Question to the Foreign, Commonwealth & Development Office:

To ask the Secretary of State for Foreign and Commonwealth Affairs, what assessment he has made of the implications for the Government's nuclear non-proliferation strategy of the emergence of 3D printing technologies capable of constructing components for possible use in nuclear weapons.

This question was answered on 14th December 2015
The Government keeps appraised of new technologies and their possible non-proliferation implications, both now and in the future. Although this technique could have some nuclear applications, currently there remain fundamental barriers to proliferation, such as the availability of fissile material.
