Hmmm. Don’t suppose there would be workarounds for that. Nah.

and a NEW printer head costs???

like having crime shoes that are only worn when omitting crime so there's only one pair to hide/dispose of, printer heads are even easier to hide

same thing with pistol barrels, slide and firing pins, it's not rocket science

Sample size of 14.

With regular inkjet printers, you can easily change the printhead. Wouldn’t you be able to do that with additive 3D printers? Seems like it would be easy to send the evidence to the landfill.

“Sample size of 14.”

Don’t worry, new legislation will require all 3D printers to be “fingerprinted” before leaving the factory. The database will soon have 100 million 3D printers in it for forensic purposes only.

The implication here is that homemade 3D-printed guns are inherently illegal and/or would naturally be used in a crime and would be something that the police would (of course) want to track.

Why make these assumptions? There is nothing wrong with making a gun.

Control freaks are worried about control. Again.

A couple years ago I read that regular printers have something embedded in the ink or ink processing that can identify the origin of printed documents. It was a long time ago, and I think it was Rush who mentioned it.

All before any actual crime has been committed with a 3d gun. The un-governed mind.

My dad and I built black powder kits when I was a kid. They were a blast! We built every one they made from the duckbill pistol to a Sharps 50 caliber.

It’s strange—we never killed anyone with any of our homemade, unregistered weapons.

Biography of the scientist:

Currently, Dr. Xu is an Associate Professor of Computer Science and Engineering Department in the State University of New York (SUNY) at Buffalo, where he founds and directs the ESC (Embedded Sensing and Computing) Group.

He has published over 140 technical papers, co-authored 2 books and is a named inventor on several international and U.S. patents.

He received the Ph.D. degree from University of California, Los Angeles (UCLA) in 2013. He got both M.S. degree in 2008 and B.S. degree in 2006 from Zhejiang University (both with honor), China.

hmm, what country has the most to fear it's population obtaining "unregistered guns? Fellow must have had PRC approval to travel abroad being such valuable asset to PRC.

just sayin'

It is actually edncoded several on each page but you wont find it with the naked eye. It is on the page several times but the components of each incidence are distributed. You will need a strong magnifying lens and you will need to compare like letters. What you are looking for is missing dots. A person who knows what they are looking for can find it in no time. You will have a problem. It has nothing to do with the print head. It is hard coded and is done so that it cannot be flashed. Changing out device memory or processor wont help either. The code is resident where you won’t find it. Laserjets use a very similiar process.
Don’t use your inkjet or laser printer for nefarious purposes. If the power that be want you bad enough the can trace you through it. You could try second or third hand equipment but that be traced as well. Dont forget about fingerprints or DNA - you’re shedding it all the time.

Right. Now I remember what Rush said — that it’s in the dots. Ever since then, years ago, I have always been careful about what I print and send.

And I’m am “ID Adict” so know all about DNA being left behind — skin cells, oil from skin, etc.

If someone considered living a life of crime in this day and age, it would be rough.

We use fine sandpaper for a final finish on the parts.

I believe you are referring to Steganography, the practice of concealing messages or information within other nonsecret text or data.

The 3D Printer ended up sinking to the bottom of the lake in a boating accident.

But its printed guns still work.
