Cover Story: The generation of a good-quality digital anatomical model of the heart is a complex task. Its 3D representation, however, has the potential to provide detailed spatial information concerning the heart’s structure, also offering new opportunities if combined with additive manufacturing. In this work, we illustrate the difficulties that may be encountered in the workflow from a stack of computed tomography (CT) to the handheld printed heart model, which also considers real wall thickness variability. Stereolithography printing technology is exploited, and the accuracy of the result evaluated. View this paper
