Additive Manufacturing of Cranial Simulants for Blast Induced Traumatic Brain Injury

Abstract

The widespread use of Improvised explosive devices (IEDs) in warfare has resulted in devastating injuries to United States military personnel, with blast induced traumatic brain Injury (TBI) a possible outcome. Blast TBI results in significant damage to intracranial vasculature and tissue interfaces, presumably because of relatively sharp changes in mechanical properties at boundaries between different materials. Nevertheless, understanding of this damage mechanism is largely lacking, limiting early detection and prevention efforts. The purpose of this study Is to produce models of the human head with materials that simulate the mechanical properties of the skull and its contents. In particular, we seek to simulate interfaces between CSF-brain, gray-white, and vasculature-brain.
