Generation of the original STL file (source STL). (A): With the Mimics Innovation Suite (MIS) software package, the blood volume (aorta and iliac bifurcation, fuchsia) was segmented from the original DICOM dataset (resolution 1 mm) and transformed into an STL file. (B): The STL file of the blood volume was then imported into the 3Matic module of MIS. (C): Using the “hollow” tool, a wall thickness of 2 mm was applied externally to the aorta. (D): Finally, the ostia were opened using the “trim” tool and the part of interest (abdominal aorta) of the model was exported as an STL file.
