Using a 3D printer, our research team has synthesized medical image data, including CT, MRI, and DSA images, to create 3D models, which are applied to operative simulations. The present paper summarizes the following methods for their creation and presents clinical examples: The positions of CT, MRI, and 3D-DSA images are first set, using 3D image analysis computer software, and their format is converted from DICOM data to the STL file format. The above-mentioned 3D models are created by powder-based 3D printing. The powder-based 3D printer allows users to create full-color, high-resolution models in a short time, effectively examine operative approaches, and understand the spatial position of a tumor relative to the surrounding vessels. On the other hand, the equipment has the disadvantage of being expensive, which needs to be addressed.
