3D-printed weapons might change into “the weapon of alternative” for criminals and violent extremists all over the world, an knowledgeable has instructed the BBC. These DIY, untraceable firearms have been recovered in a number of current prison circumstances, together with the alleged use of a partially 3D-printed gun within the killing of United Healthcare CEO Brian Thompson.
BBC Trending has investigated the worldwide unfold of 3D-printed weapons throughout social media platforms together with Telegram, Fb and Instagram, in addition to web sites providing how-to guides.
3D-printed weapons, typically described as a kind of “ghost” gun, are untraceable firearms that may be assembled utilizing a 3D printer, downloadable blueprints and a few fundamental supplies. Designed to evade gun-control legal guidelines, the expertise has superior quickly within the final decade, with the most recent fashions able to firing a number of rounds with out their plastic elements breaking.
In keeping with Nick Suplina of Everytown, a US-based gun management organisation, 3D-printed weapons might change into the “weapon of alternative” for folks planning acts of violence: “The supplies have gotten higher, the associated fee has gone down, and the benefit of entry of those blueprints is at a excessive,” he mentioned.
BBC Trending’s investigation started with commercials for weapons on Instagram and Fb. In October 2024, the Tech Transparency Venture, a non-profit that displays expertise corporations, found tons of of gun adverts – together with for 3D-printed and different ghost weapons – showing on Meta’s platforms, in violation of its insurance policies.
Meta declined to touch upon the findings on the time. A number of months later, BBC Trending discovered related gun adverts nonetheless displaying as energetic in Meta’s advert database.

Many of those gun adverts directed potential prospects to Telegram or WhatsApp channels. On Telegram, we discovered channels displaying quite a lot of weapons on the market. A few of these seemed to be 3D-printed. One Telegram account with over 1,000 subscribers claimed to ship weapons globally.
BBC Trending contacted the account, which referred to as itself “Jessy”, to verify whether or not it will be keen to interrupt the regulation by transport 3D-printed weapons to the UK. Inside an hour, Jessy provided us a Liberator or a Glock swap.

A glock swap (often known as an auto sear) is a small, typically 3D-printed half that converts a pistol into an automated weapon.
The Liberator, designed in 2013 by “crypto-anarchist” Cody Wilson, is the world’s first broadly accessible 3D-printed gun, able to firing a single shot.
Jessy claimed he might smuggle the weapon via UK customs, requested for fee of £160 in bitcoin, then steered a financial institution switch to a UK account we could not hint.
After we later contacted Jessy, figuring out ourselves because the BBC, he acknowledged that promoting weapons within the UK is unlawful however sounded unapologetic.
“I run my enterprise, promote some straps [slang for weapons] on-line,” he mentioned.
We didn’t proceed with the transaction to check Jessy’s claims. Whereas his informal angle steered he may need been a scammer, his means to promote on Meta and function on Telegram highlights obvious loopholes that actual gun sellers might exploit.
When contacted, Meta instructed the BBC that the adverts we highlighted had been “routinely disabled according to our insurance policies”, and that inclusion in its advert library “would not essentially imply the advert remains to be dwell or seen”.
Telegram mentioned that Jessy’s account had been proactively eliminated for breaching its insurance policies. A spokesperson added: “The sale of weapons is explicitly forbidden by Telegram’s phrases of service and is eliminated at any time when found. Moderators empowered with customized AI and machine studying instruments proactively monitor public components of the platform and settle for experiences as a way to take away thousands and thousands of items of dangerous content material every day, together with the sale of weapons.”
Concerningly although, folks searching for 3D-printed weapons needn’t purchase readymade ones via social media. They will assemble their very own. Fashions just like the FGC-9 are designed utilizing solely 3D-printed plastic and repurposed steel elements, with no commercially accessible gun components required.
“You’re basically turning into a DIY gunsmith,” says Dr Rajan Basra, a researcher at King’s School London. Nevertheless, “It is not as straightforward as printing off a sheet of A4 paper in your workplace printer.”
Because the BBC has previously reported, there are web sites providing free step-by-step guides and downloadable blueprints for constructing 3D-printed weapons.
One such information was written by Matthew Larosiere, a gun rights legal professional in Florida. He is related to the worldwide pro-3D-printed gun group, which has many members within the USA who see the Second Modification proper to bear arms as a human proper.
BBC Trending challenged him about why he’s sharing data to assist folks construct a deadly weapon.
He replied: “It is simply data. It is ones and zeros. The truth that the data has a use case that makes you uncomfortable, I perceive and I sympathise with that, however that does not make it right to say it is something greater than data.”
Requested in regards to the danger of this “data” being utilized in a faculty capturing or bloodbath, he replied: “I thank God that has not occurred.” He cited Myanmar as a rustic the place, in his view, 3D-printed weapons have served a constructive trigger.

Myanmar is at the moment the one identified case of 3D-printed weapons being utilized in energetic navy battle. The FGC-9’s use by resistance fighters towards the junta has been broadly reported.
However as BBC Burmese’s Hnin Mo found, many of those teams have since stopped utilizing 3D-printed weapons. That is regardless of resistance forces producing tons of of FGC-9s in 2022 and 2023, which price over ten instances lower than machine weapons on the black market.
The insurgent leaders Hnin Mo spoke to cited the junta’s tight management over imports of important supplies like glue and steel. Moreover, these teams now have extra standard weapons at their disposal, equivalent to RPGs or machine weapons.
The Myanmar instance demonstrates the restrictions of present 3D-printed weapons for navy use. However globally, their unfold is evident. A number of international locations are considering laws to criminalise the possession of blueprints. There are additionally calls for 3D printer manufacturers to dam the printing of gun components, in the identical method that standard printers prohibit the printing of forex. However whether or not such measures might be efficient stays to be seen.
