| Summary: | In this study, the microstructure of open-cell metal foam
was generated and reconstructed, to produce a new
generation of open-cell foam, which is called 3D printed
open-cell foam. At the current stage of research, nylon
powder and plastic acid are utilized as the materials for
two different 3D printing technologies: Selective Laser
Sintering (SLS) and Fused Deposition Modelling (FDM),
respectively. The microstructural properties and surface
roughness of the 3D printed open-cell foam are
investigated using CAD files and microscope images. The
surface smoothness and structure strength are found to be
dependent on the printing technologies, material
employed, and foam size. However, the SLS technology
produced smoother ligament surfaces with fewer residues
than using the FDM. The ligaments of the small-size 3D
printed open-cell foam at the exact size of the metallic
foam, on the other hand, are weak and easily shattered.
This study also found that the trends of pressure drop
from additive manufacturing methods agreed to the
original metallic open-cell foam, which are decreasing
with the increase of pore sizes. |
