3D Printed Superior Orbit ModelThis 3D printed model captures a dissection in which the calvaria and cerebrum have been removed to expose the floors of the anterior and middle cranial fossae.
The midbrain has been sectioned at the level of the tentorium cerebelli and on the cross sectional surface one can identify the superior colliculi, cerebral peduncles and the substantia nigra. Anterior to the mid-brain the vertebral artery can be clearly identified rising from the posterior cranial fossa and dividing into the posterior cerebral arteries.
Anterior to this in the region of the sella turcica one can identify the internal carotid arteries emerging from the roof of the cavernous sinus medial to the anterior clinoid processes and beneath and lateral to the optic nerves and chiasm. The oculomotor nerves are visible penetrating the roof of the cavernous sinuses on the left and right posterior to the point where the internal carotid arteries emerge.
Anteriorly in the midline of the anterior cranial fossa lies the crista galli with the olfactory bulbs still present above the cribriform plates on either side. On the right the orbital plate of the frontal bone (the roof of the orbit) has been removed to expose the frontal nerve splitting into the supraorbital and supratrochlear nerves lying superior to the levator palpebrae superioris.
The trochlear nerve is visible entering the superior aspect of the superior oblique muscle belly on the medial aspect of the orbit. Ethmoidal air cells have been exposed in the medial orbital wall by removal of the part of the lamina papyracea. On the left the levator palpebrae and superior rectus muscles have been divided along with the frontal nerve to expose the optic nerve, nasociliary nerve, ophthalmic artery and superior ophthalmic vein in the intraconal space.
The face has been dissected to show facial muscles around the orbit on the right and the infraorbital nerve on the left. The infratrochlear nerve is also shown on the right and facial veins and arteries are also visible.

The models are very detailed and delicate. With normal production machines you cannot realize such details like shown in these models.
The printer used is a color-plastic printer. This is the most suitable printer for these models.
The plastic material is already the best and most suitable material for these prints. (The other option would be a kind of gypsum, but this is way more fragile. You even cannot get them out of the printer without breaking them).The huge advantage of the prints is that they are very realistic as the data is coming from real human specimen. Nothing is shaped or stylized.
The users have to handle these prints with utmost care. They are not made for touching or bending any thin nerves, arteries, vessels etc. The 3D printed models should sit on a table and just rotated at the table.
