Structural Timber by Individual Layer Fabrication (ILF) [22.01.2021] Bunzel, Frauke; Project leader; frauke.bunzel@wki.fraunhofer.de Asshoff, Carsten; Doctoral researcher; carsten.asshoff@wki.fraunhofer.de Fraunhofer Institute for Wood Research Wilhelm-Klauditz-Institut WKI In order to produce future-oriented timber structures in the building industry that meet the requirements of ecological and economic sustainability, an additive manufacturing process with wood chips is being developed using the new approach of individual layer fabrication (ILF). In first steps, established wood chip fractions and adhesive systems from the wood-based materials industry are used e. g. for particleboards or oriented strand boards. For an acceptable adhesive-wood-chips ratio the amount of adhesive must be as low as possible, which is one of the challenges in developing ILF, see Fig. 1. In addition to …

Integration of Additive Manufacturing in the Construction Process [08.01.2021] Mawas, Karam; Doctoral researcher, k.mawas@tu-braunschweig.de, TU Braunschweig, Institute of Geodesy and Photogrammetry (IGP) Gerke, Markus; Project leader, m.gerke@tu-braunschweig.de, TU Braunschweig, Institute of Geodesy and Photogrammetry (IGP) Maboudi, Mehdi; Associated scientist, m.maboudi@tu-braunschweig.de, TU Braunschweig, Institute of Geodesy and Photogrammetry (IGP) Riedel, Björn; Associated scientist, b.riedel@tu-braunschweig.de, TU Braunschweig, Institute of Geodesy and Photogrammetry (IGP) Additive Manufacturing (AM) allows us to print objects in unprecedented and novel ways, pushing the boundaries of what was previously possible in construction. By seamlessly embedding the process of the design directly into the printing process, ever more complex and free form objects can now be realized. Nonetheless, AM remains a challenging and involved process that is influenced by a variety …

Wire and Arc Additive Manufacturing (WAAM) of Complex Individualized Steel Components [01.01.2021] Müller, Christoph; doctoral researcher, christoph.mueller@tu–braunschweig.de, TU Braunschweig , Institute for Structural Design (ITE) This sub–project of the SFB 277 deals with the design process of components for additive manufacturing by Wire and Arc Additive Manufacturing (WAAM). In contrast to large industrial sectors such as mechanical engineering, aeronautical engineering or medical technology, components in the construction industry have to be designed under different general conditions. If no building system is used to create a structure, the components are usually individual. These components are usually used in the building as a single part or in small quantities. With the implementation of additive manufacturing processes, these components are usually free–form …
