assignment

   design a 3D mold, machine it, and cast parts from it

 

I decided to do a big button for my interactive survey that will be used in my final proyect.  First, I did my 3d mold in Fusion 360.  Below is a video of how I did it.

The steps that I followed were:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

1. Design a surface of 2.5 cm of depth.

2. Add a layer of 5mm of depth and substract it from the original surface

3. Add a circle with 20mm of depth

4. Add text that was over the circle with an extrusion of 15mm

 

In this way, my figure will be a botton with some letters that will be as a hole.  I also tried to design it in Rhino as well.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  While I was designing it in Rhino my adviser, Aristarco, suggested to make it in the laser cutter with using different layers and I thought it was a great idea. And this is what I did.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

In order to machine it I used the lasser cutter, then I realize that I needed to machine it with a router or a Modela... continue to see the real assignment.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I started pasting my pieces with white glue in order to add the layers, and after that I prepare my surface with wax before I added the synthetic resin.

I used a polymer resin in order to make my button.

I added a catalyzer in order to make it faster.  Before I added the polymer I added some wax so the material would get stock into the mold.

 

Then I realize that I need to machine something, which meant that I needed to use the router or the Modela.  Then I realize that I needed more wax in my previous mold because the figure cannot come out of it.
