The school shooting apparently prompted MakerBot, a 3D printing company, to remove digital blueprints for gun parts hosted on its design-sharing website.

MakerBot had previously allowed users of its Thingiverse website to share and download files for gun parts, according to BBC News. But a MakerBot attorney confirmed that the Sandy Hook shooting had forced the 3D printing company to change its mind — the company's terms of service already included a provision banning the "creation of weapons" among other "illegal" or "objectionable" materials.

That represents a fresh blow for gun enthusiasts who had hoped to build a fully 3D-printed gun through their "Wiki Weapon" project. The enthusiasts, organized under the name Defense Distributed, had applied for a federal manufacturing license so that they could begin testing 3D-printed guns by year's end.
