  1. The simulation results suggest that, at the end of the scanning line, the dissymmetric temperature field and the great temperature gradient result in the balling phenomenon and great thermal stress, which could lead to the destruction of the sintering samples in this region. because of the coupling effect between scanning lines, the balling phenomenon is increased as the increase of the scanning lines, thus the over short scanning lines should be avoided in the sintering process. different scanning strategies have significant influence on the sintering

    模擬結果表明，掃描端點溫度場的不對稱及較大的溫度梯度造成了端點球化現象，並在端點處產生較大的熱應力，使燒結成形試樣易在此處破壞;激光掃描線間的耦合作用使端點球化現象隨掃描線的增加而逐漸顯著，燒結時應避免過短的掃描線;不同掃描策略對燒結成形有很大影響，交替掃描會影響燒結試樣的質量，實際製造時應採用單向掃描策略。
