のみが加熱されるように、十分に高くなければならない。予熱走査パターンは、粉末床が部分的焼結状態に到達するために必要な場合には、複数回繰り返されてよい。ひとたび粉末床が部分的焼結されると、電子ビームは、帯電した粉末が浮揚および散乱するリスクなしに、粉末層の融解を開始してよい。
