The 3D printed models of the patient's anatomy. (a) Multiple part version of the anatomical model. Components included are the spinal column (yellow), tumor mass (green), carotid artery (red), and jugular vein (blue). (b) Low-cost model excluding the tumor volume and local vasculature. (c) Replica of the previously implanted hardware.

The Netherlands). The multi-material model was used to represent the volume of the tumor, the spine, and local vasculature in different colors and cost roughly US$300, while the low-cost model was used to recreate the cervical spine as well as the surgical hardware that was implanted previously and cost roughly US$5 (Figure 2).
