Research & Ideation

First, search "What is a parametric pattern?" After watching the recording lecture, review especially about parametric fashion. While I was traveling, looked for parametric examples in familiar.

New tools like Rhino and Grasshopper appeared, causing a lot of confusion! Started by watching YouTube tutorials and tried creating programming on Grasshopper in the same way.

@From Pinterest research

One of my themes is tea leaves, so I thought it would be interesting if the leaf shapes or veins could be made parametrically. However, since I still didn't fully understand Rhino or Grasshopper, I wondered if I could start by creating a simple design, so I decided to try making a parametric triangle.

Maker Faire Ogaki took place in November, and there was a piece from Seian University of Art and Design (Shiga Prefecture, Japan) that perfectly represented Fabricademy. It featured 3D printing on thin fabric like organza, and when viewed from the back, the printing sandwiched the organza.

Process and workflow

Step 1.

I tried creating a parametric pattern with triangles. First, start by adding Grasshopper as an attachment in Rhino."From Rhino's top toolbar, go to 'Tool,' find 'Grasshopper,' and click on it.

Alternatively, type "Grass..." in the Command section at the top, and a tab will appear. From there, select Grasshopper.

Step 2.

While watching the tutorial, I add each component one by one in the same way and connect the components to each other.

Step 3．

However, the lines appearing on my screen are white, displayed in a different color from the ones in the reference material.

Step 4．-TRY AGAIN!

However, the line color doesn not matter. I can change it also the description into full name in order to what each means exactly.

HOW TO DO

In Grasshopper, select the component you want to display with its full name.

Click the Display tab at the top, and then simply click Draw Full Names!

Step 5 -TRY ANOTHER PATTERN!

HOW TO DO

A- Create vertical and horizontal points.

B- Draw different circles at each point.

C- Change the diameter of each circle based on its distance from a given curve.

D- Extend upward from each circle to create a cone. Adjust the height of the cone based on its distance from the same curve.

To determine the distance from the curve:

1. Use Curve Closest Point,

2. Specify the points to measure,

3. Define the reference curve.

4. Measure the distance from each point to the curve.

E- The Extrude Point is extruded upward from the specified point.

Specify the point:

Keep the X and Y coordinates connected as they are. For the Y coordinate, create the height based on the distance and remap it accordingly.

HOW TO PROCESS BEFORE PRINTER

1.

Design triangular and tetrahedral geometric patterns using Grasshopper. Process the completed data with Bamboo Studio software.

2.

To print on organza, you don’t lay it down from the beginning. Instead, print a bit without the fabric, then pause the printer. At this point, lay down the organza and continue printing the rest.

3.

In Bamboo Lab, you can add a pause by right-clicking on the bar at the right edge of the screen (where the time is displayed).

4.

Slice the file again with this setting. Then, click "Export plate sliced file," use a card reader, and transfer it to the Bamboo Lab printer.

HOW TO SET IN PRINTER

1. Output a layer about 0.2mm thick with the 3D printer.

2. Pause the printing process. Lay the organza over the layer and secure it with masking tape to prevent movement.

3. Continue printing the rest. By printing in this way, with the organza sandwiched between layers, it seems possible to achieve both clean output and well-shaped structures.
