Our purpose is to create a contrast between four monochrome surfaces and a multi-colored surface situated in the middle. In the modeling procedure the four surfaces have a slope which causes a shade and at the same time the middle surface consists of distorted pyramids defined through a Grasshopper definition. The pattern of the pyramids allows different colors of valchromat to show. We created sloped contour lines on the four monochrome surfaces which are parallel to the inner edges. For the multi colored surface in the middle, we created dense contour lines on the pyramids.

Hyperborders

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.

Folding paper/cardboard lamp

The aime of this project was to understand the behaviour of material with folding technique and what limitations we were facing with this material. In our case it was cardboard/paper. Hence with a 1mm thick black cardboard, we created a lamp which explored the possibillityes of structuring with a cardboard. We figured out a way to make a very rigid structure by folding the cardboard in a triangle. Exploring different sizes and we concluded in using the same size of triangles throughout the lamp and making the structure by composing those triangles on top of a solid base holding the light bulp.

The lamp gives a mixture of a direct light and diffused. Being able to see the bulp from some corners

3d Printing – Group 17

Anya — Thu, 05 Jan 2012 02:31:08 +0000

Concept

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.

Valchromat Milling – Group 17

Anya — Thu, 05 Jan 2012 02:18:21 +0000

Concept

The idea was to create a geometrical pattern which can change and be perceived as a different volume from different angles. Leonardo da Vinci drawings were our inspiration. The object consists of 50 mm cubes and in each row the cube touches the adjacent cube in its corner (intersection point) and they have one parallel continuous diagonal line for the whole row. The rest of the rows are the same but it is shifted half the diagonal length to one side to intersect the cubes corners with the previous row intersection points.

Milling strategies
• 2 Axis engraving milling.
• 12mm radius tool.
• Maximum depth reached was 22mm.
• Process took 40 min to finish.

Laser Cut Lamp – Group 17

DIGITAL FABRICATION – LAMP – RIBBING

Specifications
Technique : ribbing
Material: methacrylate
Thickness : 3 mm

Design process
To articulate ribbing as an inverse technique as opposed to outward expression.
To attain fluid forms within a rigid geometry

Joinery detail
-insertion
-grooves and notches

The following were our observations:

Material
1. During the laser process, there is loss of material.
2. Loss of material varies with the speed and power used to laser.
3. The size of the sheet also affects the laser process with larger sheets prone to bulging.

Laser cutter machine
1. The slc gave us well cut, clean edged members, along with crisp engraving.
2. The blc settings were harder to control, with the engraving and cutting resulting in cracked edges and murky details despite varying speeds and power settings.

Technique
1. For a 3 mm thick sheet, a groove of 2.8 mm was the snuggest.
2. The methacrylate sheet is not flexible and is prone to cracking and splitting, more so if it is forced into a groove of a smaller size.

3d-printed Nodes

Sliding Structure

The starting point was the choice of the power that puts the model in motion – this power is gravity. The model slides down a rope and the mechanism converts the energy of sliding to rotate the joints. That’s why we needed to 3d print not only joints, but also the gears. Furthermore we needed to laser cut other details, to make the process more profitable. The joints were produced in the way that the model can rotate infinitely.

Printed details:

Upper joints: 6
Lower joints: 6
45 degrees inclinated gears: 2
13 degrees inclinated gears: 6

Infomilling

Because of the specifications of the Valchromat material, and because we could use different tool sizes we thought that this assignment is a very good way to display information. We decided to display information about laaC students, specifically their origin.
So we placed a worldmap on top of our piece of material. We placed laaC in the middle, and put points on top of the countries where the laaC students come from, then connected these points with IaaC.
We selected the depths of the cuts in the way that, on each “crest” is on a different color level, so circles and straight lines are drawn by colors.

3D PRINTING – INTERLOCKING CURVES

Aim : To design joints for 6mm dia rods to create flexible structures.

Joint 1 –

Two similar boomerang shaped element interlocked within a slit in them forms the first joint. The two elements are free to rotate within the limited axis. Each arm of both the elements can accommodate one 6mm Dia rod. The outcomes of these joints in more number of combinations are unpredictable.

Joint 2 –The second joint is made up of two elements which are unified by a ball and socket joint . out of the 3 arms of the joint , one arm is designned to rotate along its own axis and this is facilitated by the ball and socket joint.

Working of the joints –

Joint 1 -
Joint 2 -

Final assembly of the joints –
