Meshlab Ambient Occlusion for Hollowing

Here is another tutorial on hollowing meshes, specifically head meshes to obtain a face shell, but I use this method to hollow out bones as well.   Dr. Mike recently posted a great video tutorial on hollowing a head using Meshmixer: https://www.embodi3d.com/blogs/entry/359-how-to-create-a-hollow-shell-from-a-medical-stl-file-using-meshmixer/.   I tend to go back and forth between Meshmixer and Meshlab for different functions to prep a print, but I like to use Meshlab for holl

Modeling Pubic Bones for 3D Printing Pt. 1: Grayscale Model Maker in Slicer

Here is a tutorial for the Grayscale Model Maker in the free program Slicer, specifically for modeling pubic bones since they are used in anthropology for age and sex estimation. The Grayscale Model Maker is very quick and easy!   And I can't stand the "flashing" in the Editor.   For this example, I am using a scan from TCIA, specifically from the CT Lymph Node collection.   Slicer Functions used: Load Data/Load DICOM Volume Rendering Crop Volum

Why do anthropologists need 3D printed bones?

I thought I'd do a quick post on why anthropologists need 3D printed bones in case anybody's interested.   Real bones are expensive! Although we have real skeletons for teaching osteology, we are often limited to teaching the identification and examination of whole bones. For both forensic and archaeological contexts, osteologists need to be able to identify bones that are incomplete, scavenged, weathered, burned, or damaged in some other way. In such situations, the first question is
