6. Computational Couture

References & Inspiration

Inspo

  1. While researching about computational couture I've found the work of Iris Van Herpen ans I was mezmerized. In the picture you can see two grments from her colleciton Micro (left) and Skeleton Dress (right).
  2. One of my inspiration for this week is tactile museum replica used for visual impared visitors to be able to feel the art pieces. On the left you can see a piece from the Tactile Tour in Brussel and on the right a piece of the tactile station at Louvre Abu Dhabi made by Tactile studio
  3. Studio Oxman, "biologically programmed, computationally grown, and robotically manufactured shoes and textiles that give biodegradable bioplastics the design that their biology deserves"

Tools

Grasshopper tutorial

it was very intense

Below I made a table with the main command of grasshopper that have been helpful for making my model (aside the amazing support of Aslı)

Basics

Grasshopper basics (credit: Alessia Talò)

Grasshopper is a visual coding tool tightly integrated with Rhino’s 3D modeling tools. It works with data and algorithm as essential of any parametric design solution.

Project

Grasshopper

I tried out different things before sticking with one model

tests

In the top and bottom left I was trying to work with the Differential Growth. When using simple shapes it worked fine, but once I tried to use a vector file of one of my painting things got complicated.

tests2 Other image sampler tutorial that I tried are Easy Grasshopper Tutorial and How to use Image Sampler Rhino Grasshopper Tutorial

  1. I followed the stemps showed in this Image Based Mapping tutorial to convert a low resolution image (100x137 px) into a grid and then define surfaces.

Final Grasshopper file[^2]

Tools used

  1. I tweaked a few things: moved from y axes to the z axes

  2. Now I got stuck and Aslı helped me and figure out a way to turn the output into a printable 3d model on fabric:

  3. Multiply the values of the picture so it would get higher and so printable
  4. Made a subtraction between the slider and the AxB coomand.
  5. Cleaned the tree
  6. Moved the top points down to be able to make a loft in between. You cannot make a loft if the starting points and last points are at the same level
  7. We used the Cull Pattern (manage boolean > define trues and falses) to work with every other line to have a flexible model.
  8. We extruded the z lines (1 mill) in the y direction (the extrusion must have a close breep)
  9. After many trials on Grasshopper, we had to clean the project on Rhino through the Boolean Difference

PrusaSlicer

PrusaSlicer is an open-source software that helps you prepare your file for 3D printing. In the image below you can see the setting we use for printing.

3D Printing

Preparing the printing surface

  • Clean the surface with alcohol. Remove residues of filament and fingerprints

  • You can remove the print board, just be careful with the screws when putting it back.

Filaments

Credit: Aslı Aydın Aksan
  • Keep filaments in their sealed boxes.
  • Use the holes on the spool so the filament doesn’t stay loose (it can get tangled).
  • Place the filament on the roller.
  • Cut the end of the filament at an angle.
  • Insert the filament → Load Filament → choose Flex (for TPU) or PLA filament

Loading file

  • Insert the SD card or USB stick and choose the file.

  • The printer will calibrate automatically.

Steps

Printed object

I used a colour change by temperture film, when cold it appears red, once heated it becomes yellow. Colour Change filament

This is how my final print looks like
