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. ## Timeline ### 2026-09-18: Catania police dismantle 3D-printed weapon and drug lab Police in Catania arrested a 27-year-old man after discovering a clandestine laboratory in San Giovanni La Punta used to 3D-print untraceable “ghost guns” and traffic various synthetic drugs. 21 sources. https://clstr.news/cluster/police-arrest-man-in-catania-for-3d-printed-weapon-lab ### 2026-08-26: Costa Rica authorities warn of untraceable 3D-printed weapons Costa Rican authorities warn of untraceable 3D-printed “ghost guns” and legal loopholes that allow criminal groups to acquire military-grade ammunition through legal channels. 2 sources. https://clstr.news/cluster/costa-rica-authorities-warn-of-untraceable-3d-printed-weapons --- Cite as: Rise of 3D-printed ghost guns.
