We use less than half the support material than we do build material,
but obviously - all other things being equal - we want that to be as
cheap as pos. I still think there's mileage in polyethylene glycol.
It's just that I've suspended experiments on that to fight a few fires
(Vik's fire engine not having water wings...)
