A system and method of producing a medical support device is disclosed. The disclosure determining a three-dimensional shape of the medical support device for supporting an anatomical body part of a patient, the method executed by a computer and including acquiring body part geometry data describing a geometry of the anatomical body part; acquiring medical procedure data describing a medical procedure to be carried out on the patient; acquiring atlas data describing a general three-dimensional shape of the anatomical body part; determining, based on the body part geometry data and the medical procedure data and the atlas data, support device geometry data describing the geometry of the support device. The method and system further includes generative forming of the device by issuing at least one control command to the generative forming device for forming the medical support device based on the support device geometry data.
