 ## Moulding and Casting
 
-* Design a 3D mould, machine it, and cast parts from it.
+Group assignment:
+* Review the safety data sheets for each of your molding and casting materials
+* Make and compare test casts with each of them
+Individual assignment:
+* Design a 3D mould around the stock and tooling that you'll be using, [mill](https://en.wikipedia.org/wiki/Machining) it (rough cut + (at least) three-axis finish cut), and use it to cast parts.

 ## FAQ
 
 ### Should I read the MSDS and TDS this week?
-> Answer:
-1. It is always a good idea to read these documents.
+> Answer: Yes, always.
 
 ### I want to only make a wax mould, and cast something in it - is that acceptable?
-> Answer:
-1. Learn and go through the 3 step process first . To break the rules you have to master the rules.
+> Answer:Only after you learn and go through the 3 step process. To break the rules, you have to master the rules.
+
+### Can I 3D print the mold? Can I do a lasercut?
+> Answer: No, for this assignment you must mill the mould using a CNC milling machine. After fulfilling the requirements, please go ahead and experiment other techniques for fabricating moulds.
