+
+## Advantages of Machining Processes
+
+- High precision of geometrical dimensions, tolerances, and surface finishes
+- Is able to make one off prototypes in production grade material
+- Creates high volume production tooling
+- Increasing hard/brittle/fragile/tough materials can only be machines
+- Some designs are so complex that machining is the only realistic process to make them with
+
+## Disadvantages of Machining Processes
+
+- Material is wasted (as it is a subtractive process)
+- Complex parts require expensive machines to make and making them can take a long time
+- Parts need to be set up using fixtures. These fixtures get increasingly complex with the part.
+- Faster production rates and harder materials wear down the tools.

 [^d_deflocculant]: a substance which, when added to scattered particles in suspension, causes a reduction in apparent viscosity. Deflocculants are substances which prevent flocculation by increasing zeta potential and therefore the repulsive forces between particles.
