Abstract Scope |
The stability of the melt pool in Laser Powder Bed Fusion (L-PBF), especially with process perturbations, is a key factor underpinning the success of a build. In metal Additive Manufacturing, single tracks are widely used to verify and validate simulation and process models. This work describes the creation of a holistic L-PBF single track data set incorporating a large domain of process conditions for AlSi10Mg. The 352 single tracks are characterized through a series of high throughput methods including white light interferometry, automated microstructure analysis, and in-situ high-frequency (up to 200 kHz) coaxial melt pool monitoring. This data constitutes a large database of process parameters, high-resolution measurements, and geometry information for data driven analysis, including machine learning. In one approach this data is used to correlate track shape and melt pool characteristics to in-situ measurements. |
