Brief of the exercise:

The exercise was to design a famous Panot hexagonal cement floor tile as designed by Gaudi in 1904.One of the particularity of this design was supposed to be the capacity to be inserted within a larger assembly and to create continuous patterns across several tiles.

Concept:

When it comes to the notion of continuity within an assembly of tiles repetitive look of the whole flooring sometimes becomes mundane, so to break this repetitive laying was the major concern along with the channeling of water on a surface which should be controlled by the level difference within the pattern. And even in water channel the intent was to achieve the water flow which gives the sense of surprise in the journey.

We started with the idea of illusion. We thought of creating an effect of crack. This gives us random look in the overall flooring even though the tiles are of the same pattern. We wanted to surprise the user while walking on this tile, thus by illusion of crack and randomness in the flooring we can always make user to look at the pattern.

 Execution:

To achieve the end result we used 3d software to simulate the pattern. We used the plugin where particles are collided to the surface and it gives various patterns. This collision can be controlled as per the expected end result.

Then we used rhino cam(plugin for rhino) where we defined the strategies for the milling process of the mold. We used two ball mills, 12mm for pen for the carving of the mold and 3mm pen for the final finishing and engraving. Once the molds were ready we applied four layers of sealant at interval of 15 minutes to dry and then wax before pouring concrete into the mold. Each time took 12 hours to dry.

After getting all the tile we cleaned it with hot water to get rid of extra wax and then it was ready to lay cracks all over the place.

When designing the pattern for our tile, we examined the behaviour of raindrops, and the effect they have when hitting the tiles of Barcelona.

Creating ripples in the concrete, we duplicated the intricate patterns of the raindrops within our design. These patterns flow through the four tiles that we created. Using a variety of larger and smaller scale curves, these spirals join together to form one continuous pattern.

This liquid surface was then imported into RhinoCam where it was adapted to the form and dimensions of the tile. RhinoCam was used in order to create the spiral effect on the tiles surface.

Once this stage was complete, the milling process begun. From the produced mould, we then filled it concrete and allowed it to dry, resulting in four intricate tiles.

In the final process, we experimented with various ways to polish the tile by applying wax, oil, polish and a brush. How ever it was through these tests that we discovered the harshness of the brush, which ultimately warped and concealed the spirals on the surface.

When connected, the swirls on each individual tile join, in order to create the allusion of ripples with in the ground.

Chameleon Tile

Сlick to see the process!

Our inspiration is simple, since we are in the city of Gaudi, we chose one famous work of Gaudi in Parc Guell : the Chameleon.
And because of the shape of the tile we are going to make is in hexagon,
we tried to achieve a design that comprised of continuous lines and shape, for the tile to be able to rotate to connect with another around.

The design process started with mirroring, rotating, and tracing the above picture to create a circle-like, head to tail, chameleons badge.
Then we used a plug-in called “pointreconstruction” in Rhino to give the triangular texture throughout the design.
The plug-in easily grasped the corners and edge of the Chameleon and create “Delaunay” out of it.
(The process of altering the height of each vertices is very manual and we hope we had more time to study the easier way of doing this)
Anyways, we finished off the design by connecting those water channels in the mold with our branches behind our stars.

The RhinoCam process finally finished .
Then came the job of the milling machine. The mold was done with foam block and consumed about half and hour time each.
We brushed the inside of the mold with thin layer of vaseline. Mixed the concrete. Poured it into the mold.
Shake. Get rid of the bubbles.
Waited for 8 hours to dry (very depending on the temperature and the weather)
Gently twisted the mold and the tile came off easily.
All these processes were very time consuming and we need to work well as a team.
The milling machine also needs a very precise and correct type of strategy.
We also learnt that the concrete work is not easy.
It turned out to be a very delicate work compare to the work on computer.
