While 3D printing is becoming more widely used in general engineering the use of 3D printing in the medical and allied sectors such as dentistry has only just begun.
The NSPCC has criticised the government for failing to implement half of its recommendations to make young people safer online.
Despite ministers claiming that they are making the UK the safest place to be online, the children's charity says 11 of its 38 proposals, first made ten years ago, were ignored, seven were partially implemented, while four are now out of date.
Peter Wanless, chief executive of the NSPCC, said: "It's simply wrong that the government has allowed social networks to mark their own homework for the past decade, and that their new strategy would let that continue. It's impossible to fathom how much harm has been done over those years in terms of online sexual abuse, hate speech, violent and harmful content and cyber bullying. The government must seize the opportunity to right this wrong in its Internet Safety Strategy and bring in a mandatory rulebook for social networks to protect children now and in the future."
