Figure 8. The Workflow of Using 3D Printing in Surgical Applications Is Presented
First a 3D reconstruction of 2D slices is performed. In the indirect technique a model can be printed for further preoperative planning. In the direct technique computer-assisted design programs are used to design surgical guides and patient-specific implants. These aids can later be inspected using a 3D print of the 3D reconstructed tissue as in the indirect technique.
