I think people are just getting a little tired of the 3D printing hype. Yes, it's a cool emerging technology, but the sensationalism of these headlines and articles are a little grating at this point.
Calling it a "3D printed car" is not exactly lying, but it borders on disengenuous, seeing that the guts of the car are, of course, still manufactured the traditional way. It's apparently the body and frame that were printed, from what I can tell. Seriously, would that have been so damn hard to mention in the summary or the article? Oh, but that sounds a lot less impressive, doesn't it...
It was stated in the article that the car had 40 parts. I'm pretty sure they meant there were 40 printed parts, because there's no way in fuck you can build a car in 40 parts, unless you're conveniently counting the engine and frame as a single "part". Or maybe they're just counting each pre-packaged assembly as a "part".
I don't think people would complain quite as much if there was any real semblance of critical reporting here - less hype and more tech.
