I was going to post this controversial comment in the recent ongoing discussion concerning the subject since it appeared that the original poster had gotten an answer, but then I thought it would be best to just create a new thread on this. Here's my comment:
If I had a company such as Shapeways my policy would be people can print whatever they want. If they print a gun and that gun and was used to kill somebody. So what! Not my problem. The person that did the shooting should have followed the laws of their country. Or how about if some 8-year-old downloaded a 3D model of a gun and then had it printed out and was walking around with it and then got shot and killed by police because they thought the gun was real. So what! Not my problem. The parents of the child should have made sure that the child was obeying the laws of whatever country that was pertinent to them.
And what about countries like Holland, where there are laws concerning the making of firearms? By the way, for those not in the know Shapeways is based in Holland. In this instance, I'm still going to say, "Not my problem." If the authorities in Holland are concerned, then they should monitor what is being 3D printed and by whom. I would look at it as it is not my responsibility to enforce the laws of my country. I would leave that matter to the law enforcement officials. If I have the policy that Shapeways has an somebody prints out a gun and I for whatever reason didn't catch it and then they go out and kill somebody with it that's going to make shape ways look very bad. It will make Shapeways with bad because they didn't do good enough at enforcing the law. Thus, if I were Shapeways I would let law enforcement enforce the laws. That way, if ever an incident did occur, such as this, I wouldn't be held responsible because I'm not law enforcement. What's more is, if one looks at it in basic, Shapeways doesn't actually "make" anything. Shapeways simply rents out machines that users control remotely. Shapeways then cleans off the printouts, throws them in boxes and ships them. So in this light Shapeways does not actually make anything, all that Shapeways does is tend to the machines that other people use to make things.
