Description
従って、本発明の目的は、粉体床を得ること、並びに固化する前にこの粉体床を分析することを可能にする装置を提供することである。
従って、堆積モジュールの移動に追従するプローブによってスキャンすることができる全領域に対する情報が得られる。ストリップは、使用する電磁応答プローブが分析できる部分の幅に対応する幅を有する。
従って、2度の分析で、粉体床のストリップの良好な分析を得ることができる。
例えば、1度のスキャンで粉体床の全てをカバーして分析するために、複数の一定の間隔で配置されたプローブを導入することができる。
従って、プローブ又は複数のプローブから提供された情報は、粉体床の溶解を適応させるために考慮することができる。特に、密度又は均質性の変動は、溶解時間を適応させるために考慮することができる。従って、良好な焼結、又は良好な選択的レーザ溶解を得ることができ、このことは特に品質の優れた物品をもたらすことができる。
磁場の測定は、電磁応答プローブを用いて行うことができる。
粉体床のストリップは、表面のスキャン中に分析することができる。
異なる粉体床供給部分を同時に分析することができる。
例えば、電磁応答プローブの使用に適している鉄又は任意の他の材料を含む、磁性粉体の使用が好ましいことに留意されたい。
各プローブ5は、粉体床の一部分6を分析することができる。図2から分かるように、プローブは、複数の隣接する各部分6をカバーするために一定の間隔で配置することができる。プローブ5の数を増やすことで、横断ストリップをカバーすることが可能になり、粉体床の全ては、アーム3が行うスキャン中に分析することができる。
粉体床部分、粉体床ストリップ、又は粉体床全体を分析した後、この分析で得られた、例えば、粉体床の密度又は均質性に関するデータは、プロセッサ11で処理される。
機械10は、堆積された粉体床の少なくとも一部分を固化するための固化手段12を備える。例示的に、固化手段は、レーザービーム装置を備えることができる。
この分析で得られた情報により、後続の焼結又は選択的レーザ溶解ステップを改善することができ、これによって良好な固化を行うことが可能になる。
