Greeting!
Sorry for my poor English...

I want to mold and make pan flutes,

I’ve already made it from wood and molded it with silicon. Now, the problem is, since this pan flute has contact with lip and mouth, so it should be made of a hygienic material which is harmless for health.
This material should also have an acoustic mode, like wood or bamboo to some degree.
So please tell me which resin, epoxy or materials should I use?

Since I want to make a lot of these panpipes, so I need to use casting and these materials...
Wood and bamboo needs a lot of working, labor and have more difficulties

Cheers
