On Wednesday 19 June at Southwark Crown Court, a London man, pleaded guilty to a charge of manufacturing a firearm, namely a 3D printed gun.

This is believed to be the first conviction of its kind in the UK.

Officers executed a drugs warrant at the man’s home in October 2017 and during the course of the operation found components of a 3D printed gun, capable of firing a lethal shot. Mr Muswere, who does not hold a firearms licence, told officers that he was printing the firearm for a university project. He claimed not to be aware that the components he had made were capable of firing. He later refused to comment on what his film project was about.

A search of his internet search history revealed that he had viewed videos demonstrating how to use a 3D printer to manufacture firearms which fired live ammunition. The officers also discovered cannabis plants and evidence of cannabis cultivation.

A second raid on Muswere’s home in February 2018 resulted in the discovery of further components of a 3D printed gun .

Acting Detective Sergeant Jonathan Roberts, from the Central West CID, who led the investigation, said:

“Muswere claimed that he was printing the firearms for a ‘dystopian’ university film project but he has not explained why he included the component parts necessary to make a lethal barreled weapon. We know that Muswere was planning to line the printed firearms with steel tubes in order to make a barrel capable of firing.

This conviction, which I believe is the first of its kind relating to the use of a 3D printer to produce a firearm, has prevented a viable gun from getting into the hand of criminals and is an excellent example of great partnership working between Detectives, neighbourhood police and our forensic colleagues.”
