PBF-LB/M Ti6Al4V micrographs and labeled manufacturing defects

<strong>Desciption:</strong> This dataset contains 775 micrographs of laser additive manufactured Ti6Al4V. Further the dataset contains 1200 labeled binary images of defects classified in lack of fusion (400), keyhole (400) and process pores (400). Additional local extracted features are added as csv File. To all of the 757 micrographs are the process parameter combinations included, also for those which couldn´t be built. The process parameters were created randomly and equally distributed in between limits. The layer thicknesses included are 25 µm, 50 µm, 75 µm and 100 µm. Further the laser power, the hatch distance and the scan speed were changed. The build platform temperature was set to 200 °C. All specimens were printed an a SLM 125 HL by SLM Solutions with CL 41 Ti ELI powder by Concept Laser. <strong>Author Contributions: </strong>Conceptualisation S.M., M.L.A., L.M., A.T.; methodology for (randomised) test series: M.L.A., L.M., S.M.; data creation, printing and imaging: L.M., S.M., T.B.; defect data labeling: M.L.A., T.B.; defect feature extraction: M.L.A.; supervision: A.T.; funding acqusition : A.T. <strong>Funding: </strong>This work is funded by the University of Bremen Research Alliance (UBRA) AI Center for Healthcare within the project ENABLE.<strong>数据集描述:</strong> 本数据集包含775张激光增材制造Ti6Al4V合金的显微照片。此外，数据集还包含1200张带标注的二值化缺陷图像，缺陷分为三类：熔合不足（400张）、匙孔缺陷（400张）与工艺气孔（400张）。额外提取的局部特征以CSV文件形式提供。所有757张显微照片均附带对应的工艺参数组合信息，即使是那些无法成型的试样也包含对应参数。工艺参数均为随机生成且在限值范围内均匀分布，涉及的层厚参数包括25μm、50μm、75μm与100μm，同时还调整了激光功率、扫描 hatch 间距（hatch distance）与扫描速度。成形平台温度设定为200℃。所有试样均由SLM Solutions公司的SLM 125 HL设备，采用Concept Laser公司的CL 41 Ti ELI合金粉末打印成型。<strong>作者贡献:</strong> 概念设计：S.M.、M.L.A.、L.M.、A.T.；随机化试验系列方法学：M.L.A.、L.M.、S.M.；数据制作、试样打印与图像采集：L.M.、S.M.、T.B.；缺陷数据标注：M.L.A.、T.B.；缺陷特征提取：M.L.A.；项目指导：A.T.；项目经费获取：A.T.<strong>资助信息:</strong> 本研究受到不来梅大学研究联盟（UBRA）医疗人工智能中心下属ENABLE项目的资助。
