7. Computational Couture#

introduction#

When I googling around for contents about Rhino and Grasshopper, I came accross a webinar, “Visualizing Mathematics in Rhinoceros” by Professor Henry Segerman.

You can find a lot of other designs on the web. The webinar forcues on visualization of mathematics, but I can saw it as textile pattern design. I think that a mathematical 3D-printed object on textile will be an elegant design itself, but if there is a light, but a shadow of an object will produce a design on a blank surface of a textile. I wanted to make something like this somehow. Here is what I made.

grasshopper#

I wanted to design a sphere with holes on its surface. I referred to this tutorial (in Japanese) and changed a bit. Components I used are as follows.

Params>Input>Number Slider
Params>Geometry>Surface
Maths>Domain>Divide Domain2
Transform>Morph>Surface Box
Params>Geometry>Geometry
Surface>Primitive>Bounding Box
Transform>Morph>Box Morph

Here is a grasshopper definition.

3D printing#

Printing conditions are as follows.

3D printer: Replicator2X (Makerbot)
filament: PLA
nozzle temperature: 200
bed temperature: room temperature
printing speed: 4800 mm/min

Now printing…

Printed successfully.

I put it on a fabric.

When I shined my iPhone light on the object, shades were projected onto fabric. I thought the object was a bit small, and the shades didn’t extend much.
