I understand the intent, but feel that there are so many other loopholes that put much worse weapons on the street than a printer. Besides, my prints can barely sustain normal use, much less a bullet being fired from them. I would think that this is more of a risk to the person holding the gun than who it’s pointing at.
I mean, kind of, yes. CNCs have been one of the big items for export controls. Especially if they can be used to build weapons, parts for nuclear subs, etc.

In the US you don’t need a license to purchase a CNC. Even items with export restrictions like night vision goggles (Under ITAR) can be bought by anyone and shipped to your door. The export controls would only come into effect upon you exporting them.
Besides not needing a license for export controlled items within the country, you don’t need a 6 micron precision lathe
Until you want to replicate your dick
Just export controls though?
Given that human chromosomes are on the order of 5 to 10 microns, I am thinking this export regulation doesn’t apply to the hobby market. This is “use the machine in a clean room” level precision.
@FearTheCron @YourAvgDuckHead According to encyclopedia Britannica, I’d say a fairly reliable source, your out by a factor of 100. https://www.britannica.com/science/chromosome
A human blood cell is approx 10 micron long, according to this… https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2998922/
Apologies for the pedantry, I couldn’t help it.
Hehe, I just grabbed the number off wolfram alpha’s size comparison. Wouldn’t surprise me if they are wrong, not sure where they scrape the data from. Anyway, my point stands, six microns is still stupidly small. Some dust or hair on the cutting edge and your precision is now out the window.
Oh wow, TIL! I guess I’m not surprised, consumer GPS is kneecapped at a lower accuracy for similar reasons
It used to be. It was called selective availability, where the DoD could dial up/down the accuracy for commercial receivers. However, it was discontinued in 2000.
