The exercise aims  to understand the various aspects of milling machine, the ability for it to make an architectural detail and to understand its constraints on design.  Focusing on the use of milling tools in order to get specific forms, the exercise was to design a hexagonal tile of size that would be tangential to the points given so as to create a seamless repetition of patterned designs thus the pattern should allow rain water to flow seamlessly in order for it to make its way out of the pattern.

Design:

The concept and the goal of the pattern is to create a seamless flow on organizing curvilinear lines, this is achieved  by the use of different levels of curvilinear pattern linked to each other, it is derived and inspired from a series of abstract patterns that were extracted to study water flow thus from diverse animal patterns seen on different kinds of animals and organisms. This pattern works as rainwater collector diverting excess water to a specific area when interconnected for the reason that each lines are levelled up to bottom, sloped gradient from higher centre of tile to the lower edges. Coming from the middle point of the tile, when channelled to each other it creates a slide through and through, so that water are collected into a specific area. The extruded lines also creates a rough surface that has the capability to trap dirt, for safety reason the pattern is designed as a non slip surface.

Process:

The process initiated various curvy linear lines within the hexagon and whereby understanding the flow patterns, further this lines arranged at different levels to get a clear idea of water flow, then with the help of 3d modelling various curves were examined and its flow were studied. This patterns were tested with the help of CAD-CAM stimulation and milling tools, giving a clear idea of actual formations. Hence a final prototype was derived through it and milling G-Code were exported. This G-codes were feuded in milling machine. The milling was done on 50mm Thick Styrofoam. Through intensive milling, a foam mould for casting tiles was produced. In order to cast a concrete tile the mould surface was finished with Vaseline so that the concrete won’t stick to the mould and multiple tiles can be produced through single mould. Further it was poured with concrete and dried for 12 hours. The tile was taken out from the mould and settled for another 12 hour in order that it is completely dried out. The process was repeated and multiple tiles were casted. The Vaseline on tiles was cleaned through water and finally tiles were dried and polished.

Renderings:

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.

As the purpose of the exercise was to create tile pieces to cover the school’s patio floor, we decide to create an image concept to represent what we think is the essence of the school and the advance architecture at Iaac: The students.

That’s why we decide to create “Topography Faces”, a trilateral symmetry design that represent thinkers of the new architecture.

With 3 diferentes face designs in 3 different corners of the tile, the design becomes a complex pattern formed by the rotation of the title to match with the next face and finally forming a topographical surface for water flow.

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.
