The invention provides a device and method for achieving preoperative assessment of a congenital heart disease operation plan based on 3D printing. The method comprises the steps that normal person chest CT information is acquired, a normal person heart and lateral branch blood vessel stereo structure model is printed in a 3D mode, a normal person model is connected with an extracorporeal circulation machine to obtain normal person heart and lateral branch blood vessel physiological parameters, and then a standard contrast table is established; the normal person chest CT information is acquired, a doctor conducts simulated operation on a patient CT image, the normal person heart and lateral branch blood vessel stereo structure model after simulated operation is printed in a 3D mode, and the normal person model is connected with the extracorporeal circulation machine to obtain patient lateral branch blood vessel physiological parameters; the standard contrast table shows that the physiological parameter differ
