Assignment Overview:¶
Group Assignment:¶
-
Review the safety data sheets for each of your molding and casting materials, then make and compare test casts with each of them.
-
Compare printing vs machining molds.
Individual Assignment:¶
-
design a mold around the process you’ll be using.
-
Produce it with a smooth surface finish.
-
And use it to cast parts.
Extra credit: use more than two molds parts.

3D Modeling with Fusion 360¶
I have used Fusion 360 to design my model. I decided to create a model that looks like a Heart that often symbolizes Love to some people.
It is not connected with my project but it is just a random choice.
The material I want to use is Silicon which will be molded by an eproxy mold composed in two parts.
To do this I have to make other two molds with the Wax to make the eproxy mold.
Designing the Part¶
Below I used combine and split body tool to create another part.
Below is a draft analysis of the box
And here we have the the other part created.
Wax CNC Machining with CAM¶
After finishing the modeling exercise let us switch from designing to Manufacturing to set parameters and select tools to enable us generate G-code for our CNC Machine for the milling process.
Setting Parameters
Below is a short video of the process in CAM simulation.
