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).”
— Who is afraid of formalism?, Sanford Kwinter.
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.

[non-standard] Mass Timber Architecture
“Technology is the answer, but what was the question?”
— Cedric Price, 1966.
Description
This studio focused on ecological construction to explore the potential of mass timber technologies to address new and growing climate change threats. It introduced students to applying the process of design to the construction of mass timber systems. Using mixed-reality technologies, students developed a co-design framework to shift from material- and fabrication-centered design processes to human-centered design-making. They were directly involved in the entire process, from design to construction. The aim of this research studio was to develop [augmented] robotic fabrication to construct experimental mass timber structures at the school of architecture.
This studio aimed to introduce students to mass timber design in architecture. It included four phases: 1) wood science, 2) wood processing, 3) wood construction, and 4) mass timber system design. In wood science, students learned wood anatomy and related physical and mechanical properties of wood, such as hygroscopic and anisotropic behaviors. In wood processing, students were introduced to wood manufacturing of mass timber systems such as cross laminated timber (CLT), glues laminated timber (glulam), and nailed laminated timber (NLT). Through a series of case studies, students explored wood processing such as lamination and connections to generate spatial wood tectonics.
In wood construction, students examined different construction techniques such as CNC milling and robotic fabrication to prototype small-scale timber systems. In the final phase of this studio, students designed a building element. The envisioned elements were 1) an abstracted skin or wall system, 2) a tower or a column as a structural element, 3) a vault or a shell as a roof system, 4) a hut or a shed, or other invented building elements. This one-to-one timber structure was designed for Campbell Hall’s North Terrace at UVA.
Students also explored design space as a parametric space through a parameter-based framework. The computational framework geometrically differentiated and parameterized timber wood structures. This framework integrated the fabrication constraints and material characteristics as generative drivers. Students learned advanced robotic controls to understand the role of fabrication agency in timber construction. They applied additive and subtractive robotic fabrication to develop a tectonic connection between timber elements. Students collaborated in fabrication and assembly processes through mixed-reality (MR) technologies to apply their design intention in real-time. Students applied these three methods to prototype scaled models which enabled them to understand the augmented process of design-to-construction of a one-to-one demonstrator.

Selected Project
Robotic Serpentine Wall
Description
The project “Robotic Serpentine Wall” investigates new, unexpected uses of wood to construct an inhabitable structure. It created a structure that 1) celebrates steam bending’s ability to radically change wood’s structural potential; 2) is inhabitable, improves the site on which it was built, and is connected with the history of its larger context; and 3) was data- and mathematically driven.

This project responded to its site—the North Terrace of UVA’s School of Architecture—in two ways. First, it negotiated the step between the ground and the top of the planter box, a distance of 26 ½”, in a way that encourages small group interactions. Second, the form responds to the complex history of serpentine walls at UVA. This sinusoidal shape was manipulated to create a structure that produced a small gathering area on one side and a seat on the other. It was then reverse-engineered to minimize the number of unique components upon construction.
Several experiments were conducted to test the amount that pieces of birch plywood and oak plywood reverted to their original shape following steaming and either bending or twisting; birch plywood performed better in both. A third experiment determined plywood pieces needed to be a minimum length of 24” to prevent cracking as a result of twisting.
Prototyping the structure led to the discovery that the primary pieces work in tension, not compression. This in turn resulted in the inclusion of additional support pieces for greater structural stability.
The final design was constructed through a complex process of cutting, twisting and bending, and slotting the pieces together. Each piece was machine cut according to the specific measurements dictated by the digital design. They were then steamed before being twisted and bent into position, allowed to dry, and put together. The final assembly process revealed that the connections between wall sections were necessary for the structure to be free-standing.
This project was awarded the 2021 Bruce Abbey Technology Award. It was featured on the University of Virginia School of Architecture’s website.

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.
