Yes.
They don’t exactly age, but top of line chips have very large currents in very small conductors. When you do that with DC current, your conductors deform with time, up to the point that they stop working correctly.
That said, you probably can get plenty of casual use out of them.
Yeah, dust is not what you need to care about. But it’s not good to have a printer indoors.
There are enclosed printers that you can plug ventilation ducts that solve this problem. Some have filters, but any filter without a molecular sieve (usually activated coal) won’t help you, because the problem isn’t with dust.
Resin printers also give you problems on handling the resin. It’s not enough to enclose those printers, you need protection equipment and a place to deal with the supplies and recent prints.
