| Abstract Scope |
Real-time control through the use of sensors and controllers is being applied in powder bed fusion AM systems to manage in-situ process features like melt pool size and temperature. Despite this technology, geometry deviation and surface roughness defects still persist due to difficulty of obtaining accurate geometric information during the build. Although in-situ monitoring captures several in-process data, precise geometric information is challenging to acquire. To address this problem, a statistical approach is proposed to predict material formation in 3D, particularly the geometry of overhang surface using process parameters and coaxial melt pool images. The preliminary results from an experiment involving four overhang parts, with 100,000 melt pool images generated, indicate that the proposed method provides a solution for real-time control of part geometry and surface roughness. This presentation would present the findings of overhang dross depth, related melt pool features, and their statistical correlations. |
