Snapmaker U1 has an official add-on top, but it's not rated for heated chamber?

Looking at either the Bambu X2D or the Snapmaker U1 for a business venture in designing and making difficult to find parts. The U1 has an official addon that makes it enclosed, so I assume it's fine to do that. Fume issues aside, I need a heated chamber for other materials. It is kind of implied that the guts of the printer are not made for 65C operations, yes? I really would prefer a snapmaker but if the printer will experience extra wear at those temps I have to go with Bambu. Also looking at the FF Creator 5, but it's not out yet and I've no idea if it's the same story as the U1.
