Typical Geometric Shape Features Fabricated Through Laser Powder Bed Fusion

Although there are many types and shapes of mechanical parts, the basic constituent features of mechanical parts are faces, columns, holes, angles, spheres, gaps, etc., as shown in Fig. 8.1. These features can represent the basic elements of the parts. The key factors of whether the laser powder bed fusion (L-PBF) technology can form mechanical parts can be reflected by these typical structural features. By manufacturing various typical geometric features such as thin plates, sharp corners, cylinders, round holes, square holes, spheres and gaps in Fig. 8.2, the processing capability of L-PBF was investigated in this section.
