 ====== Week 6: Computational couture ======
-This week's assignment was to create a parametrical pattern using **Grasshopper**, the plugin for Rhino, and 3D print it. I created 2 designs - one 3D printed on fabric and one stand alone design. Both were printed using flexible filament.

 ===== First design =====

 For the first design, in Grasshopper I created a square grid using number sliders for the X and Y so that the grid can be adjusted to any size. I then used the points in the centre of each square as the starting point for a circle. I made the radius of the circles controllable using a number slider. I then used the pipe function to make the circles more solid.

-After this, I used the  settings below in **Cura** (the program for slicing designs ready to be 3D printed) to print the design on fabric. I had to clip the fabric to the bedplate in order to keep the fabric stationary. I used a slower speed because the flexible filament needs more time to be extruded.

 ==== Second design ====
-For the second design, I wanted to create a stand alone weave structure. Having no experience in Grasshopper, I needed to use a tutorial (http://www.grasshopper3d.com/video/defining-a-parametric-weave) to create a weave and I adapted it slightly to experiment with a new design. The change I made to the original design was to mirror the design on top of itself - to create 2 layers of the weave structure. Printing this double structure with flexible filament, I was interested to see the results, how it would feel and what it would be like when pressed together.

Having no experience in Grasshopper, I needed to use a tutorial ([[http://www.grasshopper3d.com/video/defining-a-parametric-weave|http://www.grasshopper3d.com/video/defining-a-parametric-weave]]) to create a weave. The main steps of the tutorial are as follows:
-I used the same settings in Cura as the previous print on fabric, however I encountered problems with the print. The first layers of the material were not sticking to the bed. I increased the temperature of the bed and also put down some sticky tape to help the layers stick better. The print improved, however, I still had problems. A colleague helped me with this problem by re-calibrating the height of the bedplate so that the nozzle would be closer to the bedplate. This solved the problem and the weave structure was printed successfully.
+Select Square Grid (Vector tab), add number slider to the x and y directions - so that the size of the square grid (therefore the weave) can be adjusted

+Create a Cull Pattern (Sets tab, Sequence), with boolean toggle values (Params tab, Special) as input i.e. true or false, and link to a tree Branch (Sets tab, Tree) - in order to isolate different points to then manipulate separately (to create the up and down directions for a weave)
+Move a row of points up

-It was useful to experience Grasshopper, however I found the program difficult use. It was hard to me to find the right function that I needed for a design element I had in mind, and to know what input the components required; often, the  program produced results I didn't expect. I am aware that my first design is very simple, as I found it difficult to produce a more complicated structure that I wanted.

-I am happy with the final products however. The flexible material makes them pleasing to touch and handle. The weave structure is flexible but also firm when pressed; this could perhaps be a useful structure to absorb the impact from movement.
