CoRR, 2022 A Matlab-based computational procedure is proposed to fill a given volume with spheres whose radii are randomly picked from any specified probability distribution supported by \verb|Matlab|. The general program sequence and examples of filling a unit cube, a parallelepiped, and a concave domain between two hemispherical surfaces, with spheres whose ...

, 2023 AbstractPowder bed laser 3D printing performed using polar coordinates, called Spiral Growth Manufacturing (SGM), allows manufacturing axisymmetric revolution parts in less time compared to conventional cartesian laser printing or Selective Laser Melting (SLM). In this work, a device to perform SGM operating under polar coordinates is presented.
