A complex articulated equilibrium in the form of tridimensional curvature patterns is delineated through the interaction between two divergent material behaviors. On one hand the stored elastic energy of stretched textile, on the other hand the stiffness of a thermoplastic polymer distributed heterogeneously through 3d printed algorithmically generated patterns. The two material components form a hybrid system with smooth aesthetic appearance, inherent material efficiency and structural stability. The underlying concept behind tension-active structures is to store energy in the textile material prior to 3D printing and then release that energy to affect the form and function of the hybrid system. A flat pre-tensioned fabric sheet is being 3d printed onto. Upon release, a tridimensional highly dynamic shape emerges. Through the use of digital material behavior simulations as well as large scale prototyping the workshop will bridge the gap between digital and physical and will provide participants with insights into the behavior of tension-active structures. Tension-active structures are relatively easy to fabricate and capable of flat-pack shipping. They are widely used for lightweight and cost-efficient structures ranging from canopies and shade systems in architecture, to acoustic deflectors, light diffusers and decorative elements for interior design or for aesthetically pleasing fashion apparel applications. The rise of 3D printing combined with newly gained capabilities for physical simulations empower designers to program smarter materials which transform and adapt into objects without mechanical devices, bulky components and difficult assembly processes. We find ourselves at the edge of a new episode where technological breakthroughs allow us to create, investigate and imagine a new range of structured forms of matter. This new paradigm entrusts designers with fresh abilities which have the potential to impact industries like architecture, product design, apparel, aerospace or automotive industries.
Tension-active structures have intrigued mathematicians, physicists, engineers and architects for the past 250 years. Their origins trace back to a problem raised by Lagrange that later became known as the ‘Plateau Problem’: finding a surface of minimum area that spans a given rigid boundary curve. More recently 3D printing on textiles has added to the palette of technologies that designers can call upon. The relatively new research area is characterized by the challenge of having flexible boundaries working in tandem with a surface that tends to minimize its area and mean curvature. The workshop will be introducing the principles behind tension-active structures in a fabrication-oriented fashion. The participants will learn how to digitally simulate the behavior in the Grasshopper Kangaroo Plugin. The participants will then fabricate their designs on a large Delta Wasp 3MT 3D printer with a maximum build volume of 1m x 1m x 1m and receive real world feedback for their designs. The students will split in groups of 4 and will start brainstorming ideas. They will be assisted in employing the newly learned principles in digital projects. The fabrication phase of the workshop will introduce students to large scale 3D printing. They will learn about the printer and the extrusion systems, their advantages and constraints, how to prepare fabrication files taking into account the material and they will eventually assist in the 3D printing of a prototype for each group.
