I think this is an uncharitable view of the information on offer. The linked page similarly brands the technique with a trademarked WHOLEGARMENT label, claiming it’s a world first, so it doesn’t seem a stretch to see how these folks got to claiming it’s novel and making a bit of a todo about how it’s different. It also seems to have some business model implications that on first approximation look less than favorable, so I think that helps to justify the need for a position paper like this.
These are not cheap machines! Looking around online, i found a lot of 4 Shima Seiki machines listed for $40k! If someone is interested getting into knitting, I would recommend starting with some cheap hand-crank machines from a brand like Sentro. You will learn a lot more, and there is a lot you can do with knit tubes. If absolutely don't want a tube, you can get a so-called panel machine. I think you can find one on Amazon or Etsy - i forget the listing i saw, but it was like $500(much less than a Shima Seiki).
But the site doesn't say anything about being new, and in fact says it was invented in 1995:
When Was 3D-Knitting Invented?
The concept of 3D-knitting was first envisioned and then developed by the
Japanese company SHIMA SEIKI. They launched their first WHOLEGARMENT knitting
machine at the ITMA trade fair in 1995.
