A 54-year-old man is facing charges of importing 3D printing firearm parts after police searched his Calwell home on Tuesday.

They say they found two 3D printers, 3D printed firearms, inert hand grenades, firearm suppressors and two ballistic vests.

Police also located four replica firearms, firearm magazines, and a large quantity of ammunition.

Police allege between November and December 2024 and in April 2025, the man imported and attempted to import multiple firearms parts from overseas.

The attempted imports were seized by Australian Border Force officers and analysed by AFP forensic firearms examiners who determined the parts could be used to construct homemade firearms.

The man has been charged with five counts of importing prohibited imports, unauthorised possession of firearms, possessing a prohibited firearm, possessing a spare barrel for a firearm and possessing ammunition.
