Circular use of polylactide PLA in additive manufacturing: Real-waste recycling process chain and mechanical property window
In: Resources, Conservation & Recycling Advances, Volume: 30, S. 200330, DOI: 10.1016/j.rcradv.2026.200330
Schlagwörter: Additive manufacturing; Circular economy; Fused filament fabrication; Polylactide; Recycling; Sustainable Development Goals
Abstract Links

The proliferation of plastics across diverse product sectors has underscored the urgent need for sustainable waste management, as conventional plastics persist in the environment for decades. Additive manufacturing (AM) technologies, now widely adopted in both industry and private use, contribute significantly to decentralized plastic waste streams, primarily through prototyping and residual material accumulation. Despite recent efforts, most studies on recycling AM-derived polylactide (PLA) waste focus on clean, laboratory-origin scrap, single reprocessing cycles, or do not explicitly present a realizable recycling machinery concept. This study presents an end-to-end mechanical recycling process, using practical machinery to convert diverse, multi-sourced PLA waste from industrial and community AM activities into new filament. Mechanical properties are systematically evaluated through designed experiments, examining the influence of the number of reprocessing cycles and mixing ratios of recycled and virgin PLA. Results demonstrate moderate but manageable reductions in strength and stiffness with an increasing number of reprocessing cycles, supporting the technical feasibility of utilizing recycled PLA in fused deposition modeling processes. The methodology puts forward a realistic pathway for decentralized recycling, helping to close material loops and promote circular economy principles in the context of AM. Broadly, these insights contribute to more sustainable manufacturing strategies by reducing reliance on primary resources and supporting the objectives of the Sustainable Development Goals.

Recreational making–related beliefs in adolescents: developing a comprehensive belief category system
In: Education and Information Technologies, DOI: 10.1007/s10639-026-13969-3
Schlagwörter: Gender; Elicitation study; Low SES; Making activities; Theory of planned behavior
Abstract Links

Making activities, such as creating individual artifacts via 3D printing, offer great potential for adolescents to acquire skills beneficial for their digital empowerment. To develop interventions that may increase adolescents’ making engagement, their making-related beliefs need to be explored and systematized. Therefore, based on the theory of planned behavior (TPB; Ajzen, 1991), this interview study elicited beliefs regarding recreational making with N = 29 adolescents. The sample included both female adolescents and those from a low socioeconomic status to ensure that beliefs specific to these groups were not overlooked. The key research output is a category system that aligns with the TPB and differentiates salient beliefs that are important for recreational making. The discussion focuses on how this category system may be applied in future studies to create qualitative interview guidelines and quantitative questionnaires regarding making-related beliefs. The study also discusses how this category system can inform the development of tailored interventions and educational programs that resonate with adolescents’ beliefs.

Designing for Resilience: Fostering Ponds of Stability with Computer Clubs in Palestine
In: Proceedings of the 2025 CHI Conference on Human Factors in Computing Systems, S. 1–18, DOI: 10.1145/3706598.3713253
Abstract Links

Addressing the complexities of conflict-affected regions remains a critical challenge for Human-Computer Interaction (HCI). This paper examines the establishment of computer clubs in Palestinian refugee camps, where efforts to create sustainable interventions weighed against the instability of prolonged conflict. To capture this dynamic, we introduce the notion of ‘adaptive ponds of stability,’ which extends the ‘tech public of erosion’ framework [12]. While the latter emphasizes systemic depletion of socio-technical infrastructures, adaptive ponds of stability highlight efforts to foster temporary spaces of resilience. The clubs became hubs of learning, respite, and collaboration—offering moments of routine and empowerment amidst disruption. Reflecting on this, we advocate for a paradigm shift from sustainability to resilience as the primary design goal in unstable contexts. Our findings emphasize adaptability, local agency, and cultural sensitivity that respond dynamically to context-specific challenges, offering a nuanced approach to advancing HCI interventions in conflict-affected settings.

Menstrual Mindsnacks - Exploring Social Implications of a Speaking Tampon Dispenser
In: Proceedings of the 12th International Conference on Communities & Technologies (C&T 2025), DOI: 10.48340/ct2025-1018
Abstract Links

This study explores the stigma associated with menstruation and examines methods to enhance menstrual hygiene and health awareness, as well as normalization through a socio-technical system. Around half of the world population is in need of menstrual hygiene products. Although soap and paper towel dispensers are now considered standard equipment in public bathrooms all over the world, this is not the case for period products like tampons and pads. Moreover, stigmatization of menstruation largely exists during adolescence and is caused by feelings of shame, disgust, and the fear of not being taken seriously. This can often be traced back to experiences of reactions by authoritative figures and male acquaintances in the participants’ lives and often subsides with adulthood. These emotions are reinforced by a lack of open discussion on the topic, ultimately leading to a societal taboo. Following a design case study approach, a speaking tampon and pad dispenser was co-designed with affected persons and evaluated in a public restroom. The prototype provides users with educational content through audio playback whenever it is touched, delivering useful information about the duration, effects, and management of menstruation. Because the prototype is deployed in a public restroom, the interaction also opens space for social exchange. Preliminary user feedback on the prototype suggests that it has the potential to foster discussion and improve menstrual health awareness. By promoting communication and providing accessible information, this dispenser can significantly influence societal attitudes towards menstruation, especially with more vulnerable groups.

Design of non-assembly joints incorporating randomness generated through a publicly accessible 3D print farm
In: Procedia CIRP, Volume: 120, S. 129-134, DOI: 10.1016/j.procir.2023.08.024
Schlagwörter: fablab; additive manufacturing; FFF; hinge joint; non-assembly; PLA
Abstract Links

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.

Coping with Messiness in Ethnography: Authority, Bias and Immersion in ethnographic Fieldwork in the non-Western World
In: Extended Abstracts of the 2021 CHI Conference on Human Factors in Computing Systems, S. 1–5, DOI: 10.1145/3411763.3441328
Abstract Links

Ethnography has firmly established its position in the Human-Computer Interaction (HCI) community. Many studies have benefited from following ethnographic approaches to arrive at a grounded and comprehensive understanding of the respective research context. Applying that to the non-Western world, however, comes with challenges for researchers. Aside from ethical concerns which have been addressed in the past, we want to use this workshop to foster conversations and discussions on authority, bias and immersion when conducting ethnographic field work in the non-Western world – especially as a Western researcher. The main objective of this workshop is to exchange experiences and to identify common aspects and ways of overcoming, coping with or even embracing the messiness in ethnographic work and derive guidelines based on these discussions.

Messy Fieldwork: A Natural Necessity or a Result of Western Origins and Perspectives?

Abstract Links

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.

(Coping with) Messiness in Ethnography – Methods, Ethics and Participation in ethnographic Field Work in the non-Western World
In: CHI EA '21: Extended Abstracts of the 2021 CHI Conference on Human Factors in Computing Systems, S. 1-5, DOI: 10.1145/3411763.3441328
Abstract Links

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.
