N2 - The limited amount of human tissue donors makes itorganizationally hard to investigate the biomechanicalbehavior of human femoral bones. To circumvent theproblem, artificial bones are often used [1]. Currently abroad range of different casted artificial bones arecommercially available, ranging from polyurethanebasedfoam models to more complex compositematerials. However, these models are only genericrepresentations of the geometry and the biomechanicalbehavior of human bones. In previous studies, fuseddeposition modelling (FDM) was successfully used tomimic natural bones [2]. The aim of this study was touse 3D printing for the fabrication of artificial humanfemoral bones with biomechanical behavior resemblingthat of their real counterparts. One group of samples isbased on the geometry and infill properties ofcommercial artificial femurs to validate and optimizethe process. For the second group, patient specificcomputed tomography scans (CT-scans) were used forthe geometry. All printed bones are then mechanicallytested and compared to their geometrical analoguecommercial and human donor bone.
