We don't use one yet so I may be getting ahead of myself, but it'll help get a proof of concept made in days instead of months. The iterative process of drawing something up in CAD, sending to a manufacturer, and testing the prototype is painfully expensive and time consuming. I'm not suggesting we'd use it for production, just early prototyping.
