Preoperative rehearsal is very important before the operation, because of its particularity and difficulty, traditional printing can hardly achieve it, and thus a new kind of fixture for the 3D printing of pelvis model is critical. Fixture design in manufacturing system is very important and directly affects the processing quality, production efficiency and manufacturing costs. As a new method of manufacturing, the alternative style of additive and subtractive manufacturing is potential in market prospect. New requirements on the performance and structure of the fixture were put forward due to the high complexity of product surface in alternative manufacturing, as well as the force characteristics of numerical control (NC) processing. In this paper, we propose a novel type of fixture which is capable of completing printing tasks in preoperative rehearsal. An experiment is performed to validate the rationality and universality of the fixture. A 3D printing practical case of pelvis model before pelvic correction surgery is used to demonstrate the effectiveness of the present fixture. [ABSTRACT FROM AUTHOR]
