Is CNC machining faster than 3D printing?

CNC machining usually is capable of removing material much faster than 3D printing can deposit it. Size usually does not play into the time constraint as much for machining; the amount of material removal required is much more critical.

Is 3D printing cheaper than machining?

Cost. Though on average 3D printing is cheaper, costs depend on how many parts are required and how quickly you need them. For larger quantities (higher double digits to 100s) CNC is likely to be more appropriate. For low volumes, 3D printing is more appropriate and lower-cost.

Why is 3D printing so slow?

3D printing requires time due to how complex it is, how it is conducted layer by layer. There is no technology to create objects in the blink of an eye. The speed of printing is dependent on the quality of the print-out. But this shouldn't be considered a disadvantage in light of the enormous potential of a 3D printer.
