Far-Right Extremist Receives 15-Year Sentence for 3D-Printed Firearm Attempt
A Polish national with extreme right-wing views has been sentenced to 15 years in prison after attempting to use a 3D printer to manufacture a sub-machine gun in east London.
Counter Terrorism Discovery
Counter terrorism police discovered a 3D printer actively producing what would have been the penultimate component for a 9mm calibre semi-automatic rifle during a search of Robert Adamski's home. The 29-year-old doorman had already printed several other firearm parts, including a magazine capable of holding 25 cartridges.
During the property search, officers uncovered neo-Nazi flags, posters, and various items associated with extreme right-wing ideology. Further investigation revealed Adamski was the administrator of a Telegram group containing offensive antisemitic content and themes linked to neo-Nazi far-right movements.
Digital Evidence and Terrorist Publications
Examination of Adamski's mobile phone showed he had purchased the 3D printer in June 2024 and had been searching the internet for instructions on creating 3D-printed firearms. The court heard how he had saved detailed guides on weapon manufacturing.
One particularly disturbing exchange with his wife included a screenshot from a Telegram group encouraging violence at a Pride rally. When Adamski wrote "you want?" his wife responded "okay," though she was not charged in connection with the case.
Court Proceedings and Sentencing
At Woolwich Crown Court, Adamski claimed he was using the 3D printer to create gaming accessories, but jurors rejected this defence. They convicted him on multiple charges including:
- Two counts of possession of a component part of a firearm
- One count of possession of a terrorist document
- Four counts of dissemination of terrorist publications
On Tuesday, January 27, Mrs Justice May sentenced Adamski to 15 years imprisonment with an additional two years on extended licence at the Old Bailey. The judge stated she was certain Adamski possessed the firearms and components for terrorist purposes, citing his preoccupation with far-right ideology.
Police and Prosecution Response
Bethan David, head of the Crown Prosecution Service's Counter Terrorism Division, emphasised the seriousness of the case: "The unlawful manufacture and possession of 3D-printed firearms pose a significant and evolving threat to public safety. This case demonstrates the growing risks of such emerging technology in 3D printing, and Adamski sought to exploit those advancements for illegal purposes."
Commander Dominic Murphy, head of Counter Terrorism Policing London, added: "Our investigation led counter terrorism detectives to find a 3D printer actively in the process of printing out a component part for a semi-automatic firearm. The device still needed a number of other parts as well as technical know-how to make it viable. However, the intention to make a lethal weapon was clear."
Reassurance to the Public
Commander Murphy sought to reassure London residents: "I want to reassure the public we found no evidence Adamski was planning to use any weapons to target any particular communities or the wider public. But this case shows, attempting to create or modify 3D firearms or possessing one, even without the intent to commit harm, is illegal and will bring you to attention of the police and lead to serious criminal consequences."
The proactive investigation prevented two potential firearms from reaching someone holding hateful views toward ethnic minorities in London. Adamski, who was arrested in Walthamstow on July 11, 2024, and lived with his wife in Leyton, showed no reaction as he was sentenced while smartly dressed in a dark suit and tie.
