Description
本發明係與積層製造技術有關，特別係指一種可改善積層製造加工腔體內部流場配置之積層製造腔體。 The present invention relates to laminated manufacturing technology, and particularly relates to a laminated manufacturing cavity capable of improving the flow field configuration inside the laminated manufacturing cavity.
PBF(粉床熔融成形)技術為在一平面上鋪放薄層粉末材料後，以雷射光束將粉末燒結/融化形成熔融池(Melting Pool)，熔融池依序冷凝固化進而完成所要成型的單層外型，經過不斷地鋪粉、燒結/燒融、平面下降、再鋪粉的程序後逐步堆疊出最終工件成品。早期PBF技術(如EOS M270)並未於加工腔體內對進排氣流場進行設計，粉末受熱後將導致部分材料氣化形成粉塵，並隨機分布於加工腔體內，此時雷射需額外穿透腔體內部環境中之粉末、致使雷射能量利用效率降低。此外環境中之粉塵將於製造過程中累積於工件表面，使工件表面更為粗糙、進而降低工件品質。 PBF (Powder Bed Melting and Forming) technology is to lay out a thin layer of powder material on a plane, and then sinter / melt the powder with a laser beam to form a melting pool. The melting pool condenses and solidifies in order to complete the unit to be formed. The appearance of the layer, after continuous powdering, sintering / firing, plane lowering, and then powdering, the final workpiece is gradually stacked. The early PBF technology (such as EOS M270) did not design the inlet and exhaust flow fields in the processing cavity. After the powder is heated, some materials will be vaporized to form dust and randomly distributed in the processing cavity. At this time, the laser needs to pass through Through the powder in the internal environment of the cavity, the laser energy utilization efficiency is reduced. In addition, the dust in the environment will accumulate on the surface of the workpiece during the manufacturing process, making the surface of the workpiece rougher, thereby reducing the quality of the workpiece.

As shown, the airflow flow fields formed by the multiple air inlets on the same side will interfere with each other, forming multiple recirculation structures inside the processing cavity, and even forming a downward vertical flow field above the processing plane. Unable to form a uniform flow field in the same direction in the processing surface, which causes powder to be easily deposited at multiple reflow points inside the processing cavity, which affects the processing quality, and increases the difficulty and time and labor cost of cleaning the cavity.
