I would agree that it's possible 3d plastic stuff could be cleaned, but people are really bad at cleaning out simple plastic water bottles. The space inside a 3d printed object is far more complicated.

Seriously, just use a metal fork. It's cheaper, durable, trivial to clean.

How many hours of effort is it worth to reuse a plastic fork? Should I spend hundreds on an autoclave to keep the 30 cents worth of plastic clean? I hope you would agree that's a stupid waste of time and money.

Yeah, leached toxins from the plastic are bad as well. if i were forced to bet, i'd say bacteria will get you before plastic toxins, because proper cleaning would be hard.
