Edit: Hi all, it seems like the general consensus is that this is a dangerous product. I really believed that I was making something helpful but that may not be the case. I have decided to take down the listing from Cults3D. Thank you for your feedback.
FWIW, resin may be better.
But I definite, OP should chat with somebody that knows more- I just know enough to say that much.
Isn’t the type of plastic used in resin prints relatively toxic?
Frankly, I’m not sure there’s a good alternative to traditional manufacturing (injection molding or whatever) for this application.
There are medical grade resins
I’ve not used them, and I’m not an expert, but I assume there’s a way to make them safe for an inhaler.
