The milling process has been evaluated with three different ballmills: a 12 mm diameter one to remove material, a 6 mm one diameter to mill the designed shape and a 3 mm ballmill to finish the outputs.

Once the mold was finished we applied 4 coats  of sealer and let it dry. Then we applied a layer of vaseline so that the cement did not stick into the mold. Next step was to pour a mixture of cement, water and additives. The mixture dried for 8 hours. After taking the piece out of the mold, the surface has been cleaned out of the vaseline and the oil has been applied to uniform the finishing.

To be continued… (once we have more tiles) 

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.
