Additive Manufacturing in Construction
AMC TRR 277

Associates Overview

Guest Researchers

The AMC invites outstanding researchers from various disciplines, especially from abroad, as guests for longer and shorter stays. They are usually in close exchange with individual subprojects and support the project staff with their expertise. In lecture formats, they present their own research and discuss it together with the staff. At the end of each stay, the results obtained are published in joint publications. Proposals and invitations for guest researchers can be submitted to the AMC at any time.

Associated industry partners

Associated industry partners support the AMC in order to accelerate the transfer into application. In this way, the bridge between pure basic research and industry is to be further expanded. Along associated industry partners the technological value chain is bundled and a high relevance in practice is generated. Proposals for the association of industrial partners can be formulated by any AMC scientist to the AMC Executive Director. The speakers finally decide on an association.

Associated Scientists

Associated scientists and research groups whose scientific profile is closely related to the AMC and its projects. Associates are invited to participate in all AMC events and are supported by the AMC in the realization of their own projects. Proposals and invitations can be formulated by any AMC scientist to the AMC Executive Director. The spokespersons finally decide on an association.

Alumni

The circle of alumni includes all former employees, former guest scientists and former associated members of the AMC. Even after the official departure, the alumni continue to work together on the mutual use of the experience potential and on the development of a network. Likewise, the AMC should receive new impulses from its alumni.

Guest researchers

AMC-Mercator-Fellow Asst. Prof. Dr. Mariana Popescu is from the TU Delft and within architectural design, her area of expertise is computational and parametric design with a focus on digital fabrication and sustainable design. Her extensive involvement research projects related to promoting sustainability has led to a multilateral development of skills, which combine the fields of architecture, engineering, computational design, and digital fabrication. More specifically, her research is centred around digitally fabricated stay-in-place formwork systems for complex concrete geometries using 3D-knitting techniques. Her interest in additive manufacturing technologies, structural efficiency, and fabrication with material effectiveness is closely related the research of TRR 277 Additive Manufacturing in Construction (AMC). In 2022, Mariana Popescu was appointed as AMC-Mercator-Fellow by the TRR 277 AMC in honor of her contribution to the AMC One of her contributions within the AMC was the joint development of a cross-university student summer school/ seminar between TU Munich, TU Braunschweig, and TU Delft in 2022 and 2023. The seminar aims to bridge fundamental principles of geometric computation and design and use these insights to develop new algorithms and tools for 3D shape generation, simulation, structural design, and manufacturing in design and engineering. Students joining from all three institutions are taught innovative computational design solutions for advanced manufacturing and construction at various scales through the development of a textile reinforced bridge demonstrator. The prototype combines digital from finding techniques, 3D knitted flexible formworks, and shotcrete 3D printing, thus bringing together researchers from several projects within the AMC (C06, A04, B04, C02, C03, C04). The cooperation with the AMC has made it possible to scale-up and automate a previously developed technique. This is an important contribution as it takes one step closer to being able to apply these methods in a real-world environment in terms of construction. Moreover, in bringing together researchers and teaching students from different universities and different faculties the completion of the prototype also proves the importance of cross-disciplinary collaboration and, importantly, the education of a new type of professional in the field of construction. Beyond this collaboration phase, new synergies have been created with researchers from the AMC and a sustained collaboration beyond the term of the fellowship is expected to emerge. In the short term this can be started through joint guidance of master thesis students. Finally, Within the remaining time of the collaboration in 2023, the aim is to distil the opportunities and challenges identified within the development of the prototype and develop a joint research grant proposal that would enable a sustained collaboration.

Guest researchers

AMC-Mercator-Fellow Prof. Dr. Nicolas Roussel is in charge of the research activities dealing with rheology and processing of construction materials at the Navier Laboratory, FRANCE. He is the founding editor of the RILEM technical letters journal, president of the RILEM association and has received in 2007 the Robert L’Hermite award for his work on rheology of fresh concrete. With a Thompson Reuters H-index of 54 and more than 8.000 citations, he is the author or co-author of more than 130 papers in scientific journals such as Cement and Concrete Research, Physical Review letters or Journal of Non-Newtonian Fluid Mechanics. His research focus spreads from concrete rheology and rheometry to the understanding of construction processing technologies. Thereby his work covers various technology readiness levels and includes mixing and dispersion, centrifugation and granulation, vibration and compaction, molding, spraying and coating along with automation in construction. In 2022, Nicolas Roussel was appointed as AMC-Mercator-Fellow by the TRR 277 AMC in honor of his contribution to the AMC. Within the context of its AMC cooperation, he recently contributed to a workshop on “Materials and Processes in Additive Manufacturing” at TUBS, having the opportunity to see and discuss the research results and outputs of several AMC PhD and post doc researchers. This intensive exchange has led to the planning of a number of joint and collective publications dealing with the rheology and thixotropy of cement-based materials. According to Nicolas Roussel, the cooperation with the AMC as AMC-Mercator-Fellow “offers the opportunity to directly interact with high-level PhD students also in the coming years and thus to foster the AMC’s strategic topics for the European industry”. As a result of the above interactions, Prof. Dirk Lowke and Prof. Nicolas Roussel are planning for the submission of Franco-German ANR/DFG research project.
