Not sure
some have more than one type of filament installed at a time but I don't have one of those so I can't say how they work.
From a quick google they have more than one extruder so you can print each type individually or mix them up.
To give you an idea of how quick this is, normally the little benchmark boat takes about an hour to print.

Yeah, multiple extruders are so you don't have to change filament part way through a print, so you can use different materials or colours
but the extruders are not usually used at the same time, and on cheaper machines they are mounted on the same print head.
