Article isn’t paywalled for me. Headline is ok. 3d printing a whistle supposedly costs under 5 cents. OTOH, that type of plastic might be less safe to put in your mouth.
It’s not going to be significantly unsafe. It’ll shed more microplastics and is more likely to grow mold due to the surface texture, but if you’re inhaling through the whistle you’re using it very wrong.
That said, an injection molded whistle can be bought by the thousand for a few cents each.
