Das FabLab an der TechFak der Friedrich-Alexander-Universität Erlangen-Nürnberg
Forschungs- und Abschlussarbeiten
Gerade in der Forschung ist das FabLab hilfreich, um Ideen schnell praktisch umzusetzen und weiterzuentwickeln. Damit ist es eine gute Ergänzung zu klassischen Werkstätten mit Auftragsfertigung. Auf dieser Seite stellen wir wissenschaftliche Arbeiten vor, die im oder mit dem FAU FabLab entstanden sind.
Wenn auch du das FabLab für deine Forschung genutzt hast oder weitere solche Arbeiten kennst, freuen wir uns über einen Beitrag an kontakt@fablab.fau.de. Im Idealfall sind das 2–5 Sätze auf Englisch, die die Arbeit und den Zusammenhang zum FabLab zusammenfassen, ein Foto, ein Kontakt und eine zitierbare Quelle oder ein Link.
Um in deiner Publikation oder Arbeit auf das FAU FabLab zu verweisen, bitten wir darum, folgenden technischen Bericht zu zitieren:

Nicolas Johner and Lukas Maurer from the Helmholtz Institute Erlangen-Nürnberg for Renewable Energy (HI-ERN) are researching catalysts and surface coatings for hydrogen storage. They used the laser cutter in the FabLab to build a tray for 64 glass vials, which increased the number of samples that can be measured at once from eight to 64. This is useful for many applications in which the samples have to be shaken gently over a longer period, e.g. determining the point of zero charge or other titrations.

André Aichert investigates calibration techniques for flat-panel detector computed tomography systems. During his research he required a configurable phantom – a precise target with a known configuration – to relate reality to the detected image. Using the 3D printers at the FAU FabLab, a placeholder phantom matrix (pen) was created which allows metal bearing balls to be placed precisely. The metal balls can then be “seen” by the X-ray detector and used for calibration.
Navid Bonakdar from the Max Planck Institute for the Science of Light (MPL) built a chamber for the fabrication of giant lipid vesicles as model systems for cell membranes. This allowed researchers from MPL and FAU to evaluate membrane model systems for an overview study under physiological conditions.
Martin Schütz et al. introduced a novel, tailor-made UAV-based sensor platform, HeliSAR, that potentially allows interferometric SAR remote sensing based on a bistatic MIMO radar system. Many parts of the system were built in the FAU FabLab using the CNC mill, laser cutter, 3D printers, circuit board etching and many other capabilities.

In their publication, Schaller et al. investigated the local building blocks of packings of aspherical grains, as found in granular and glassy systems. To demonstrate their findings, they used the FabLab to produce 3D-printed physical representations of the local structures.
Heart valve implants represent the standard method to treat severe malfunctions of human aortic valves. To further optimize biological implants, their tissue component, made of e.g. porcine pericardium, needs to be characterized in detail. As part of a master’s thesis, Nina Lehenberger developed a test station for biaxial tensile testing of biological tissue. The FAU FabLab provided a laser cutter so that tensile samples could be cut out of the tissue and the measurements of porcine pericardium could be carried out.

Robert Weigel modelled ellipsoid packing for his bachelor’s thesis. Such models are vital for understanding unstructured packing processes of materials such as sand or glass. To visualize and demonstrate the theoretical work, 3D-printed ellipsoid structures were produced in the FAU FabLab.

Toni Bartsch used the FabLab during his bachelor’s thesis, designing a programmable, constant, spike-free power supply for integrated circuit testing. For safety and practical use in a research and testing environment, a protective case made of solid aluminum and an acrylic front cover had to be designed and manufactured.

In a bachelor’s thesis, Timo Voigt investigated the use of a laser cutter for bending acrylic, thus extending it from a 2D cutting tool to a 3D sheet prototyping machine.

Sonstiger Einsatz
The Eu:CROPIS satellite was developed by the German Aerospace Center (DLR) to simulate the effects of lunar and Martian gravity on the germination and growth of tomato plants for future interplanetary missions. Sebastian Strauch, a researcher in the Cell Biology group, used a laser cutter at the FAU FabLab to manufacture Mylar foil stencils needed in the production of a circuit board used on board the satellite.
In the investigation of quasicrystals by Sebastian Kapfer, a two-dimensional model was cut out of acrylic at the FAU FabLab. Quasicrystals have additional degrees of freedom (phasons) beyond those known from periodic crystals (phonons). The project investigated how these lead to new kinds of topological defects.
