AI中文摘要:
我们引入了一个多模态定向能量沉积(DED)数据集,用于预测在316L不锈钢基板上产生的单个激光轨迹的概率局部几何变化。该数据集支持NSF未来制造数据挑战,包含三种互补模态:来自Stratonics ThermaViz熔池传感器的原位热图像序列、使用蔡司EVO MA10系统获取的扫描电子显微镜(SEM)图像,以及使用布鲁克ContourGT-K白光3D光学轮廓仪获取的全场高度图。每个实验是在200、300、350和400W这四种激光功率之一进行的平板上的熔覆扫描,扫描速度固定为10mm/s。此次发布包括入门笔记本、面向参与者的代码,以及一个多模态坐标约定,可在20 - 100mm的公共物理窗口上关联热、SEM和高度图测量。
英文摘要:
We introduce a multimodal directed energy deposition (DED) dataset for predicting the probabilistic local geometric variation of single laser tracks produced on stainless-steel 316L substrates. The dataset supports the NSF Future Manufacturing Data Challenge and contains three complementary modalities: in-situ thermal image sequences from a Stratonics ThermaViz melt-pool sensor, scanning electron microscopy (SEM) images acquired using a Zeiss EVO MA10 system, and full-field height maps acquired using a Bruker ContourGT-K white-light 3D optical profilometer. Each experiment is a bead-on-plate scan at one of four laser powers, 200, 300, 350, and 400 W, with a fixed scan speed of 10 mm/s. The release includes a multimodal coordinate convention linking thermal, SEM, and height-map measurements over a common physical 20--100 mm window, with the raw dataset available on Zenodo and participant-facing notebooks, reusable code, and documentation available on GitHub.
