The authors evaluated fused deposition modeling for the production of aneurysm models replicating patient-specific anatomy using 3D rotational angiographic data from 10 patients. A hollow model with connectors for silicone tubes was fabricated by using acrylonitrile butadiene styrene, the support material was then dissolved, and the surfaces finished by using NanoSeal. The models were filled with iodinated contrast and 3D rotational angiography was performed. Reproduction of hollow aneurysm models was technically feasible in 8 of 10 cases, and a high level of anatomic accuracy was observed.
