Parametric study of surface morphology for selective laser melting on Ti6Al4V powder bed with numerical and experimental methods
A three-dimensional (3D) selective laser melting (SLM) model comprising coupled heat transfer and flow behavior is proposed. The free surface of the melt pool is calculated by the volume-of-fluid (VOF) method,...

Support structure design in additive manufacturing based on topology optimization
A support structure design technique for additive manufacturing (AM) is proposed that minimizes the deformation while using the least amount of support material, minimizes the time required to add the supports...
