That doesn't mean it's not possible, as
really high end 3d printers can use metal (including Titanium). However, the cost of the printers and raw material needed to 3d print a multi-use firearm? It's probably easier to buy a functioning firearm (even if you can't legally own one).
So, this is by no means meant to be comprehensive, but I happen to know a couple of guys who are a) Total firearms enthusiasts, with a collection that includes some fascinating WWII stuff that is hella fun to squeeze off in the desert, b) Very practiced at 3d printing, c) Include one amateur gunsmith, and d) Professional career types who can afford the materials. So, totally anecdotal, but I know two guys who could do this on a lazy Saturday afternoon and I'm Joe Blow Nobody from Scantily-armed Soviet Massholistan. It's just a good thing neither of them are very active, politically.
It's not about the skills. In theory, I could get pictures of all the parts of a disassembled firearm, 2d to 3d convert them, and design the 3d files for a full working firearm in TInkercad.
It's the cost of home manufacture of a working multi use firearm using a 3d printer that's prohibitive.
A Prusa I3 MKS3+ (with enclosure), costs $1500 USD, and can print with Stainless Steel.
The next cheapest one is 4500, followed by $9100 and $12000 USD for a unit. These are using FDM technology, so the material is laid out in what is basically melted together strings roughly .2mm in diameter. What what little reading I've done online, even steel printed firearms that have been tested printing using FDM technology fail because of that. The prints lack structural strength to handle the explosion within the firing chamber that causes rapid-gas heating and expansion to launch the bullet. Simply put: FDM printed models explode.
I have no idea if Resin printing would produce a workable firearm, but I seriously doubt it. I've seen resin printed stuff get snapped by angry 6 year olds.
So, we need a different method. One that produces structurally strong parts.
The other method I know of for metal based 3d Printing is called 'Laser Powder Bed Fusion'. After looking at how much the cheapest 3d printer that uses that costs, and the power requirements, I didn't look any further into it. (I was looking out of curosity, as the 2 printing types I'm familiar with are FDM and Resin.).
The cheapest laser-powder bed fusion printer I could find a listing for? $99,000 USD.
The cheapest one that I know of that can do Titanium, Cobalt, or Chrome is $180,000 USD.
This is all without taxes, and people going 'and what do you need this for?' I don't think any of them are made by a US based manufacturer.
So, assuming that FDM prints will always fuck up, you'd looking at $99,000 USD for a printer that does Laser-powder Bed Fusion, and all sorts of questions from US Customs and the like.
And that's without the cost of material. There is a lot of waste material (supports), as well as 'trial and error' in 3d Printing.
Now, a roll of stainless steel (1 kg), costs about $88USD. Titanium costs 363 for a kilogram.
You might be able to get a single firearm out a roll of raw material, depending on a number of factors which I have no interest in exploring. I'm assuming it would get more efficient as you learned, but failures still occur.
So, RawShark, let me ask you this - are your friends willing to put out over $100,000 USD for a single 3d printer, put out the needed work to have it properly powered and vented (as in air tight room to keep the fumes from the printing out of the house, and then put through a filter system before venting it outside), and then probably have to spend a few hundred (or even a few thousand) more on raw materials, to get their first 3d printed firearm, that they could have picked one up at a Gun-show or a retailer?
I've been asked why I still follow a few of the people I know on Facebook with 'interesting political habits and view points'.
It's so when they comment on or approve of something, I know what pages to block/what not to vote for.
