Robert Adamski, 29, was found with items of extreme right-wing ideology led a Telegram group where he shared documents.
Counter terrorism police entered the home of the Polish national on Lea Bridge Road and found the printer actively making part of a FCG-9 Mk2 gun, a 9mm calibre semi-automatic rifle.

He was arrested on July 11, 2024 and his home searched the next day.
As well as finding the printer in the process of making a component, there were also other parts for the gun already printed – including a magazine that could hold 25 cartridges.
Counter terrorism detectives found a string of internet searches for 3D-printed guns and how to make them.
A payment for a 3D printer was found in his credit history in June 2024.
Adamski had then downloaded a guide on how to make the FCG-9 Mk2 firearm using a 3D printer.
Adamski was charged and after a two-week trial at Woolwich Crown Court, found guilty of:
- Two counts of possession of a component part of a firearm, contrary to Section 5 Firearms Act 1968.
- Possession of a document for terrorist purposes, contrary to section 58(1)(b) of the Terrorism Act 2000.
- Four counts of dissemination of terrorist publications, contrary to section 2 (1) (a) and (c)of the Terrorism Act 2006.
He will be sentenced at the same court on November 28.
