This STL file of the pelvis and sacrum is ready for medical 3D printing. The ilium, ischium, pubis, and sacrum bones are part of the resulting model when the STL file is 3D printed. The file is derived from a human CT scan DICOM file which was converted from medical image to an STL file using democratiz3D the NRRD to STL file converter available at embodi3D. After converting this pelvic bone file it was first available on embodi3D.com as part of a large 3D biomedical model collection.
