actually the reason houses, cars, and airplanes are not cheaper than they were say 30 years ago is because of government regulations for the most part, and because the average consumer wants more packed into those items which also raises the cost. however, cars, airplanes, and houses are long lasting items, that can be constantly rebuilt as needed, and thus are still a relative bargain if people were willing to properly maintain them.
Technically, once you adjust for inflation, housing and transport is cheaper. Housing is 2X as large as it used to be and oil/gas isn't cheaper though, but we are talking about a printer. How much would a laser printer have been 30 years ago? Is there any reason a 3D printer won't follow the same course?
Interesting technology, but for firearms production, I have to wonder...why? The 3D printing machines that can print metal parts are rare and expensive. If you print firearms parts on one, it's pretty easy to source back to the relative handful of machines sold that are capable of building it. As opposed to say, a <$1000 mill-drill machine that can produce one and which can be bought at any Harbor Freight.

Well, it is a lot easier for the normal person to just download the file to print a gun or anything else, than it is for them to do actual handy man stuff.

I'm not so sure that "normal people" are as capable of operating one of these machines as you think. I'd also like to know how much secondary processing is required after the parts come off the machine. My experience with rapid prototype parts (primarily SLA) is that a good bit of knowledge and post processing is required. Though that may be dated, it's been a few years since I've dealt with the technology.

Yea, I have no experience with 3D printing myself. However, I'm sure that the ultimate goal is to have software and the hardware be as easy and simple as possible for the normal person. Where all a person needs to do is make sure the printer material is full, the printer turned on, and then open the software on their computer and click on an image of what they want to print today.
3D printing IS NOT as simple and point and click. It requires hundreds of thousands, and perhaps millions of dollars of equipment and materials. Libs... You can all settle down.
Ours cost 10 grand. We use it to prototype enclosures. Cheaper than paying someone else to tool up to make three of something so we can decide it's designed properly.
Not a firearms enthusiast myself, but... Aren't gun barrels supposed to live up to some pretty hardcore metallurgical specs, at least for longevity and reliability?

Yes, quality ones are usually proof tested, and are also held to a very tight tolerence. IIRC a normal barrel is held to ~+/- .0002-.0004" diameteral tolerance throughout it's length. Precision barrels are lapped, and IIRC are held to about +/-.0001 througout their length. Much variation is dangereous, tight spots will cause excessive pressures.
