This is quite an interesting debate.
I agree (with Stannum) that the EOS website and data sheets certainly seem to indicate that PA2201 is food safe (with certain, noted, exceptions). And since they make equipment for sintering this material we might infer that a sintered product made of PA2201 is also food safe.
However, I do not believe that this can be the case. To me a sintered product, no matter what it is made of is not food safe for normal situations (i.e. at home). Such a structure will never be capable of being physically cleaned, and unless you can autoclave this stuff for a decent time, it will not be possible to kill all bacteria.
So I believe that the PA2201
material is food safe, but I do not believe that a model made of it would be food safe.
Which is all moot, since SW offer only PA2200.
