If this is real, and it does appear to be,
it will absolutely boggle your mind.

It brings questions to mind like how much does
the equipment cost, how strong is the product,
and how much does a finished product cost.

It's real and has been around for a decade or two. Mostly used for
prototyping, as materials are not as strong as real manufacturing
methods, and process is quite slow. Cost of machines varies from 50k to
at 500k or more, I believe, but a decent entry-level machine can be had
for about 100k.
