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 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

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 –

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.

Joints for eqilibrium

We part from the idea of recreating a structure that can move and stay in equilibrium as easily and as gracefully as a Calder Structure. These sculptures allow for a great deal of movement, and work perfectly in equilibrium, continuously stabilizing itself.

We devised a joint that allowed us to take the Calder system a bit further. Our new joint is able to hold as many as 18 rods at the same time.  It rotates elliptically and vertically, allowing the structure to “find” its own balance according to where the rods are placed and where you apply force of movement.
