Comparison between compression tested and simulated Mg-6.3Gd bone scaffolds produced by binder based additive manufacturing technique

Abstract

In this study, a binder based 3D-printing technology viz. Fused Granular Fabrication (FGF) technique was used to produce interconnected and open porous Mg-6.3Gd bone scaffolds for compression test analyses. The consolidation of the green parts (as printed scaffolds) was performed using solvent debinding in cyclohexane and subsequent conventional sintering in argon atmosphere. Compression tests were performed on as sintered parts. Additionally, a simulation strategy was developed for modeling the compression behavior of the sintered parts, utilizing the data from the experimental results. The experimental compression test results and the simulation strategy for the compression behavior of the 3D-printed scaffolds demonstrated good agreement.
