As far as I know physical goods cannot be copyrighted. You can (again AFAIK) legally copy an Ikea closet, by measuring the parts, and building similar parts. Now the actual design is copyrightable, but you'd not be violating copyright by taking an unauthorized copy and making a physical object. The person making the unauthorized copy of the design would be violating copyright.
Patents are another issue. And trademarks. But you'd even be allowed to "reverse-engineer" eg: a cup (that is, measure it), and print a copy.
This legal "hole" is likely to be plugged through lobbying and new legislation -- to the point where if you have a nice Ikea (or other) closet at home, you won't (technically) be allowed to make one that looks just like it for your other bedroom etc... but so far it is legal.

I'm not sure that's correct. Patents restrict rights by granting exclusivity on making, using, or selling, so reverse engineering a patented cup and printing it is still in violation of the patent.
I was not talking about their 3D printed products... I was talking about their other products.... Fisherprice toys for example... Why don't they tell you how they where molded?
I'm sure that they are 3D printed but they are not offering the full benefits of 3D printing (and far from it) ... calling it 3D printing is almost irrelevant (although quality can sometime differ when using some types of 3D printing).
