Molding my first object
I never try molding and casting before and was really excited to try it out, the possibilities behind this process are really interesting and can be used in various field.
First thing I did was to inform myself about what kind of sillicone and casting material I needed for my small project. Luckily for me, I have two awsome users of the lab that are really used to work with molding and casting process. So I call them and scheduled a time with them so they could give me some information about what to buy.
Since it was my first time, I wanted something that I could work with a while before it gets rigid, so I look at all the sillicone available into the smooth-on chart and find that the moldstar 30 seems pretty good for me. Indeed, the moldstar 30 have a pot life of around 45 min wich is plenty of time to work with and dry in about 6 hours.
I decided to do it with holes and it worked quite good AND I exported the 3D mold model to a .stl file for the milling process.
2_MILLING PROCESS
For the milling process I used the Roland MDX-50 machine and the Modela Player software (Tutorial).Step by step:
1) Open .stl model and select milling machine.
2) Select material you will use. In my case WAX .
We need to create 2 process: Roughing and Finishing process for final and better details. The steps are the same but you need to change the milling bit diameter: 1/16 4FL LONG for the roughing process and 1/8 2FL BALL for the finishing.
3) Create a New Process [Roughing or Finishing]
4) Choose type of proces
5) Choose the toolpath to create
6) Define the cutting area
7) Set the origin and the cutting parameters
8)Go Milling!

1_DESIGN A MOLD
I wanted a chocolate minion mold, I've designed a one-sided mold.
3_THE MOLD
For the mold I use the Smooth-on® Mold Max 60 Silicone Rubber for food related applications. Again, it's important to read the product datasheet.
Step by step
1) Prepares the workspace with all the tools you need:
a plastic cup for mixing,a wooden stick to mix,gloves,weighing machine ( for measure the mixing) , and mold material.
Some tips before starting the mixture:
- Use transparent cups for mixing and see how is it going.
- 1 cm (min) silicon on top of material when you put inside the wax mold.
- Security! Take care of you!
- Mix with energy!
- Fill a cup with water,to get an idea of how much liquid we need for creating the mold.
2) Mixing Ratio: in my case, 100 part A to 10 part B. Mixture, 5 min at least!
3) Pour the mixture into the mold wax
4)Wait 24h (in my case) before extract the silicon mold
5)
4_THE CHOCOLOTE
Smooth- Sil® 940 - USER INSTRUCTIONS After the rubber mold has cured for 24 hours , it is introduced into an oven for 4 hours at a temperature of 100 °. Allow to cool and wash the mold cavity thoroughly with soap and water, rinse well and allow to dry before use.
