Deployment

Origami is the ancient art of transforming a flat piece of paper into a variety of 3D shapes by simply folding along a pre-set crease pattern.

Geometrie

The aesthetics and effective deployment of origami folds is an interesting direction to investigate.

Deployment of a horn

For the deployment of a horn:

• Shape memory polymers are distanced because their expensive price.
• Shape memory alloys are distanced because I think they are not appropriate for the expansion.

Design & Fabrication

From the book of SPIRAL Origami Art Design by Tomoko Fuse, I folded a paper whirlpool spiral (5|10|31) from a crease pattern produced from Rhinoceros software. The paper advantage is its thinness to make a very flat stack despite the number of layers. To realier the crease pattern, I followed the Inkscape Tutorial: Drawing Origami Crease Patterns for Whirlpool Spirals.

How to trigger the increase in height between each polygonal floor ?
Actuation test: Shape memory alloys
I knew it wasn't going to be the method chosen but I tried it to see the "power" of relaxation after contraction.	via GIPHY
Actuation test : electromagnetism
I was thinking of using the repulsion between 2 magnets to trigger the deployment of the spiral and therefore using an electromagnet to trigger it. It's a failure, there is no repulsion. However, I could use the electromagnet to get rid of something for my project.	via GIPHY

Design & Fabrication

3 tests for silicone wrinkling: silicone with embedded nylon muscles, silicone with embedded nylon muscles in the deep layer and inclusions in the surface layer, silicone with canals in the deep layer and inclusions in the surface layer.

The artificial muscles are thermally driven actuators that can be triggered by applying voltage across terminal, similar to shape memory alloy	via GIPHY

Video editing

I chose to show the manufacturing process. I wanted to show the view of some software. So I used the OBS software which is very quick to learn.

OBS is an open source software for video recording of the laptop screen

The metamorphosis must take place at the beginning of the video so as not to spoil the surprise effect. I chose an epic music on the bensound website:: evolution by Benjamin Tissot. It's really the perfect music as there are several music effects during which the deployment of the origami set at these moments is really the most impactful and moreover these effects are at the beginning of the music.
