Traceable 3D Files?

[NinjaTard]

Saw this article and frankly I'm confused how this would even work. Seems like fear mongering to scare people out of printing frames and other things but maybe I'm missing the point or just ignorant? What do you folks think?

3D File Digital Fingerprints

it wouldn't actually work, a good thunk or releveling the bed will change the "fingerprint" the only thing that could be useful for is for IDing things from a printing service but most don't do anything obviously 2a.

Mostly nothingburger. IMO. Could argue 1A, 4A, 5A, protections covers things like this. Though the whole CRS/Auto key card thing does make things a little more iffy with regards to drawing ""machine gun parts"" onto a metal key card

If that particular case is start of a trend, expect anti 2A ATF examiners to declare that merely having the STL files for anything NFA (machine gun parts, silencer parts, AOWs,destructive devices), and also anything frame & receiver related (GCA 1968) to be "constructive intent" not like they already tried with regards to "ghost guns" and "frame and receiver rules"

It might go as far as declare blueprints, schematics and having a Bridgeport mill and lathe and/or a CNC machining center, along with 3d printers to all be "constructive intent to violate GCA1968 and NFA 1934 laws"

It sounds like lines embedded into the actual files. When I worked in programming, we embedded certain lines in digital video files which were needed for use in the courts as the files came from security cameras. Its probably a 256 bit key (or whatever size) that's placed in the file. A hex editor (similar to a word processor) should show the added lines.

This is different then I thought it was, but if this was implemented it would be bypassed in seconds by the 3d2a community. Flashing new (or old) firmware onto a printer would fix it and it just wouldn't work on an open slicer.

Downloading an STL isn't unlawful to my knowledge. It still needs to be sliced and converted to gcode for your printer to interpret.

1. Don't connect your printer to the internet/wifi
2. Move gcode manually using a micoSD.

Or you could have convenience, convenience is nice.

Yes, discuss more……

I know nothing about this world. But could a person download a file, print out a sample part, then scan that part and create a new clean file with no trace embedded in it? then destroy the first sample.

Depends on the implementation level, printer "fingerprint" no (but it can be changed), printer firmware level no (but it can be changed), Slicer level no (but it can be changed), File level yes (but it's far easier to edit the file itself).

Looking at the article and further on-line research, it looks like how the "fingerprint" is embedded into the project is pretty hush-hush. I did find this information on color 2-D laser printers, that I was unaware of (apparently in effect since the 1980's in some form/fashion). So if you are planning on counterfeiting or writing ransom notes, you may want to review this first:

The thing with 3d printing is that it started and continues to be a very DIY and Open-Source hobby, that and the material properties are why it hasn't grown in popularity very fast.

Gentleman,

Please stop what you're doing and meet the agents sitting across the street from your front door.

They have some questions….

They might not know theyre building gun parts, or dont care but lots of gun parts get printed. I have many printed in metal.

Oh yeah, it definitely happens, there are whole 3d2a projects based on services that officially don't do gun parts that really just don't do machine gun parts, but even they wouldn't print a glock frame or ar reciever.
