RC6 CRAFTING SPACE
SPACESTREAM Mengying LI, Zhen SHAN, Wenjian YANG, Shaoru WANG
Starting with a brief introduction to the design project, SpaceStream is a project of Bartlett AD Research Cluster 6. Under Daniel Widrig’s guidance, the design project brings focus on the combination of traditional, hands-on crafting with advanced computational, technological tools to create or realize new construction methods and processes. In fabrication research, it can be figured out that how the process and the method inspired from non-traditional materials are not utilized being a part of building but as the medium during the design process. Concretely, SpaceStream aims to explore a design system by using light weight materials and the method of casting to make a strong spatial structure. Wax is initially introduced as a main role because of its character of flexibility and the traditional lost wax casting techniques. It is easy to be formed and lost in further casting process. Whereas on the other hand, the free form of wax is too difficult to control due to this kind of flexibility. Thus a wireframe system using straws is imported in to work together with wax. Straws are used since it is easy to access and can be burned during the casting process. By dipping straw structure into melted wax, a thickness difference would be applied onto the straws. In the next stage, the combination of both straws and wax could be casted into a strong and controllable structure . Furthermore, before combining with wax, the straws system is also a great tool for small scale structural exploration. We

have both basic structure research and design products made by straws. In digital research, this project focus on demonstrating how Rule-based Digital Modeling affect crafting work in architectural design and the way it helps to increase working efficiency. Generally, there are five design language systems in SpaceStream project generated from straw studies. They are Geometry System, Grid System, Lifting 2D to 3D System, Surface System and Bundle System. All of them have certain principles of building up the language system, which are the bases for further digital modeling. To sum up, considering all the introductions above, the whole process of crafting work is very important as a premise to the following discussions about Rule-based Digital Modeling and a source which rules are extracted from. Correspondingly, based on the five systems, digital feedback can respond to and interact with crafting rule, in which way we could further improve existing crafting principles as well. As an advanced version of Computer Aided Design, Rule-Based Digital Modeling has brought numerous opportunities to architectural design. It is affecting architectural design from all aspects, especially the tremendous contribution it made to enhance the efficiency of complex construction crafting working. After getting feedback from digital modeling result, The new effects happened on simple materials but to affect the perception of space in new ways.

and flexibility. Wax is a common material used both in daily life and industrial manufacturing. It comes in several types which all have their own characters. Also, by the method of lost wax casting, it is easier to be converted into strong material. Soda cans are made from aluminum which is a type of light metal and has lower melting point. Cans could be obtained from recycling and very common in daily life.

In this project, some daily, simple, untraditional construction materials are utilized to make a spatial structure. By lost wax casting, straws, paraffin wax and soda cans are converted in to a strong metal structure system.

[ Introduction ]
The 5th design language is called inflation, it is based on the appearence of wax thickness. The inflation effect can be applied on the parts that need to be strengthened on the model. According to the load analysis, parts that bear more are often located in the inner part of the model. Considering the dipping method of applying thickness, it is farely difficult the maker inner parts thicker than the outskirts.

[ Introduction ]
To replace inflation system, we designed another system called the Bundles. Simplly duplicating the amount of edges at the same position, the bundle system could make certain edges of the grid looks thicker, which has the same effect with inflation system but no constrains from wax.

Welding with Templates The basic geometry used in SpaceStream Project is made of 6 squares or 8 triangles. A template is designed to hold these 2D patterns to help welding half of cuboctahedron. These half geometries are made for whole cuboctahedrons in the next stage.

Detached Pieces Fabrication Process As each detached pieces of the chair is made based on the basic geometry -- cuboctahedron, it is easier to make them by removing edges from the geometry. Its relationship to cuboctahedron is also the bridge to comunicate with other welders who helped us in the initial fabrication process of SpaceStream.

[ Different Types of Detached Pieces ]
The detached pieces can be divided into 3 types which are pyramid - based pieces, 2D flat pieces and Cuboctahedron - Based Pieces. The overall shapes are different but they are all based on the Grid System and can be cut from a cuboctahedron.

Architectural Design
Architectural Design This section includes two architecture designs in different scales, a pavilion and a house. In this design process, the former design language needs to be developed to apply to more complex structures. For example, except the former design about vertical structru such as staircase and columns, the plane structure like wall roof and floor also need to be dissolved. Based on that, synthesizing different parts and creating a completed design system is the destination of the project.
