There are other methods of small scale manufacture though, it's not like 3D printing is the only alternative.

> It is thicker than an Xbox 360 controller at the base where the sides of the controller rest in your palms. The weight is about the same. I didn’t feel as if the controller was too heavy or too light. I did notice the bulk of the controller, but only as a differentiation from the PS3 controller I’ve been playing with recently (GTA5) and the 360 controller I use for PC gaming.

I'm not familiar with the Xbox 360 or PS3 controllers, but from this I think it was the size, not weight, "bulk" referred to. It's the same weight as the Xbox 360.
