About this 3D model

This is the front part of the Skull of an around thirty year old man. FOSS - Slicer http://www.slicer.org/ was used to convert the CT data into an rudimentary *.stl of 523MB size. This tutorial video helped a lot: https://www.youtube.com/watch?v=og3t1i9gSG0 Then Meshlab: * check on holes * removal of unconnected parts * smoothing and downsampling to 130MB It might be printable as it is with an SLS-Nylon printer but the natural stucture is rather fine (thinn walls) in relation to the models size. Thus for an FDM Printer I guess further modification will be necessary. Either unrealistic simplification for a smaller print, or scale-up and splitup into multiple parts.
