016 – PNEU-SKIN: A Haptic Social Interface with Inflatable Fabrics
Wednesday 31 March, 14:00, Session 6B

Marcela Godoy, New York University Shanghai
Wearable electronics endow us with a great capacity to see clothing as an extension of our body and an interface to interact with our physical and social environment. The fashion industry is experimenting with new tectonics, and materiality, however, few projects have explored wearables in the public and social domains and how they can dynamically respond to a wide range of interpersonal distances in social interaction. PNEU-SKIN is a pneumatic wearable that uses critical making as a research strategy to explore interactive and soft interfaces to create soft boundaries between private and public space. This paper proposes an embodied computation agenda and describes the design and prototyping process of a multi-sensory smart skin in response to varying social distances in interpersonal communication. By looking at adaptive behaviors in nature and the way that certain animal species respond to external stimuli by increasing their size and providing multi-sensory responses, PNEU-SKIN looks into how our clothing could become an adaptable skin to redefine interpersonal communication experience within everyday social interactions.

262 – SISTEMA NERVI: Sustainable Production of Optimised Floor Slabs through Digital Fabrication

‘Sistema Nervi’ (the Nervi System) invented by Pier Luigi Nervi greatly economised the production of complex concrete forms optimised in both material usage and structurally. However it did not translate well into other contexts due to labour and material considerations (Leslie, 2018). This paper explores novel methodologies of producing optimised floor slabs and concrete structures, using digital fabrication techniques, focusing on both labour economisation and sustainability principles. A module from the Australia Square lobby slab has been used as the set geometry and was reproduced using differing techniques of fabrication for a comparative study. The study was conducted at scale (1:20). The viability for production at full scale (1:1) for manufacturing is discussed. The assessment criteria for the tests are divided into four categories: Cost, Time, Performance, and Sustainability. 3D printing of PLA plastic and ceramic clay extrusion printing has been used to produce removable or degradable formworks. These technologies have been selected due to their current market availability and associated costs. This study hopes to introduce improved methodologies for producing optimized concrete forms, as well as the sustainability potentials of a degradable formwork such as ceramic clay. Both systems were ultimately able to produce workable formworks for optimised shapes and showed promise for reducing labour involved as well as presenting with material sustainability for discussion.
This is my first published paper and it was my Honors Thesis for my Masters of Architecture. I finished university in 2020 and am starting my architectural journey in Sydney Australia. I have a keen interest in advanced construction, parametric design and environmental sustainability. These interests form the cornerstone of my paper and have helped me to develop as a researcher and Architect.
179 – Graded Knit Skins: Design and Fabrication of Curved Modular Façade Cladding Panels
Wednesday 31 March, 14:30, Session 6B
Ying Yi Tan, Singapore University of Technology and Design
This paper presents the design and manufacture of lightweight membrane panels using a textile-rod system composed of bespoke multi-material knit membranes and bending-active rods. These two components come together to create cladding panels of non-standardised curved geometries. Moreover, this paper will explore how these two components can be designed to provide geometric control over the shaped panel. It will also demonstrate how these panels can be made into a modular system through the assembly of a 2×2 panel prototype.
Ying Yi is a recent PhD graduate from the Singapore University and Technology and Design (SUTD). His research investigates the design and manufacture of bespoke machine-knitted fabrics for architectural applications. Furthermore, he is currently working with several inter-disciplinary research groups in SUTD to explore how CNC knitting technology can be applied to the domains of mechanical engineering and wearable sensors.
250 – Min-Max: Reusable 3D Printed Formwork for Thin-Shell Concrete Structures

This paper presents an approach for reusable formwork for thin-shell, double-sided highly detailed surfaces based on binder jet 3D printing technology. Using binder jetting for reusable formwork outperforms the milled and 3D printed thermoplastic formwork in terms of speed and cost of fabrication, precision, and structural strength against deformation. The research further investigated the synergy of binder jetting sandstone formwork with glass-fiber reinforced concrete (GFRC) to fabricate lightweight, durable, and highly detailed facade elements. We could demonstrate the feasibility of this approach by fabricating a minimal surface structure assembled from 32 glass-fiber reinforced concrete elements, cast with 4 individual formwork elements, each of them reused 8 times. By showing that 3D printed (3DP) formwork cannot only be used once but also for small series production we increase the field of economic application of 3D printed formwork. The presented fabrication method of formwork based on additive manufacturing opens the door to more individualized, freeform architecture.

282 – Digital Fabrication of Growth: Combining Digital Manufacturing of Clay with Natural Growth of Mycelium

In this paper we will demonstrate that a digital workflow and a living material such as mycelium, make the creation of smart structural designs possible. Ceramics industries are not as technically advanced in terms of digital fabrication, as the concrete or steel industries are. At the same time, bio-based materials that use growth as a manufacturing method, are often lacking in basic research. Our interdisciplinary research combines digital manufacturing – allowing a controlled material distribution, with the use of mycelial growth – enabling fibre connections on a microscopic scale. We developed a structure that uses material informed toolpaths for paste-based extrusion, which are built on the foundation of experiments that compare material properties and observations of growth. In this manner the tensile strength of 3D printed unfired clay elements was increased by using mycelium as an intelligently oriented fibre reinforcement. Assembling clay-mycelium composites in a living state allows force-transmitting connections within the structure. The composite named “MyCera” has exhibited structural properties that open up the possibility of its implementation in the building industry. In this context it allows the design and efficient manufacturing of lightweight ceramic constructions customized to this composite, which would not have been possible using conventional ceramics fabrication methods.

Coming from the tradition of a 100-year-old family of teachers, the personal examination of material properties and technologies arises early on him. The father as a visual artis shapes and opens a free choice for the educational path. The choice of higher artistic and technical training at the Ortweinschule Graz sharpens the ceramic way. After graduating from high school, attending the master’s school enables him to complete his trade with the master’s exams. State school as a ceramic technician in Germany provides comprehensive ceramic education for technical implementation as well as for teaching.
