Barcelona Port is in the edge of the city where different flows and fixities coexist together. The suggestion that different footage took from the port gave to us was the notion of the border. Boundaries or limits are part of the natural and urban composition that could be considered as negotiators between elements and actions; flows and fixities. The perception of the border is predominant in a port. Besides the idea that a port is the limit between the water and the land, it also means political, urban, social and economic boundaries.

The concept of the first approach we developed from the site was a visual record of all the type of limits we found in the port. The waterfront is a limit between the land and the water that has been shaped through the time. Also we found important to refer Kevin Lynch description of borders: “Borders are linear elements

not used or considered as paths by the observer.They are the boundaries between two phases, linear breaks in the continuity. These border elements are for many people importan organizing featureas, particularly in the role of holding together generalized areas”. For us, this concept is very important in order to understand the image of borders that cities have and maybe rethink it.

3d Printing – Group 17

Motion was the main theme in the printed object, and aim to create a dynamic representation of the space. The idea was inspired from the mechanical (reciprocating) engines and the sequential movement between engine parts (cylinders and rods). The object consists of five joints, two different types, and ten steel rods. Moving one of the rods will cause the middle cylinder to rotate and to move the whole system.

Descriptions :
Type 1
• 3 pieces; one cylinder 18mm, two connecters one each side, two cylinders 12mm.
• 36 mm width.
• 30.6 mm height.
• 12 mm movement range.
Type 2
• 3 pieces; one cylinder 18mm, one connector one slot, two cylinders one with connector one with slot 12mm.
• 40 mm width.
• 30.6 mm height.
• 16 mm movement range.

3D printed joints

How to make a joint for a movable structure?

The design of the articulation started having as a case study the above working model.The joints were designed in order to serve specific movements which will provide the required mobility in the construction.
In order to have full movement, the construction require 12 articulation.
The essential function of almost all the joints is the rotation round an axis. This axis, and the union, are connected to the basic unit on which we can find connected maximum three related extensions.
However it could not be given the necessary mobility in construction if had not designed a central articulation. It’s basic function is to retain the overall grid. In this case the metal bar did not articulate but glide through the joint.

DIGITAL FABRICATION ::: EXERCISE 2 – Valchromat milling ::: GROUP 19

Inspired by Sand dunes formation and its patterns.

Horizontal Roughing was important to be done prior to the 3-axis Projection Pocketing in order to save time.
The whole process in total took 1 hour.

3D milling – Process consisted of two phases:

First phase:
horizontal roughing
Tool: BallMill 26mm in diameter
Dimensions of the board: 600 by 400mm
Boards of 8mm thickness
Time taken: 9 min.

Second phase:
Projection Pocketing following a rectangular path
Tool: Ballmill 12mm in diameter
Global parameters intol: 0 , outtol: 0.4,
% Tool Diameter: 25 %
Time taken: 48 minutes

Rhino file: steps of formation

Horizontal roughing
