The Area.

The Institute of Advanced Architecture of Catalonia is involved in a research project to transform the city of Barcelona in a Zero Emission city.

For that, an interactive model has to be fabricated, so design decisions can be made. In this tutorial, we will describe the step by step of how to send the 3D model of the barrios of Camp del’Arpa, La Sagrera, Congrés and Navas, to the milling machine so it could be milled.

After the model was printed in a high density foam, it was inserted in the model of the entire city of Barcelona. The scale of this model is 1/2000, and it will be used as a study model. A final interactive model will be built, and this will help in the design decision.

Concept:-

Our 3D Print Brick pattern is inspired from the structure of a honey comb. However, the rigid hexagonal shape and the uniformity of the honeycombs have been modified integrating it with other polygonal shapes. These modules are varied in size and intensity to resemble a spider’s web. The idea was to read the voids as much as the solids akin to the Zaha Hadid’s ‘Mesa Table’ which was one of the case studies undertaken. To achieve a more organic form and to avoid rigidity, the surfaces have been gently curved.

Procedure for 3D Modelling:-

Step 1: A single line polygonal pattern was drawn out which formed the basis of our 3D modelling. This was done by marking random points on the opened up surfaces of the brick. Using ‘Voronoi diagram’ a pattern was drawn out. This pattern was modified and redrawn to achieve the required density required to balance out the solids and voids & to realise the spider web-like effect.

The Objective

The Aim of this exercise was to create a foam model of the barrios using the CNC Milling machine and learning the milling process.

The Process

Step 1: The zone assigned to our group (Horta Guinardo-Nou barris) consists of two hills and a mountain on the north west so we first prepared the terrain in rhino.

Step2: The buildings and the streets were projected onto the terrain.The building footprints were set to a plane at the lowest point of the respective building for the purpose of vertical extrution(using setPt command).

Step3: The building were extruded to their exact height using the data from Internet.

Step4: As it was not possible to print the mountains with the remaining barrio the mountain and hills were separated from the model to be printed later.

Step5: The file was made ready for printing and divided in two parts in order to fit in the foam sheet.

Step6: The Model ( without mountain and hills ) was printed on the CNC Milling Machine.

CNC milling

Sub Step 1: Fixing the sheet on the base.

Sub Step 2: Loading file on the Interface and running.

Sub Step 3: Vaccum cleaning the sheet.

Step7: The model is cut at the boundaries and cleaned using sandpaper.

Step8: To print the mountain and hills with the buildings on it.(Pending)
