Valchromat Milling – Group 17

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

Milling Information

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

Team : Hunia tarck tomoum,Yaping chen & Jayanthimala Thangarajan Gokulraj kailash

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 –
