back to article 'First' 3D-printed rifle's barrel splits after single shot

3D-printed weapons are back in the news, after a rifle billed as the first such device designed to be created on 3D printers was put through its paces with mixed results. Someone called “Matthew” who writes an instrument making journal and runs a YouTube Channel in which he shows off 3D-printed ukuleles yesterday added a video …

Re: One up the spout!

Pendantic grammar nazi fail:

"igniting a bullet's" is a shortening of "igniting a bullet is".

Err .. so "Adam's mistake" actually mean that Adam is a mistake ..?

Re: One up the spout!

Igniting a bullet is impossible. Firing a round is possible but very dangerous no matter where you position yourself relative to the barrel.

Isn't getting a metal pipe from the hardware shop more effective than printing a plastics (and plastic) barrel?

Which is more dangerous a disintegrating plastics or metal barrel?

Re: One up the spout!

No, that would be "Adam's a mistake". The particle "a" is required.

"Adam's mistake" is short for "The mistake of Adam." This is a possessive apostrophe.

"Adam's a mistake" is short for "Adam is a mistake." This is a contraction apostrophe.

"Igniting a bullet's not the hard part.." is a contraction. The 's is a contraction of "is".

"Igniting a bullet's charge", which is not in the article, would be a possessive apostrophe.

I'm assuming you're a non-native speaker?

"I'm assuming you're a non-native speaker?"

Even many native speakers of English do not understand the correct use of the apostrophe. I was actually taught that contractions should always be avoided in written English (except within quote marks) to avoid confusion.

"Contractions should always be avoided in written English."

With respect, you were taught by an eejit, then. The idea of a strict separation between the spoken and written versions of a language is not popular in English, where our writers have a long history of trying to capture the way people actually speak (Dickens, Puzo, O'Brian, Pratchett, Austen). We're not like the French, with their bloody past historic.

Living in the US, that sentence could have ended with any number of other items the nativists don't understand.

Did you RTFA?

"igniting a bullet's not the hard part" is a shortening of "igniting the bullet is not the hard part" (ignoring the obvious problem that igniting a bullet is actually an extremely difficult undertaking).

Punctuation nazi!

Actually punctuation is not grammar.

Grammar is the set of structural rules that governs the composition of clauses, phrases and words in any given natural language.

Punctuation marks are symbols that indicate the structure and organization of written language (as well as intonation and pauses to be observed when reading aloud.)

So there.

Re: One up the spout!

You were taught incorrectly. Contraction is perfectly acceptable in written English. Formality of writing is a sliding scale, but this article was written in a jovial, informal style. The contraction was perfectly placed.

Two things are going on, thermal and physical shock. Both of which would be difficult to engineer with plastics.

Neither are particularly difficult to engineer with "modern" plastics. However engineering for such with the types of plastics that 3d printers use, now that's entirely different problem...

I'm sure a couple of layers of duck tape tightly wrapped around the barrel and the receiver would have kept the gun intact (at least for more than 1 shot)...

Waste of time

"In related news, Danish 3D printer maker Create It Real has decided to ensure its products can't ever print a gun."

A gun is made of lots of different pieces. Just print the pieces separately and you'll bypass any stupid restriction they might set.

Re: Waste of time

Oh, very likely they did think of that. What they probably didn't think of, is the vast category of household, toy or hobbyist items that do share characteristics with some part of a gun - and therefore become unprintable.

You make the gun parts from aluminum and then print the rest.

So if you want, you could have someone buy a Ruger 10/22 receiver, after market barrel, and then print the rest using your 3D printer. (industrial model)

But still, it would even be cheaper to use another tech to create your skins and add ons...

Re: Waste of time

The design of a 10/22 will not prevent you from modifying it in such a manner. The receiver design is such that all the firing components are inside the single part receiver assembly. The only parts below the receiver is the trigger assembly which you can modify if you want, but it shouldn't be necessary for what you are proposing.

As long as you don't modify the receiver you can do anything you want to a 10/22 safely. Make all the 'skins' you want out of anything you want. It will not affect the integrity of the firearm.

That is what jumped out at me from TFA. How do they hope always to recognise gun parts? Or they will spread the net so wide that they will stop you making many common things, like any tube about 6" long and 1/4" bore, even if it is for an oil pump. A bit like you cannot type "Essex" on many forums.

That's the problem when you build the capability, courts are going to expect you to use it.

Re the thread more generally: Not for nothing but how do you even define a gun? It's just a tube, they gonna not print all tubes? The system obviously isn't AI so don't build something that implicitly looks like a gun. Software neutered successfully.
