“…This means that high school students can also benefit from it. The introduction of current research into the school is encouraged but is difficult . Therefore, the 3D-printing laboratory presented here offers an easy way to convey current research to future teachers in an exciting and relevant way, so that they can implement it in their lessons in high school later on.…”

Due to immense cost reduction and routine commercial availability, 3D printing has become the cutting-edge technology with enormous potentialalso for educational and applied chemistry. It opens the opportunity to print custom-made reactors, such as (micro) flow reactors. In addition, 3D-printing technology can simplify chemical reactions, such as heterogeneous catalysis, because reaction components, such as the catalyst, can be immobilized in the reactor by direct printing. Chemical experiments can thus be printed, and it becomes possible to transform an idea rapidly into a process, or a concept into an educational experiment as an elegant think and print approach. This paper introduces the concept of a 3D-printing lab in which students can learn the basics of 3D printing using a predesigned 3D-printed continuous flow reactor for photochemical reactions, especially for photooxygenations. Furthermore, the lab course includes other relevant topics of research, such as heterogeneous catalysis through the immobilization of the sensitizer in the reactor and the aspect of flow chemistry. The design of the reactor, the printing process, the immobilization, and the photochemical reaction were kept simple, especially because of application in teaching. The prototype presented here is a reactor printed from polypropylene with a porphyrin immobilized as a sensitizer by surface adsorption. Visible light is transmitted through a transparent polymer surface. As a model reaction, the photooxygenation of the terpene citronellol was used, which is also used in the fragrance industry.

In school and university education it is important to integrate current, innovative topics into curricula. Particularly in the field of education for sustainable development, there is a major need, based on the Sustainable Development Goals, to prepare the topics didactically, and to present them to school pupils at an early stage. This kind of research is known as "curricular innovation research". The production of biogas is an important topic as it is a source of renewable energy. More than 9000 biogas plants are currently in operation in Germany. It has been reported that no methane was measured in the state-of-the-art methods used in school experiments. A new experimental set-up was, therefore, developed to guarantee methane formation during these experiments, and to demonstrate the production of biogas in a hands-on way. Dried sugar beet was used as the substrate for biogas production. It was mixed with compost or garden soil which contains the microorganisms needed for biogas and methane production, and was used as the inoculum. A low-cost gas chromatograph served to measure the methane concentration in the biogas produced. In a first attempt to guarantee methane formation, sodium carbonate was added as a buffer to maintain the pH of the fermentation broth in the optimum range (7-8). Then, to avoid buffer addition, the optimum compost to sugar beet ratio was investigated in cooperation with the University of Hohenheim. Based on these results, methane formation was observed after 8 days, and methane concentrations up to 65 vol % were measured. Overall, this experiment constituted a hands-on way of demonstrating to school pupils the anaerobic digestion process through the production of biogas. This study also highlighted the major benefits of interdisciplinary cooperation in the field of curricular innovation research.
