Whole process of three‐dimensional (3D) printing. CT scan obtained from the patients should be saved as digital imaging and communications in medicine (DICOM) format and imported into DICOM‐compatible software to conduct thresholding and segmentation of anatomy of interest. Then, the file should be saved in stereolithographic (.STL) format to be communicated to the STL‐compatible postprocessing software for further mesh editing, cleaning, healing, and smoothing. We can also design custom prostheses or patient‐specific instruments (PSI) for virtual surgical planning if necessary. Finally, the. STL file is imported into a 3D printer to result in the formation of 3D structures.
