Abstract:

Additive manufacturing is gaining a significant place in Industry 4.0-driven environments, primarily due to the requirements for smoothly and quickly generatively designed components as opposed to multiple machining processes. The internal structure of the manufactured components has different geometric specifications depending on the filling density (80% to 100%) and filling pattern (lines, grid, triangles, etc.). This paper attempts to define the porosity of the additively manufactured parts depending on the infill parameters that affect the mechanical characterization of the parts using industrial computed tomography and observe the internal lattice structures and pattern-to-pore ratios of the manufactured parts.
