Marios Mouratidis, M.Sc.
Vita
Marios Mouratidis studied Literary, Cultural and Media Studies with Language and Communication as a minor (B.A.) and Human Computer-Interaction (M.Sc.) at the University of Siegen. Since early 2020, he has been a research associate at the Chair of CSCW and Social Media in the EU and NRW-funded Center for Smart Production Design.
His research interests include participation, maker methodologies, digital fabrication, innovation, and come_IN computer clubs, among others, in Palestine. He pursues qualitative research approaches.
During his studies, he contributed to various research projects at the Chairs of Information Systems and New Media and CSCW and Social Media as a student assistant.
From 2016, he focused his work on field research in Palestine and coordinated the DAAD-funded project YALLAH! You All Are Hackers, where he supervised students in small research projects around social innovation and taught qualitative research methods for empirically based design. Since then, he has coordinated the research projects of the Chair of Information Systems and New Media in Palestine and also worked in the BMBF-funded project PiHub and the EU-funded project Fostering Entrepreneurship in Science, Technology, Engineering & Math (FESTEM).
With his master’s thesis “(Un-)Sustainable ICT-interventions in occupied Palestine,” he wrote a case study summarizing nine years of research data on come_IN computer clubs in Palestine and examining factors for sustainable ICT-centered communities.
Before and during his studies, he worked as a freelancer in media design (web, print, mobile) and game design.

Frohn-Sörensen, P., Mouratidis, M. & Engel, B. (2023)Design of non-assembly joints incorporating randomness generated through a publicly accessible 3D print farm
IN Procedia CIRP, Vol. 120, Pages: 129–134 doi:10.1016/j.procir.2023.08.024
[BibTeX] [Abstract] [Download PDF]Traditionally, technical hinge joints are made of multiple parts, which need to be assembled. Additive manufacturing (AM) provides the option to overcome these assembly steps since movable mechanisms become manufacturable in a streamlined manufacturing route. The feasibility for such so-called “print-in-place” approaches has been proven and punctual design recommendations are available in additive manufacturing community knowledge. Still, a generalized assessment of the influencing parameters is absent because the layout of the gap of a joint highly depends on the AM boundary conditions. This study considers manufacturing simple hinge joints by the method of fused filament fabrication (FFF) on commercially available 3D printers. In order to generate representative scatter, the manufacturing jobs of the specimens are placed on a 3D print farm in a university fab lab. The machines are utilized and maintained by a public community, which also utilizes different materials suppliers in a randomized manner. Series of print-in-place joints are printed with statistically relevant repetitions under variation of the hinge joint gap, print orientation and AM layer height. After manufacture, the joints are tested to provide statistical information on force necessary for motion. The results indicate that with a reduction of gap width, the forces necessary to initially release and move the joints begins to rise until complete fusion of bushing and hinge axis. If the hinge axis is aligned with the Z-axis of the 3D printing process tighter critical clearances become manufacturable than with a hinge alignment in the XY-plane of the 3D printer. Moreover, reduced scatter of the results is obtained in the Z-axis. As for the layer height, it is seen that layer heights of 0.1 mm might lead to increased release forces while the largest adjusted layer height of 0.3 mm led to increased forces during the hinges’ motion.

Schreiber, F., Frohn-Sörensen, P., Mouratidis, M., Engel, B. & Manns, M. (2023)Case Study on the Additive Manufacturability of Printed Soft-Robotic Bending Actuators
IN Procedia CIRP, Vol. 120, Pages: 720–725 doi:10.1016/j.procir.2023.09.065
[BibTeX] [Abstract] [Download PDF]In order to flexibly handle products with varying shapes and materials, soft robotic pneumatic network actuators (pneunets) have been proposed due to their compliant behavior. Pneunets are manufactured with manual casting or with additive manufacturing (AM). In this work, the four AM technologies fused filament fabrication (FFF), stereolithography (SLA), selective laser sintering (SLS) and polyjetting (PJ) are compared for manufacturing pneunets. Results are analyzed regarding manufacturability, deflection behavior and airtightness. SLS and FFF show best results and least manufacturing restrictions for thermoplastic polyurethane pneunets. SLA and PJ lead to manufacturing specific deficits and critical material failures during pneunet operation.

Rüller, S., Aal, K., Mouratidis, M. & Wulf, V. (2020)Messy Fieldwork: A Natural Necessity or a Result of Western Origins and Perspectives?
Companion Publication of the 2020 ACM Designing Interactive Systems Conference. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 185–190 doi:10.1145/3393914.3395864
[BibTeX] [Abstract] [Download PDF]With this Provocation, we aim at starting a dialogue between researchers who struggle with applying qualitative and ethnographic methods and following approaches in non-Western settings. Going by the book might not be an option when conducting research in politically charged or un-stable regions. Local politics, social pressure and even people’s personal safety are aspects that require consideration. Based on our experience from conducting fieldwork in Morocco, Palestine and Botswana, we reflect upon the difficulties we came across. We argue that, messiness, to some extent comes naturally with immersive fieldwork. On the other hand, in order to find ‘clean’ ways of conducting ethnographic fieldwork in non-Western contexts, novel forms of (applying) methods are needed. By providing questions regarding three different aspects (applying methods on the Ground, Ethics, and Participation) we encourage researchers to reflect upon their own experiences.

[BibTeX] [Abstract] [Download PDF]There are several frameworks and approaches, addressing how to conduct ethnographic and qualitative field work in various settings. However, going by the book might not be an option when conducting research in politically charged, unstable or simply non-western regions. Politics, social pressure and even someone’s personal safety might be necessary to consider. Another important area to consider are research ethics. Privacy policies might do their work with regard to existing laws which differ from each country and should ensure no harm for all involved parties, but how can this be guaranteed and does it also cover all aspects of ethics? Including stakeholders as a basis for user-centered work and design is common. But what does participation mean in such contexts? The questions are: What is important to consider when conducting ethnographic field work in such settings? How can we foster different degrees of genuine participation? How can we ensure, that the work we do is ethically correct without endangering the research outcome? In this workshop, we invite researchers and practitioners to rethink existing methods and approaches and start working on guidelines, that better serves the needs of such specific and to some extent critical circumstances.
