This is a time-lapse video (7x normal speed), but you're still talking about 6 minutes for a mini the size of a 40K figure, with extra-crisp and smooth detail.
Now imagine a production line version of this thing where instead of one dip-head, you have 20 or 50. With each head able to pull a different design out of the gooey bath before dropping it on a conveyor belt for sorting and packaging. Bye bye Finecast, metal, plastic-resin casting, and anything else that's not a 2-second per sprue injection molded plastic product. Hello custom anything-you-want without mold lines.
GW still has the credit/cash to buy into this technology NOW and not be totally left behind, as they already have digitally machined plastics down pat (even if half their designs suck ass). So this would just be a different output option for the same kind of digital designs they've been doing up to now. Basically anything low-volume enough to not warrant the tooling for a plastic mold. Their only challenge is how they'll make enough money to survive as they're forced to lower their prices.
Wyrd has transitioned to digital design too, so they can switch over anytime they want to, or mix this option with their injection-molded stuff.But you're probably looking at the death of Battlefront. The garage plastics guys are already drinking their milkshake, and BF haven't been able to match their quality or price yet with their own old-school plastics, which still rely on hand-sculpting and hand-tooling.
Since they haven't made the transition to digital design at all, this tech will now finish the job of killing off BF's more custom metal and plastics, as competitors will be able to goop-print not just custom one-of-a-kind tanks, but also entire infantry stands, bases, and texture/terrain detail quickly, easily, and cheaply as a single piece that doesn't require assembly or cleaning.
Unpack, put it on the table, and play. If you want to paint it up later, you can, but these should be available in basic colors appropriate to each faction/period/theatre.
