Thingiverse, a popular 3D printing file repository, has agreed to remove downloadable gun designs following pressure from Manhattan DA Alvin Bragg, who is pushing for stricter moderation and voluntary cooperation across the 3D printing industry. "However, it's unlikely to slow the proliferation of 3D printed weapons, as many other sites offer downloadable gun designs and parts," reports The Register. From the report: Earlier this year, Bragg wrote to 3D printing companies, asking them to ensure their services can't be used to create firearms. On Saturday, Bragg announced that one such company, Thingiverse, would remove working gun models from its site. The company operates a popular free library of 3D design files and had already banned weapons in its terms of use, but is now promising to improve its moderation procedures and technology. "Following discussions with the Manhattan District Attorney's Office about concerns around untraceable firearms, we are taking additional steps to improve our content moderation efforts," Thingiverse said in a statement. "As always, we encourage our users to report any content that may be harmful." [...] At any rate, while Thingiverse may be popular among 3D printing mavens, people who like to build their own guns look to other options. [...] Bragg's approach to 3D printing sites and 3D printer manufacturers is to seek voluntary cooperation. Only Thingiverse and YouTube have taken up his call, others may or may not follow. "While law enforcement has a primary role to play in stopping the rise of 3D-printed weapons, this technology is rapidly changing and evolving, and we need the help and expertise of the private sector to aid our efforts," Bragg said. "We will continue to proactively reach out to and collaborate with others in the industry to reduce gun violence throughout Manhattan and keep everyone safe." But it seems doubtful that the sites where Aranda and other 3D gun makers get their files will be rushing to help Bragg voluntarily.Read more of this story at Slashdot.
