Impact score: 32
A University of Washington team published a study in Materials (October 29): Using in-situ optical tomography on an EOS M290, they quantified the spatial distribution of spatter during laser powder bed fusion of Ti6Al4V—spatter volume in the upwind region was significantly higher than in the downwind region, gas-atomized powder produced more spatter than plasma-atomized powder, and high-spatter areas were positively correlated with the risk of lack-of-fusion defects.

华盛顿大学揭示LPBF钛合金飞溅空间分布规律（MDPI Materials）
华盛顿大学团队在《Materials》（10月29日）发表研究：基于EOS M290原位光学断层成像，量化Ti6Al4V激光粉末床熔融飞溅的空间分布——上风区飞溅体积显著高于下风区，气雾化粉末比等离子雾化粉末飞溅更多，高飞溅区与未熔合缺陷风险正相关。
