The idea to inject a fluid material to build underground structures like docks or pilotis in dunes is not new in architecture or engineering fields. This techniques using sand within a frame of a static and a rigid casting process where the way to inject the material is just to fill a hole drilled before.

We think that we can innovate injecting a fluid and structural material into sand using capillarity as a parameter to emerge a potential new geometry. Our intuitions are related to use sand as a medium to generate  this new geometry instead of a cast.
From a theoretical point of view, the specific material behavior injected is directly related with the sand capacity to absorb it by capillarity. This phenomenon in physic is called as sorptivity.

Through this, we think that we can generate an emergent geometry controlling the specificity of this phenomenon.

At this moment we know by facts that the best idea to inject into sand is to build a machine with a very thin nozzle in order to avoid the natural pressure of sand through the process of dig and do not waste energy.  In the same terms, use a low viscosity material is fundamental to achieve a sustainable process.

According to this, the  parameters of time_speed of the injection, angle of the nozzle and the viscosity of the material are the most relevant data that we need to provide the machine in order to control the potential emergent tectonic through computation.

Our first thought was how to use the movement as a source of information and interaction with a machine.
We decided to use a color as a source of interaction and real data creating an image of this stimulus on a physical result.
The idea was to hack a printer and a CD writer to achieve 3 axis of movement.

Basically, the machine works with 4 main steps: IMPUT_color stimulus,  CAMERA-Screen_to identify the movement, PROCESS the information and RESPONSE on a physical result. This physical result was an expression of the movement stimulus with allows us to use this machine to create different patterns of expression.

Generative Design

The aim of the processing with Thiago Mundim we managed to simulate the sand`s behavior. The definition resulted in the visualization of a

nozzle collecting sand particles from a point and a second nozzle  depositing them in another point.

Also in a bigger scale it was necessary to simulate the movement of a double nozzle autonomous machine to define its possible trajectory so that

it never steps on what it did. The coordinates of the movement and the deposition points are exported to a txt format available to be used by the

milling machine. The green circles are the piles of sand and the red, the holes (negative) created to the points from which the sand is collected.

Influenced by an autonomous-deposition machine we started speculating about a mechanic fabrication on-site using the site`s material (sand).

The task of the machine is to re-arrange the existing surfaces by collecting from one node and depositing from the other, piling sand. Once the

surface is arranged glue is poured on strategic points of this surface. The choice of the points (coordinates) are yet to be discussed as it is an important

parameter of our fabrication process.

Trying to deal first with the deposition issues we hacked the milling machine (shopbot) to simulate in small scale the movement of an autonomous

machine. We simulated the movement of a double nozzle machine with a processing definition, extracted the movement`s coordinates and sent it to

the shopbot.
