FASER stands for “Fehlerfreies Additives Fertigen durch adaptive Sensorik zur Optimierung der Energie- und Ressourceneffizienz”. Conducted at the Technical University of Applied Sciences Wildau, it implements a comprehensive zero-defect strategy using market-standard equipment like the One Click Metal MPrint+ SLM machine and MPure powder removal station. These systems are enhanced with adaptive multi-sensor technology and intelligent process control to boost quality, cut energy use, and minimize material waste. Central to FASER is flexible camera-based multi-sensor integration, combining optical, thermographic, and spectroscopic methods for real-time monitoring in harsh SLM environments.

However, many commercial LPBF systems are based on closed hardware and software architectures, which limit transparency, process monitoring, and direct parameter manipulation during ongoing builds. While recent industrial machines increasingly provide standardized interfaces such as OPC UA for monitoring purposes, fine-grained, layer-wise process control remains restricted. The One Click Metal MPrint+ exemplifies this paradigm by relying on proprietary container-based job execution prepared using commercial software tools such as Autodesk Netfabb or Autodesk Fusion 360. This contribution presents an alternative approach that enables user-defined control of the MPrint+ system through a custom-developed G-code handling framework. Instead of executing complete print jobs as opaque containers, the proposed method establishes a direct network connection to the printer using its gRPC interface. Externally generated G-code is extracted, processed, and transmitted layer-wise to the machine, enabling direct interaction with the build process beyond standard job execution. The approach allows controlled variation of process parameters such as exposure strategies, hatch patterns, or recoating behavior during an ongoing build, thereby supporting efficient design-ofexperiment studies without requiring multiple independent print jobs. In addition, individual G-code commands can be executed interactively, enabling didactic use cases in which machine behavior can be directly observed and linked to abstract toolpath descriptions.

Nachwuchswissenschaftler*innenkonferenz N2 - The concept of this thesis is to optimize the manufacturing process of injection moulding tools by using additive manufacturing and thus contribute to environmental protection. For this purpose, the individual steps of the traditional manufacturing process are identified and analysed to determine which steps can be replaced by additive manufacturing. The first step is to clarify which mould components can benefit from additive manufacturing. In particular, the capabilities and limitations of additive manufacturing technologies must be considered. Furthermore, another focus is on how to optimize the cooling and temperature control of the tools. Potential savings through the use of lightweight or insulating surfaces will be examined. In addition to the technical feasibility, the cost-effectiveness of the concept will also be considered. Finally, the contribution of the concept to the reduction of the environmental impact will be evaluated. In particular, energy savings and the reduction of CO2 emissions are taken into account. The potential to optimize the injection mould manufacturing process and reduce environmental impact is significant. Using additive manufacturing can be an economic and environmental advantage.

To meet the legal requirements and save costs and time, a portable analysis method is to be developed. For this purpose, a concept study was conducted. It describes a portable measuring device for the quantitative detection of legionella using real-time PCR. The study includes the construction elements and conditions that are necessary for the collection, processing, and evaluation of the sample. It was found that commercially available PCR systems do not meet the size requirements and can only be represented by an in-house development. In addition, a microfluidic system must be developed that is designed for one-time use and low production cost.

Nachwuchswissenschaftler*innenkonferenz N2 - Additive manufacturing, also known as 3D printing, has gained tremendous importance in recent years. One of the areas where additive manufacturing is particularly useful is in the fabrication of electrodes. Electrodes are an important component of a wide range of applications, including electrochemistry, biomedical engineering, energy storage, analytics, electronics as well as life sciences. Traditionally, electrodes have been manufactured through costly processes such as etching, electroplating or cutting and milling. Additive manufacturing offers a new way to fabricate electrodes by depositing materials layer by layer (Yap et al., 2015). This opens up new possibilities for designing electrodes with complex geometries and structures that would not be possible using conventional methods. As a result, 3D printed electrodes are gaining interest in fields such as electromobility, water disinfection, manufacturing, and life sciences, which will be presented in this paper.

Nach Auftrag dieser wird Kautschuk mittels Gummispritzgießen auf die metallischen Grundkörper aufgebracht. In Klein- und Kleinstserien kann der Haftvermittler in präzisen Volumina händisch mit Hilfe eines Fluid-Dispensers aufgetragen werden. Allerdings verhindert dies eine Homogenität und Gleichheit der Schichtdicke, wodurch die Zuverlässigkeit und Stärke der Haftung variieren können. Als technische Lösung wurde ein Pipettierroboter avisiert. Mit Hilfe mehrerer mechanischer und elektrischer Adaptionen – so auch einer neuen Steuerungstechnik – wurden verschiedene Fluid-Dispenser auf 3-Achs-Portalfräsen integriert. Somit konnte die volle Funktionsfähigkeit erreicht werden. N2 - Chemical adhesion promoters are necessary for the production of long-term stable metal-rubber composites. After these have been applied, rubber is molded onto the metallic base bodies by rubber injection molding. In (very) small batches, the adhesion promoter can be applied in precise volumes by hand using a fluid dispenser. However, this prevents homogeneity and uniformity of the layer thickness, which can cause variation in the reliability and strength of adhesion. As a technical solution, a pipetting robot has been envisaged. With the aid of several mechanical and electrical adaptations - including a new control technology - various fluid dispensers were integrated on 3-axis portal milling machines. Thus, full functionality could be achieved.

For the automated application of adhesion promoters, a new control unit based on a mainboard for controlling 3D printers was used, with Marlin serving as the firmware. Adaptations were necessary in the area of motor currents, speeds, acceleration, sensitivity, print bed size and selection of mainboard and display. For the traverse paths, G-code was generated using a program in Python. For homogeneous and uniform wetting, the individual objects to be wetted are approached and the pipetting process is controlled. It was possible to establish the complete functionality.
