2.3 Post-processing
After 3D-printing, the model undergoes several post-processing (i.e.,
post-printing) steps before it is suitable for dissection. To support
overhanging structures during printing, a low-density support-structure
needs to be printed and manually removed after printing. Further,
non-bony structures such as the dura, sigmoid sinus and facial nerve are
added after printing. The dura and sigmoid sinus are represented by
applying a silicone layer mixed with either purple or blue color to the
relevant areas and the facial nerve by placing a piece of thin
electrical wire with a yellow jacket in the fallopian canal. The manual
post-processing steps take approximately five minutes per model.
