US-based plastic gun maker Cody Wilson said 3D printed guns will be part of Britain's future, in an interview with Sky News.
Mr Wilson, who is the founder of a company that publishes gun designs online, said Britain's attitude towards firearms was "schizophrenic".
I'm really excited about, what I call, the digital apocalypse.
I think countries like the UK...where your culture is schizophrenic, scared of itself, post-heroic and is unwilling to deal with the idea that people will have guns again - somehow like it's a feature of Britishness.
I think that's absurd and I can show you that's disappearing.
I'm saying that your future will have these as a feature irrevocably from now to eternity and this is something that's bleeding into the present.
