Due to a limited availability of human bone for training purposes in ear surgery, authentic models are needed. The Magdeburg temporal bone model (Mtbm) is an epoxy resin facsimile of a human os temporale which is manufactured by 3D printing based on human computed tomography data. Here, the processing properties of the Mtbm are investigated with respect to the drilling and milling behavior and the elastic modulus. Results are compared with those of human os temporale. The forces during drilling and milling and the elastic moduli show significant differences between both types of material – all values are significantly higher for bone. However, reproducing the trabecular structure of human bone results in a similar degree of force fluctuations. Thus, an authentic feeling for the surgeon is roughly provided by the AFM.
