Materials Mechanics, Design Theory, and Digital Fabrication Research

Bauhaus University Weimar is globally renowned for its distinctive approach to design education, seamlessly blending aesthetics with functionality. However, the university’s influence extends far beyond design, with disciplines such as architecture, civil engineering, and materials science playing equally pivotal roles. Junior Professor Dr.-Ing. Luise Göbel, who leads the chair in Materials Mechanics, exemplifies this multidisciplinary spirit. Her research is primarily focused on sustainable and digital building practices, an area where 3D printing offers revolutionary potential. Having worked with additive manufacturing for nearly a decade, Dr. Göbel considers it a cornerstone of her scientific inquiry. She highlights its significant capacity for innovation within the construction industry and its profound scientific relevance in materials mechanics. Dr. Göbel describes the technology’s impact as having “enormous resonance in the scientific community,” underscoring its central role in her own research endeavors. She particularly values 3D printing’s ability to facilitate rapid demonstrations, produce custom components with intricate geometries, and accelerate the prototyping process. For instance, she explains, “With 3D printing, we can test geometries that we later want to implement using large-scale concrete printers. In that sense, its influence on work processes is truly substantial and transformative.” This allows for iterative design and testing cycles that were previously unimaginable, pushing the boundaries of what is possible in modern construction.

Complementing Dr. Göbel’s engineering perspective, Dr. Michael Braun represents a more artistic and theoretical discipline. As a product designer and distinguished design scholar, he has been an integral part of the Faculty of Art and Design in the Chair of Design Theory and Design Research since 2018. His view on the potential of 3D printing, while distinct, is deeply complementary, fostering a holistic understanding of the technology. Dr. Braun’s research delves into contemporary design cultures, exploring digital design processes and their impact on creative practice. In this realm, 3D printing plays a critical and multifaceted role. The technology has been a constant companion throughout his academic journey, dating back to the very beginning of his studies. From his unique vantage point, additive manufacturing possesses the profound ability to “raise new questions about the relationship between design, material, and technology,” thereby positioning it as a significant cultural, creative, and epistemological field of tension. This intellectual curiosity was evident in his master’s thesis, which focused on 3D printing as a means to explore how digital tools could dissolve the traditional separation between design conceptualization and physical execution. He further advanced this line of inquiry in his doctoral research, where he meticulously examined potential advancements in additive manufacturing and the innovative applications of robotic 3D printing, pushing the boundaries of digital fabrication and artistic expression.

Innovative Projects: StimuCrete and Digital Craftsmanship

Beyond its utility for rapid prototyping and idea visualization, Professor Göbel is deeply involved with 3D printing through her groundbreaking project, StimuCrete. This ambitious initiative, generously funded by the Federal Ministry of Research, Technology, and Space, is dedicated to investigating the rheological behavior of concrete. The overarching goal of StimuCrete is to imbue concrete with intelligent properties, making it responsive and adaptable. While this concept may initially sound complex, it promises to usher in a new era of decisive progress in 3D concrete printing. In essence, the project aims to develop a concrete mixture that remains flexible and flowable during the precise printing process, yet solidifies almost instantaneously upon exiting the print head. This immediate hardening is crucial for structurally supporting subsequent layers of material, allowing for complex geometries and faster construction. Dr. Göbel succinctly articulates the project’s ambition: “We want to make it possible to switch this behavior on at the push of a button,” highlighting the control and precision they seek to achieve with StimuCrete, thereby revolutionizing the capabilities of large-scale additive construction.

Dr. Braun, from his design-centric perspective, views 3D printing as a powerful tool capable of fundamentally transforming traditional creative processes. Historically, manufacturing processes have been characterized by a strict separation of design and execution. Consider, for example, the conventional roles of an architect who designs a building and the construction company that later builds it. With the advent of additive manufacturing, Dr. Braun argues that these once distinct phases are no longer isolated. He posits: “Design is no longer something that is completed before fabrication, but something that continues to evolve during fabrication.” This continuous interplay, he explains, generates fascinating creative tensions and opens new avenues for artistic expression. The inherent mechanical precision offered by 3D printing raises compelling questions about how design processes adapt and change under digital conditions, and what becomes of traditional craftsmanship in this evolving landscape. These profound research questions were the initial impetus that drew Dr. Braun to 3D printing. What particularly captivates him is the concept of “digital craftsmanship,” a paradigm where the focus shifts away from an idealized notion of perfection. Instead, it critically embraces and engages with deviations, explores the intricate behavior of materials during the printing process, and celebrates emergent qualities. In short, Dr. Braun advocates for viewing the inherent imperfections and unexpected variations that occur during the printing process not as “errors” to be corrected, but rather as a rich and dynamic creative resource that can lead to unique and innovative outcomes.
