D215: FUNCTIONAL INTEGRATION IN ADDITIVE MANUFACTURING

A novel design for the integration of conventional rolling bearings into MEX-manufactured components 1Technische Universität Berlin, Germany; 2Technical University of Darmstadt, Germany Advances in additive manufacturing (AM) enable the use of AM components in demanding complex applications with high functional requirements. As a result, integrating standardized machine elements such as conventional rolling bearings is gaining growing relevance. However, limitations regarding achievable tolerances or surface qualities in the MEX process stand in contrast to strict specifications for bearing integration. This study introduces a novel interface element and a corresponding integration process that considers both bearing requirements and the layered structure of MEX components. Evaluation of electrical contacting approaches for additively manufactured conductive polymer composites Institute for Engineering Design, Technische Universität Braunschweig, Germany This paper presents a methodical investigation of ten types of contacts for electrically conductive polymer composites manufactured using additive manufacturing. The study examines the suitability of three different bonding agents for reducing contact resistance and measures the contact resistance of the contact systems as well as the tensile strength. Based on these results, design guidelines and a design catalogue are developed. The results show that although each contact type is fundamentally suitable, they should be adapted to the respective application using the derived design guidelines. Particle damping optimization and multi-material additive manufacturing of an atom chip bracket: a case study 1Institute of Product Development (IPeG), Leibniz University Hannover, Germany; 2Institute of Dynamics and Vibration Research, Leibniz University Hannover, Germany The powder bed fusion by laser beam of metals (PBF-LB/M) offers the possibility of directly integrating particle dampers during manufacturing. Building on an existing optimization tool, this article investigates the optimization and multi-material additive manufacturing (AM) of a bracket for an atom chip of a quantum inertial sensor. The bracket is optimized in terms of mass, stiffness, and damping properties, and subsequently manufactured using Scalmalloy and tungsten in a PBF-LB/M process. The results provide findings into component design as well as into the pre-processing phase of AM. A novel selection framework of joining technologies for metal additive manufacturing Technical University of Darmstadt, Germany Additive Manufacturing (AM) faces process limitations such as build-volume restriction and thermal distortion. While AM favors integral design, certain restrictions can be overcome by combining differential design with subsequent joining technologies (JT). Yet little is known about suitable JT selection in AM. To bridge this gap, established JT selection frameworks from conventional manufacturing (CM) were examined and adapted to AM. The resulting framework supports JT selection in AM based on joint design and AM-specific criteria while remaining applicable to CM and enabling combined designs. | ||
