I think you would be surprised at how many wannabe gun owners know somebody who can read a printer manual.
Just did a bit more reading on the Liberator and it's development. You might want to read up a bit.
The gun was created with a low end material, ABS plastic on a low end industrial printer (that only cost $20,000, where have you been pricing assault rifles?). As of right now, the low end printers can't handle higher quality materials (require too hot a temprature) which is why the firearm is prone to explosion and rapid breakdown. Getting past that hurtle would either using better machines ($100,000 - $400,000 range) or someone developing a technique to use the higher end Plastics in the lower end machines.
Interviewee does make it clear that a home enthusiast could take a desktop system such as Makerbot sells and modify it to work in the higher temp ranges, and change the code to be more precise. Such development would require far more then "being able to read a printer manual". There will obviously be home printers that cater to those interested in plastic firearms, but most of that crowd can already buy guns legally and without being tracked.
I guess my question at this point is what is your area of concern here? My first interpretation is that you were concerned that someone who wanted a gun fast for illicit purposes (aka ex-hubby wants to shoot his ex-wife) could use this method, which seems pretty unrealistic at this point and for at least the next few years.
If your concerned that gun buyers will suddenly have a new method of buying guns that can't be tracked, you have a point but it's hardly the biggest issue with gun control right now. They already have methods to do that that haven't been closed, are far more time effective and give them access to usable guns.
