Ehsan Baharlou will present his research titled “Material Tectonics” on Saturday, October 21 at the 2023 ACSA/AIA Intersections Research Conference: Material Economies. Dr. Baharlou’s research focuses on integrating material capacities and fabrication limitations into design processes. He will delve into material tectonics, focusing on approaches to develop eco-resilient structures using robotic additive manufacturing. The project highlights the difficulties and potentials of 3D printing eco-resilient materials in order to reduce the embodied energy of the building industry. He will present during the session on material technologies.

Additive Tectonics
“When a structural concept has found its implementation through construction, the visual result will affect us through certain expressive qualities which clearly have something to do with the play of forces and corresponding arrangement of parts in the building, yet cannot be described in terms of construction and structure alone. For these qualities, which are expressive of a relation of form to force, the term tectonic should be reserved.”
— Eduard F. Sekler (1960), “Structure, Construction, Tectonics”, in Structure in Art and in Science.
Description
Advances in computational design methods and fabrication techniques provide new possibilities for architectural designers to consider different paradigms for design and making. These paradigms emphasize the relationship between formation and materialization. Through robotic additive manufacturing, designers can construct buildings or building elements quickly.
The studio “Additive Tectonics” explored the tectonic expression of additive manufacturing in different architectural contexts, from constructing affordable housing with earth materials to investigating the construction of settlements on other planets. The studio focused on the exploration of such architectural tectonics as an abstracted skin or wall system; a tower or a column as a structural element; a vault or a shell as a roof system; a hut or a shed; or other, new building tectonics. One-to-one structures were designed for the North Terrace at the University of Virginia’s Campbell Hall.
Students explored additive tectonics through three stages. The material system development stage demonstrated various materials—such as bio-based, bio-degradable, or bioplastic materials—and their properties and limitations in additive manufacturing. In computational design development, students considered the material properties and fabrication constraints in prototyping. Finally, robotic additive construction—which can be defined as abstraction, formation, rationalization, and materialization to explore novel tectonics—enabled students to execute their design prototype to examine their design’s tectonic potential in building an architectural element.
A series of integrative workshops supported this studio. Formation workshops introduced Grasshopper as a CAD software that can be used for form generation. Materialization workshops presented students with a numerical-based fabrication process. Students learned to control an industrial robotic arm and 3D-print tectonic prototypes.

Introduction to Robotic Additive Manufacturing
“The manifest form—that which appears—is the result of a computational interaction between internal rules and external (morphogenetic) pressures that, themselves, originate in other adjacent forms (ecology).”

Description
Emerging advanced technologies utilize the developments of rapid additive manufacturing (RAM) to scale up the design from small scales to building scales. Robotic additive manufacturing techniques allow designers to construct buildings or materialize building elements in a short time. Robotic additive manufacturing, which usually necessitates a layer-by-layer approach or lattice structure, requires understanding the relationship between form, material characteristics, and robotic fabrication techniques.
The elective course “Introduction to Robotic Additive Manufacturing” introduced students to robotic additive manufacturing for architectural design. Students established their fabrication system to explore the practical potential of this technique in an ecological construction. They applied robotic 3D-printing with pellet-based extruders (Biodegradable materials) or paste-based extruders (quasi-solid materials).
Students were introduced to a variety of robotic additive manufacturing techniques, including Fused Deposition Modelling (FDM). They learned the principles of a design-to-fabrication process that incorporates design strategies, fabrication constraints, and material properties. This process involves 1) 3D-modelling a deep screen, wall, or façade system; 2) preparing materials and design for fabrication; and 3) robotic 3D-printing a design deep surface. Students then applied these principles on designing and prototyping a scale model of an ecological building skin/deep surface.
Two workshops supported this course. The first was on computational design, a parameter-based design process that includes sketching, designing, simulating, and manufacturing a conceptual design. The second focused on robotic 3D-printing, which is a numerical-based fabrication process that includes advanced robotic controls and programming.

Introduction to Cognitive Design and Fabrication
“The manifest form—that which appears—is the result of a computational interaction between internal rules and external (morphogenetic) pressures that, themselves, originate in other adjacent forms (ecology). The (pre-concrete) internal rules comprise, in their activity, an embedded form, what is today clearly understood and described by the term algorithm.”

Description
Advances in design computation methods and fabrication techniques provide new possibilities for designers to consider different paradigms for design and making. These paradigms emphasize the relationship between formation and materialization. Form manifestation can be investigated through behavioral, emotional, and cognitive approaches. Cognitive and emotional design approaches center humanity in production processes to address their needs. The implication of human-centered design methods will change the production of goods from mass-production and mass-customization to more personalized manufacturing. This new form of industrial thinking challenges disciplines such as architectural design to profoundly investigate innovative design approaches and fabrication techniques.
The elective course “Introduction to Cognitive Design and Fabrication” introduced students to cognitive design principles, computational design processes, and additive manufacturing techniques. After learning the principles of cognitive design, students developed their own design that applied these principles to the design of “Everyday Things”. This included, for example, items essential to responding to COVID-19, such as face masks, safety glasses, and face shields. In addition, students were introduced to additive manufacturing techniques such as 3D-printing and robotic additive manufacturing to materialize their design.
This course included two workshops. The first, on computational design, discussed integrative computational tools, such as Autodesk Fusion 360, to sketch, design, simulate, and manufacture a design concept. The second workshop focused on robotic 3D-printing and introduced advanced robotic controls to explore experimental robotic fabrication in design.
