Rise of 3D-printed ghost guns

Authorities in Costa Rica and Italy have identified growing criminal use of 3D-printed firearms, often referred to as “ghost guns.”

In Costa Rica, the Judicial Investigation Organization (OIJ) reported the seizure of functional weapons made from plastic filaments. Investigators noted these weapons are difficult to track because they lack serial numbers. The OIJ also identified legal loopholes regarding ammunition, noting that certain military-grade rounds can be acquired by anyone with a registered firearm, facilitating illegal diversion.

In Italy, police near Catania have dismantled criminal operations involving both drug trafficking and the production of 3D-printed weapons. In a raid in San Giovanni La Punta, the Squadra Mobile arrested a 27-year-old man after discovering a professional resin 3D printer and digital design files for firearms in a garage. Authorities seized various untraceable plastic components made from polymers that can be converted into functional weapons when assembled with mechanical elements. A .22 caliber rocket launcher with 42 blanks was also recovered.

During searches of the suspect’s residence, police and canine units uncovered a significant quantity of narcotics, including ketamine, hashish, MDMA, marijuana, and the synthetic drug “jungle spice.” Investigators also seized approximately 5,630 euros in cash and a notebook containing client names and transaction records.
