In the passage from America the Ingenious, how does the author advance his point of view about 3-D
printing?

here's what i know

Industrial 3-D printing is at a tipping point, about to go mainstream in a big way. Most executives and many engineers don’t realize it, but this technology has moved well beyond prototyping, rapid tooling, trinkets, and toys. “Additive manufacturing” is creating durable and safe products for sale to real customers in moderate to large quantities.

The beginnings of the revolution show up in a 2014 PwC survey of more than 100 manufacturing companies. At the time of the survey, 11% had already switched to volume production of 3-D-printed parts or products. According to Gartner analysts, a technology is “mainstream” when it reaches an adoption level of 20%.
