 # 13. Casting and Molding 
 
+This week we moved away from electronics and focused on molding and casting. This is something 
+I have never done and should be an exciting week 
+
+For the group assignment we cast a number of different materials and it was very clear that 
+choosing the right material is key as well as following the prep process in detail.  You can 
+see our results [here](https://fabacademy.org/2023/labs/charlotte/assignments/week13/)
+
+
+**Goals** 
+
+1. Design a mold around the stock and tooling that you'll be using, mill it (rough cut + three-axis finish cut),
+and use it to cast parts
+
+

+
+2. Made a soft mold and cast hard parts
