Abstract Scope |
Porosity in additively manufactured parts hinder the component's fatigue life and prevent its use in design critical areas and Machine Learning (ML) can help predict and prevent these defects. In-situ melt pool thermal image processing mapped to ex-situ porosity can improve production yield and minimize costs through waste reduction. This work shows a Swin Transformer fine-tuned on a thermal image dataset obtained using a two color pyrometry camera to map to Computed Tomography (CT) generated voxel space porosity. The dataset includes an input and label set of varying processing conditions which the model uses to generate its porosity predictions. This model displayed high accuracy in downstream prediction tasks such as layer-wise porosity classifications and volumetric porosity fractions from the processed input of thermal images. Furthermore, mapping of two-dimensional thermal images to a three-dimensional reconstruction of the sample and its corresponding porosity was investigated as well. |
