INTRODUCTION Inspired by some metal aggregation studies, we started our research and design from the simplest geometry---cone, which has the advanteges to rotate at any directions and can break or grow at any branches. For the material reseach, with the aim of finding strong but lightweight haderning method, we use the most common construction material----concrete by mixing it with other plaster materials. Basically, we aggregate our components by making cones into curves first, then combine them according to the digital form-finding outcomes. After that, we applied concrete on it to harden it.

INITIAL APPROACH At the very first beginning, we were inspried by some aggregating art works by various artists or architects, such as Neri Oxman, Iris Van Herpen, Tobias Stenico, Jose Sanchez & Alisa Andrasek.

We were rather interested in the aggregation of simple compnents by arraying and stacking, in order to create some interesting patterns like spiral growth. Starting from the references, we tried to make some small physical sculpture by simply cutting and folding metal sheets. With these easily-made cone shape components, we used stacking and arraying to connect cones.

[ Component Aggregation ] Inspired by the patterns in the artworks of Neri Oxman, Iris Van Herpen and so on, we were interested in the aggregation of simple compnents by arraying and stacking, in order to create some interesting patterns like spiral growth.

CHAPTER

FABRICATION RESEARCH In this chapter, we focus on the material tests and fabrication method. Starting from comparing different materials property to make a simple cone shape, we found the aluminium mesh is very lightweight, strong, flexible and its surface make it easy to attach to hardening material. Then we researched how to fabricate it manually and machanically. After that, we compared with different kinds of concrete to harden it.

[ Geometry Study ] We study three basic geometry shapes which are triangular base pyramid, rectangular base pyramid, and a simple cone. Both of the pyramid shapes allows more surface of connection, make it more easier to join side by side with another components. However the cone shape make it possible for 360 degree branching as well as create a spiral pattern when stacking linearly while the pyramid shapes with surface cannot.

[ Material Properties ] By comparing a wide range of materials, such as papaer, plastic sheet, felt sheet, aluminium sheet, prepreg carbon fiber and aluminium mesh, by its properties, deformability and price. We found the aluminium mesh is the best material for its flexibility, stability and ability to attach concrete.

[ Mass Manufacturing Potential] A single chair may need hundreds of cone components. So it is an urgent task for us to find a faster, cheaper and more convenient way to producecones. We tried to use water jet cutting machine for its preciseness.

Laser Cutting

[ Cone-making Options ] Making a cone is easy, just need some simple tools, like scissors and hands, to cut it along its mesh, and roll it around some moulds, like pencil or cone-shape objects. If more preciseness is required, we can use the water jet machine to cut it.

[ Coating Strategy ] We study diferent materials to apply on the surface of the aluminium mesh component in order to test which material is the most suitable to make each component connect together. As a result Polyurethane rubber is the most stable because it can bond and connect the Aluminium mesh very well.

PART 2: BRANCHING SYSTEM

[ Generation Process ] An L-system or Lindenmayer system is a parallel rewriting system and a type of formal grammar. An L-system consists of an alphabet of symbols that can be used to make strings, a collection of production rules that expand each symbol into some larger string of symbols, an initial â&#x20AC;&#x153;axiomâ&#x20AC;? string from which to begin construction, and a mechanism for translating the generated strings into geometric structures. L-systems were introduced and developed in 1968 by Aristid Lindenmayer, a Hungarian theoretical biologist and botanist at the University of Utrecht. Lindenmayer used L-systems to describe the behaviour of plant cells and to model the growth processes of plant development. L-systems have also been used to model the morphology of a variety of organisms[1] and can be used to generate self-similar fractals such as iterated function systems.
