Abstract: An anatomical movement simulation assembly and a method of simulating anatomical movements. One or more additive-manufactured body part models anatomically approximates a corresponding physical body part(s), or exhibits anatomical accuracy relative to the corresponding physical body part(s). The physical body part(s) modeled include a rib cage, lungs, diaphragm, tongue, jaw and teeth, vocal folds, and larynx, among other possibilities. Movement is imparted to the additive-manufactured body part model(s), for instance via pump, motor, or manual actuation, in order to replicate the physiologically normal movement of the corresponding physical body part(s). Educators, musicians, singers, actors, students, doctors, and patients, as well as others, may find productive use observing such anatomical movement simulations.
