The ones mentioned in that article are
19 feet x 4 feet x 4 feet.
Probably big enough to metal print an automobile or race car frame :-)....the ability to create complex shapes on the INSIDE of a hollow object that is "closed" and all one seamless part is potentially really useful for a lot of ideas :-).
Has anybody ever explored compressed gas pressure chambers inside a bicycle frame to stiffen it ??
