New learning and teaching media can complement our work as lecturers and trainers and enrich the transfer of knowledge for students. The present offers a wide range of possibilities for this and it is interesting and important for everyone involved to evaluate the potential of the corresponding method and to examine its added value.

The following studies will be used to apply the possibilities of 3D printing, AR (the pure viewing of additional image information) and MR (possibility of additional interaction) and to impart specialist knowledge.The comparison with conventional teaching is an indispensable and valuable tool here.

The subject of independent software development is the integration of data glasses or other media into preoperative planning or intraoperative application. Conventional neuronavigation is the benchmark against which augmented or mixed reality must be measured.

Procedures are to be developed and tested for their suitability in practice that allow the surgical site to be registered and the contours of structures of interest to be reproduced. The end point and orientation should be guided, i.e. navigated neurosurgery with the familiar precision and reliability offered by current procedures in their routine application.

Due to its properties and availability, 3D printing allows for a wide range of applications and is of growing interest, e.g. to investigate the influence of a patient-specific 3D model on the understanding of disease and insight into therapy.

In particular, this type of presentation of findings should have an impact on doctor-patient communication and understanding in the context of the informed consent discussion for planned operations or interventions.
