This company sees the threat of consumer 3D printers to their business and concocts a strawman criminal story in the hopes of seeing legislation to restrict the threat.
I imagine 150 years ago the invention and growing commercialization of the telephone could have been seen as a threat to messaging businesses who could have concocted a scare story of criminals telephoning each other of the whereabouts of their targets.
The solution is not in restrictive legislation but in the innovation of countermeasures.
