WEEK 8. Computational couture

Creating Shoes with Parametric Design

The first image on top is of the recent Yeezy's which resemble Croc's.After seeing this I was encouraged to make a digital shoe, I even thought of copying this. I then thought back to the shoes in the second image from reshape and was found this was even more beautiful. So I set out to make a shoe which pulled ideas from both sides.

The Photos about Cage Edit come from the tutorial. This was my fist trial of getting used to drawing around a foot.

VORNOI FOOT

In mathematics, a Voronoi diagram is a partition of a plane into regions close to each of a given set of objects.

The foot mesh I downloaded had over 20000 faces and it was impossible to use it Grasshopper. So my friend came up with the Brilliant idea of OSnapping by Vertex and drew a bunch of curves to make the foot for ( in this case half). In Grasshopper one has to import the curves, merge them then loft and finally put them into the surface. Once Surface was created I was able to use this tutorial which concluded with a surface morph.

For the 3D printing phase I used the Filaflex of fillament (2.85 mm thickness) with the extruder heated at 235 degrees celcius. In settings is important use Retraction Distance at 3.5 and Retraction Speed at 40 using a Flow of 110.

Making a better Mesh

At this point I reached out to a good friend of mine, as the definition above needed improovement. In the images below, you will see the code started with it's origianl lofting to surface. The major changes which made this case more interesting were the uses of Vornoi 3D, Weaverbird Thicken and Catmull-Clark Subdivision. As you scroll down more you will see the images of the process, the 3D print setup and final model.

I would like to take this project further, this how: -By getting accurate foot scans -Improving the lines I draw around the foot so I can unroll the Mesh. -Finally taking the unrolled surface and applying the Grasshopper patterns. -Overall objective with a foot pattern one could print the pattern onto Fabric and latter assemble. Also the Grasshopper journey shall continue.

"3D printing screen for the shoe. Apart from the four and half hours of printing, this model hard to print. Reason being is that the part goes in quite and a 3d printer is challenged when printing at angles. For this reason we have supports all around the shoe (blue parts)."

3D Printing: Cura software interface to start 3D printing

Here are the necessary steps and instructuions for getting from a 3D model to a printable Gcode file. In my case we used a FilaFLEX fillament (2.85mm thickness). Using Retraction Distance at 3.5 and Retraction Speed of 40 with a Flow of 110. Also I used support because of the geometry of the model.

  1. Always export meshes

  2. Never export open objects

  3. Cura Software

  4. Infill density 50% is good

First Class notes

In the first class with Eugenio(Noumena), we jumped into some components which create intricate patterns. The components I found interesting were Vornoi, Boundary Surface and Region Intersection. I would eventually go on to use the Vornoi as the core of the shoe I modelled.

By the end of the first class we had completed a Pattern including the Vornoi component model ()

3D Printing - additive manufacturing

During our class I took the liberty of searching for most of the technologies that were mentioned. A few few examples as you will see below are the Resin 3D printer, the difference Stereolithography and FDM ( illustrated in images). Also I included a few diagrams forecasting the future of 3D printing.

Grasshopper Class 2

First idea we looked into was making a Vector field component. This revolves around using points for attraction and points for retraction. After this we went on to make a pattern using various rectangles.

Class 3 Grasshopper theory

In this class, Eugenio explained the principles of Lists and Data. Moreover he showed the different functions of the "Flatten" "Rhino no data organization just geometry. Grassshopper includes Data organization."

Eugenio's Simulation

Eugenio walked us through a Grasshopper definition which involves a Simulation which joins the sewing line. It also uses the Kangaroo Physics components such as Smooth."Grasshopper always tries to make you put more information" decay close to zero is a force never losing power lower decay value means more interaction ( nice patterns)
