Neuroengineering related interventions to small
animals always carry the high risk of missled procedures,
frequently causing premature death of the animal. In this
paper the manufacturing process to build a physical rat skull
and brain model for educational use is presented. Out of
MRI images a rat brain was segmented to build a negative
mould. This form was used to cast an agarose rat brain. For
an accompanying rat neurocranium model, CT images were
rendered to a surface mesh and printed in 3D out of PLA. The
presented workflow results in a high detailed rat skull and rat
brain.
