Formnext 2024 - Mosaic setting a commercial standard

Impressive machines! How does the Element HT handle material changes in part <-> support applications? Does it produce a purge tower or can it purge into a bucket? It looks like the distance from the cutter to the nozzle is quite long. Isn't there a lot of material wasted when printing, say, a peek part with a support structure that runs diagonally through the part (in the Z direction)? I dont want to imagine the cost of this purging.
