Group 15_ Milled Collage

By deniz.tumerdem@iaac.net | Published: May 28, 2012

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.

Folding paper/cardboard lamp

By hulda.jonsdottir | Published: March 20, 2012

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

By Anya | Published: January 5, 2012

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

By Anya | Published: January 5, 2012

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

By Anya | Published: January 5, 2012

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.
