Cerebral Vascular Territories Model

The brain receives blood from several major arteries. Understanding which parts of the brain receive blood from which arteries is very helpful in clinical neurology. This model helps teaching and learning 3d cerebrovascular anatomy.

This model requires a color-changing printer with capacity for 7 filaments. I printed it on a Bambu X1C connected to two AMS units. The color painting was done in BambuStudio and unfortunately does not translate to other slicers. Someday, I will try to create a version requiring only 5 filaments for any one print, and I will try to repaint it in Prusaslicer.

Assembly:

Attach the screws, washers, and nuts to the base but do not tighten fully. Slide the brain slices over the screws, then tighten fully. There is one piece which must be glued after printing (the small piece named “cerebellum 60+”), which can be superglued to the top of the cerebellum (glued to slice “47-60 w hypothalamus”)

Necessary non-printed materials listed below: 

• Hex Head Screw 1/4"-20 Thread Size, 5" Long, Fully Threaded x 2: https://www.mcmaster.com/91309A562/
• Hex Nut, 1/4"-20 Thread Size x 2: https://www.mcmaster.com/90473A029/
• Split Lock Washer for 1/4" Screw Size, 0.26" ID, 0.487" OD x 2: https://www.mcmaster.com/91101A229/
• Hex Head Screws, 6-32 Thread Size, 1-1/2" Long x 1: https://www.mcmaster.com/catalog/130/3566/93075A546
• Hex Nut, 6-32 Thread Size x 1: https://www.mcmaster.com/90480A007/
• Split Lock Washer for Number 6 Screw Size, 0.148" ID, 0.25" OD x 1: https://www.mcmaster.com/91102A730/

Key:

Red = MCA (middle cerebral artery)

Yellow = ACA (anterior cerebral artery)

Blue = PCA (posterior cerebral artery)

Orange = ML (medial lenticulostriate arteries)

Magenta = LL (lateral lenticulostriate arteries)

Pink = AC (anterior choroidal artery)

Green = basilar artery and pontine perforators

Light blue = AICA (anterior inferior cerebellar artery)

Seafoam blue = SCA (superior cerebellar artery)

Dark Purple = PICA (posterior inferior cerebellar artery)

Brown = ASA (anterior spinal artery)

Yellow-green = PSA (posterior spinal artery)
