Week 15 - Wildcard week¶
Assignments | Week 15 | Wildcard Week
Individual assignment
- Design and produce something with a digital fabrication process (incorporating computer-aided design and manufacturing) not covered in another assignment, documenting the requirements that your assignment meets, and including everything necessary to reproduce it. Possibilities include but are not limited to wildcard week examples.
Learning outcomes
- Demonstrate workflows used in the chosen process
- Select and apply suitable materials and processes to do your assignment.
Introduction
This week is different from other week, because we are free to choose the fabrication process that we are going to use.
In this documentation you will see a
WaterJet Cutter¶
Stéphane animated a one to one waterJet workshop to show me the workflow of using it.
The waterjet cutter works with a high pressure hydrau and a contener with sand. it works with water compression. When the water is compressed as a jet, the tube of sand become a vaccum that send the sand in a very quick speed.
After I saw the different objects that has been cut by the water jet cutter, my first thought was “”
Machine: Protomax Waterjet¶
What I’ve learned
I learned the essentials for using a waterjet cutter.
The size of the object must be superior than 1~2mm because the kerf of the cutter is almost 1mm
About Machine maintenance
**Before cutting**
Plug the mixing tube on the and let the water take the sand
**After cutting**
Unplug the tube and let water flow
Idea brainstorming
After the workshop, I opened the video of the class, and watched a few minutes. Neil said that we have to document what we did but also the assignment itself. It means that “you have to document the problem you are solving”.
By “document the problem you are solving”, I understand: Explain the purpose of your project.
I started to find the materials that I’m going to use, and at the same time, the shape of the object that I’m going to make.
| Object | Width | Height |
|---|---|---|
| Glass plate | 305 mm | 406 mm |
I had multiple ideas of project for the WATERJET Cutter. The First idea was a trophy in glass. It was finally abandoned because after the summer holidays, we couldn’t find the glass to cut. A hard lesson: don’t procrastinate when you have an idea to realize and, especially when you have prepared for a long time. The second idea lived for several minutes in my head. It was a mirror : a reflexive aluminum + glass. Yes, I dropped quickly the idea to make a thing that requires glass, but I still find this idea attractive. I’m curious to find out how to make a handcrafted mirror and the history of the mirror.
I use inkscape to design the measure of the ruler.
In order to have a relatively correct measure, I started by drawing 3 straight lines:
In (mm)
| X: | Y: | W: | H: |
|---|---|---|---|
| 30.0 | 10.0 | 8.0mm | 0.5mm |
| 30.0 | 11.0 | 4.0mm | 0.5mm |
| 30.0 | 15.0 | 5.5mm | 0.5mm |
The 8 mm line represent each 1 cm
The 5.5 mm line represent each 0.5cm
The 4 mm line represent each 1 mm
