Obesity is a complex disease affecting 23% of the Canadian population, or over 8 million people. Bariatric surgery is a common technique of treating obesity. The most popular surgical technique, called gastric sleeve surgery, involves cutting the stomach and removing 70 to 80% of its total volume. Presently, it is difficult for physicians to clearly explain this operation to their patients because of its great complexity. This paper presents a new approach that aims to improve the effectiveness of physician-patient discussions. The approach is based on the latest additive manufacturing technologies used for 3D printing of an actual size human stomach, in a material mimicking its mechanical behaviour. Two manufacturing methods are analyzed and discussed. At present, the indirect method of making a mold by additive manufacturing and pouring a flexible material inside the mold to obtain a physical stomach model is best suited for this type of application.
