a A real size AM part analyzed for heat accumulation. b Maximum temperature attained for each nodal point as an indicator of overheating. The thermal history is obtained using a layer-by-layer gradual heating model and it shows that gradual heating can qualitatively capture influence of geometric features on thermal history. c Visualization of optical tomography (OT) data recorded during part fabrication, the funnel shapes are identified as the cause of heat accumulation where high OT values are seen. These results are reproduced from [52] where further details can be found
