I would not print PC/Nylon/ABS at home. It’s really hard to make it work especially during colder months. Work with PLA to get the shape and order it online when you’re ready for advanced materials. I would also recommend HP MJF for nylons.

Why? He said he was going to enclose. Is this a fumes thing?

It’s not just safety. It’s also the costs. You have to print them in climate controlled environment which can get expensive. Print them looking “fine” is not the same as printing them to specification of these materials. And you print ABS/PC/Nylon for functional needs.
