Maybe. I actually have a dehydrator I use with plenty of airflow.

But I think that only solves part of the problem because that makes it really good at drying the outside but it’s still going to have trouble past the first couple layers. I think the fact moisture would also have a hard time penetrating means current options work well enough.for most people.

Anecdotally I can support this, recently I had a particularly old roll of petg that I dried for a larger print and later in the print started getting all stringy and messy.
