7th Summer School in Medical Physics 2026

We are happy to announce our 7th Summer School in Medical Physics about 3D Printing Techniques and Concepts in Medical Physics, to be held in August and September 2026. The course is organized under the auspices of the Heidelberg Institute of Radiation Oncology (HIRO) in close cooperation with our partners (see below). The summer school is subdivided into an online phase of about five weeks and an attendance phase of one week. The attendance phase is organized as hybrid model, such that all sessions of the attendance phase are additionally available online via Zoom. Thus, participants can decide to follow the course online and on site or 100% virtually. The teaching language is English. 

This summer school provides a comprehensive introduction to the role of 3D printing in medical physics, with a particular focus on applications in radiotherapy. Participants will gain insight into how additive manufacturing technologies are currently used in clinical and research settings, as well as the opportunities and challenges associated with their implementation. The program begins with a refresher on key radiotherapy principles to ensure a common foundation for all attendees. Building on this, we will explore different radiotherapy concepts where 3D printing can offer innovative solutions, supported by examples of ongoing projects and applications. Participants will also be introduced to the software workflows required for medical 3D printing, from image segmentation to model preparation and printer operation. In addition, we will address important regulatory and quality assurance considerations that arise when producing 3D-printed devices intended for patient use. 

A central highlight of the summer school is a hands-on workshop covering the complete development cycle of a 3D-printed phantom. The course concludes with an overview of current applications and future directions of 3D printing in medical physics, providing participants with practical ideas they can apply in their own institutions. Participants can also join an optional project management as well as presentation and rhetoric workshop to improve their skills.  

Furthermore, we invite everyone to submit their abstracts to contribute to our science slam or our poster session. We are very much looking forward to your registrations and your contributions. 

We are very happy to announce prizes for the science slam and the poster session. Therefore, we invite all applicants to submit abstracts for the science slam or the poster session (in addition to the regular application documents) to win one of the following prizes: 

• First Prize for Best Presentation of the Science Slam: €300
• First Poster Prize: €250, sponsored by Leo Cancer Care
• Second Poster Prize: €150, sponsored by Leo Cancer Care

The abstract should be in the field of medical physics in radiotherapy or imaging. Thus, it does not need to have a focus on 3D printing techniques and concepts. We are looking forward to receiving your abstracts to learn more about your research projects. Day and time of the science slam and poster session see program. 

Please download and read the Abstract Guideline below. However, you can also register without abstracts.

Our summer school 2026 starts with an online phase of about five weeks. During this period, participants get access to the virtual learning platform Moodle which provides all learning materials such as pre-recorded video lectures and lecture notes as PDFs as well as short tasks. Furthermore, live online sessions on Zoom are scheduled (see program). 

The online phase is concluded with the first mandatory online test consisting of multiple-choice questions about all topics taught during the online phase. The test can be done during the last two weeks of the online phase whenever participants have time, and its successful completion (50% of points indicated) is a prerequisite to participate in the hybrid attendance phase.

Please also download and read our technical requirements to attend our hybrid summer school: 

The attendance phase in Heidelberg is hosted as a hybrid event and thus, all sessions are available as a so-called live online phase to those who attend online only.

Lectures by our national and international experts are usually scheduled during the morning sessions. More interactive sessions such as a workshop, the science slam and the poster session as well as interactive discussion rounds take place during the afternoon to strengthen active participation and to initiate scientific exchange between experts and participants. We also include networking activities for online participants into the schedule of the hybrid attendance phase. E.g. online participants can have virtual lunch breaks with the host and the course leaders. 

The whole summer school is concluded by the second mandatory online test (multiple-choice questions; 50% of points indicated need to be reached) about all topics taught during the hybrid attendance phase (duration of second online test see "Dates and Program").

The attendance phase in Heidelberg is hosted as a hybrid event and thus, all sessions are available on Zoom to those who attend online only.
