The central theme of the project was to create a structure that arose from a flat plane into a three-dimensional object while challenging the properties of the materials used.

The uniqueness of the structure lies in the individual strips that lift from the flat surface, requiring no joints hence forming smooth curves.

The structure evolved over time to its final result where the support members were shifted from the exterior to the interior. Also a few curves were detached from the end strips in order to break the monotony of the overall structure.

Furthermore the strips created evolved from being just horizontal strips to multi directional curves using the laser cutter to our advantage.

Although the bending was done against the grains of the wood we were able to achieve the required result by laser cutters precision to create small perforations onto the surface.

To allow further bending of the wood, it was bent while wet. The inner structure was then fitted to hold the bend in place.

Through this process, it was possible to bend the two strips to achieve a gap of more than 15cm between them. Various distances have been used along the entire model that makes the overall structure more dynamic.

Additionally as the whole board was used to create the structure not much waste was generated from the process.

THE PROCESS:

1. Laser cut the perforations perpendicular to the curve required.
2. Wet the board for about 2minutes either by spraying or soaking (both methods were tried and gave positive results)
3. Bend the curve to the distance required and hold in place for a few seconds. Insert the central structure that would hold the bend while the structure dries and also as as the spine of the model.

Triagon is a combination of triangles and a penthagons coexisting in the same structure.

The goal of this first Digital Fabrication project was to build a tower out of 4 board of 3mm plywood while exploring the properties of the material and to acquaint ourselves with laser cutting.

The Triagon stands 2.7m tall. The structure is made out of a single 180° twisted plywood elements which works in tension along with the joints to form an equilateral triangle which is the basic unit of the tower.

We began with triangles as the basic geometry of our structure because of its stability. After inicial testings of the possible joinery with cartboard and plywood we realized that a combination of circles and rods would be the most efficient design for our conections.

Later on we wanted to play with the properties of the material, so we started bending and twisting the rod, which generates stress on the joints and makes the basic unit more robust. In order to twist the rods 180°  we had to use another technique which involved wetting the plywood so that it became more elastic and cuting inside the rod a dentate form with circular ends to prevent breakage. We also found out that rods needed to be cut in the same directions of the fibers so that the twisting could be achieved.

To minimize the waste of the material and the cutting time we used just 2 elements in the whole structure, one was the 30cm rod itself and the other was the circular conections which we also used for attaching the tower to the base.

The whole structure is assembled of equal triangular bending modules. The modules are using the orientation of the wood’s fibers to enable small radii. The bending’s direction is perpendicular to the fibers’ direction, which means that we are not working against the material and the whole structure gains rigidity. 

Another manipulation that we have incorporated are the vertical holes in each module- we have experimented with their distribution and length in different stages of the project in order to control the flexibility of each piece. There is a circular hole at the end of each “crack” to prevent them from spreading and breaking the geometry.

The levels are created by piling up 4 interlocked modules. The freestanding structure gained a tubal shape due to the vertical repetition.
