UK Police Seize 3D-Printed 'Gun Parts,' Which Are Actually Spare Printer Parts
nk497 writes "Police in Manchester have arrested a man and seized what they claim are 3D printed components to a gun. They made the arrest after a 'significant' discovery of a 3D printed 'trigger' and 'magazine,' saying they were now testing the parts to see if they were viable. 3D printing experts, however, said the objects were actually spare parts for the printer. 'As soon as I saw the picture... I instantly thought, "I know that part,"' said Scott Crawford, head of 3D printing firm Revolv3D. 'They designed an upgrade for the printer soon after it was launched, and most people will have downloaded and upgraded this part within their printer. It basically pulls the plastic filament, and it used to jam an awful lot. The new system that they've put out, which includes that little lever that they're claiming is the trigger, is most definitely the same part.'"
Is that meant to be a prediction, or a statement of fact? If you read the article it becomes clear that they had search warrants as part of a targeted investigation into organised crime, and apparently were surprised to discover the 3D printer at one of the searched areas. Given that they arrested someone because they think he was making gunpowder, and because you can't make gunpowder with a 3D printer, it seems that they believed (correctly) that someone was trying to manufacture ammo and got a judge to issue a warrant on that basis. When they discovered the printer, they made the obvious logical conclusion - someone who is illegally making guns, and has a 3D printer, might be experimenting with 3D printing plastic guns. What else would he use it for?
It may turn out in the course of events that the printer was used for something else, or making tools used to help make ammo rather than making gun parts, or something else. But ownership of the 3D printer is incidental. There isn't even any way they would know he had such a device, as far as I can tell.
You are wrong.
