YOKOHAMA (Jiji Press) — The Yokohama District Court sentenced a former Japanese college employee on Monday to two years in prison for producing guns with a three-dimensional printer.
Yoshitomo Imura, 28, a former employee of the Shonan Institute of Technology, was found guilty of violating laws that strictly restrict the possession of guns and large knives and the production of weapons. The prosecution had demanded a 42-month prison term.
Imura’s actions were “vicious” because he made it easy to imitate his production method, presiding Judge Koji Inaba said, noting that Imura had released 3-D design data for his guns on the Internet.
The accused had “flaunted his skills and knowledge and attempted to make gun controls toothless,” the judge said.
Imura produced two guns using a 3-D printer at his home in Kawasaki between September and December last year, the ruling said, adding that he still possessed the guns in April this year.
