East London Extremist Receives 15-Year Sentence for 3D-Printed Firearm Scheme
A right-wing extremist from east London has been handed a substantial prison term after authorities uncovered his attempt to manufacture a semi-automatic rifle using a 3D printer. Robert Adamski, a 29-year-old doorman, was arrested in Walthamstow on July 11, 2024, following a proactive counter terrorism investigation that revealed disturbing evidence of his activities.
Police Discovery of Active Printing Operation
Counter terrorism officers executing a search warrant at Adamski's residence made a chilling discovery: a 3D printer actively engaged in producing what would have been the penultimate component for a 9mm calibre semi-automatic rifle. The device was captured mid-print, providing compelling evidence of the defendant's intentions. Police also recovered other firearm parts that had already been successfully printed, including a magazine capable of holding 25 cartridges.
The investigation revealed that Adamski had purchased the 3D printer in June 2024 and had been systematically gathering online instructions for manufacturing firearms using this emerging technology. His mobile phone examination provided further damning evidence, showing he administered a Telegram group containing offensive antisemitic content and themes associated with neo-Nazi ideology.
Extremist Materials and Terrorist Publications
Beyond the firearm components, officers discovered neo-Nazi flags and posters throughout the property, painting a clear picture of Adamski's ideological leanings. The court heard how he had disseminated terrorist publications through his online activities, with one particularly concerning exchange with his wife involving a screenshot from a Telegram group encouraging violence at a Pride rally.
During his trial at Woolwich Crown Court, Adamski, who lived with his wife in Leyton, attempted to explain away the 3D printing operation as merely producing items for gaming purposes. However, the jury saw through this defence and found him guilty on multiple serious charges.
Substantial Prison Sentence Imposed
On Tuesday at the Old Bailey, Mrs Justice May sentenced Adamski to 15 years imprisonment with an additional two years on extended licence. The senior judge stated unequivocally that she was convinced Adamski possessed the firearms and components for terrorist purposes, citing his documented preoccupation with far-right ideology.
The defendant, described as smartly dressed in a dark suit and tie during proceedings, showed no visible reaction as the substantial sentence was delivered. The court heard how his activities represented a significant threat to public safety, despite police finding no evidence of specific planned attacks against particular communities.
Official Statements on Emerging Threat
Bethan David, head of the Crown Prosecution Service's Counter Terrorism Division, emphasised the evolving danger posed by 3D-printed firearms. "The unlawful manufacture and possession of 3D-printed firearms pose a significant and evolving threat to public safety," she stated. "This case demonstrates the growing risks of such emerging technology in 3D printing, and Robert Adamski sought to exploit those advancements for illegal purposes."
Commander Dominic Murphy, head of Counter Terrorism Policing London, provided further context: "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."
He added: "This proactive counter terrorism investigation has prevented two potential firearms from falling into the hands of a man who held hateful views towards ethnic minorities in London. 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 case highlights the increasing challenges faced by law enforcement as technology evolves, with 3D printing presenting new avenues for criminal activity that require sophisticated detection and prevention strategies.
