Remember the talk I purposed for #39c3 about the push for DRM, firmware lock-in and surveillance on 3D printers by gun control lobby groups in the name of preventing gun violence?
Well the first bill is here for exactly that. It requires manufactures of 3D printers to prevent the use of 3rd party firmware and the introduction of an algorithm that guesses if a print is a gun part and prevents the printer from printing in that case.
