Scipione said 3D printing technology has many positive uses, including medical, scientific and industrial applications, and should be "encouraged, embraced and harnessed to do good, not evil".
"3D guns are made of thermo-plastic or synthetic material which makes them undetectable in airport X-ray machines. The terrorism implications of such a weapon are huge," the Commissioner said.
"3D guns are undetectable, untraceable and easy to manufacture."
Scipione said anyone producing a 3D firearm was committing at least two offences - manufacturing a firearm and possession of an illegal firearm.
"We will prosecute offenders caught manufacturing, selling, owning or in possession of a 3D gun."
