The Lotus Flower it’s a kinetic and dynamic structure.

The goal of the exercise was to producing 3d printed pieces and explore the design opportunities arising from the potential and limitations of the technology to create a dynamic assembly with 2mm diameter rods linked together by 3d printed pieces.

Our idea was to design just one joint. This joint should had the capabilities of generate through the connections between themselves and with the help of the elastic nature of the tubes in order to form two geometrical moments, one that’s goes up and another one than goes to the sides.

The dynamic nature of the joint allows a level of movement between the rods themselves in a translation system by moving the rods in to a circle to move within itself and transfigure into a bigger or smaller structure.

The project consists of simple joints and their response to the stored energy inside the rods. Playful. The rods stay in form with the already stored energy and if you touch and release the energy it “explodes”.

The explosion does not make the installation irregular, but it makes it back to its ordinary geometric form. This explosion does not mean destruction and irregularity, it brings silence and order to the geometry.

In the design process we aimed to experiment with different types of assembly. Each rode finishes with a sphere which arrives to a central assembly point.

The “gathering” joint’s outline is shaped in a way to have all the spheres inserted and let them move in all directions. Additionally, underneath the board (standing on 2cm blocks) there are wheeled-joints allowing the rods to move on the surface. The rails cut in the board are keeping the pipes in the assigned tracks.

The structure changes from a tightly angled curves with a lot of tension and stiffness to more loose hyperbolical shapes, which rigidity is kept because of a refined twist at the base.

The joints were designed to take advantage of the 3d printer’s ability to create small, yet detailed 3-dimensional objects. Each joint has multiple holes to allow rods to fit in 8 different directions.  The dynamic movement of the structure resembles that of a curtain. The structure can take several forms by sliding the joints through the rods: the looping (side) rods slide along a central rod arc. The transition exposed in the photo overlays is between two basic positions: one where the side rods are lying flat on the board and one where they form a full scale volume following the arc.

We created joints of 3 different sizes. Each of the two largest joints connects half of the side rods, so that they are able to rotate from a common point, whilst the smaller joints fix the ends of the rods, allowing linear movement along the arc that passes through the central joint channel.

Printing on the z-corp machine (composite powder) limited the joint’s strength, so further experimentation on possible forms was challenging due to the joints breaking, but nonetheless, we discovered the component’s tension thresholds and exploited its capabilities.
