My first thought was different, that the age-old W form successful in trusses was used.
Seen videos about physical construction, but seem pointless generating items that a simple and reusable mold already does. Thus far, I doubt weight or material saving justifies the increased time spent on a $300,000 cake decorator.

That's a valid criticism. This is a developing technology that isn't mature yet. It would be a mistake to write it off though; it's developing fast. It'd be pretty cool if you could rent a house-o-matic and print a new workshop in a weekend. Bricklaying robots are the same way. The tech for those is well developed now, and the delay is getting the cost down enough that it's cheaper than human labor.
