InventWood's product is treated wood, not synthetic wood. Zinnia is a genus of flowering herbs: ChatGPT was badly-paraphrasing this article: https://interestingengineering.com/innovation/lab-grown-3d-p..., which says the company's called Foray, and judging by their website (https://foraybio.com/), they've pivoted to just culturing plant cells, largely for chemical processing – so presumably, the 3D-printing was non-viable at the materials scale. (Apparently, they still intend to manually-construct seeds, but I can't see evidence they've succeeded at that.) Even more recently, Foray has pivoted to AI… somehow. Don't ask me how that works.

Please please please stop believing the lie-box; especially don't post its slop for other people to read. It takes orders of magnitude longer for me to debunk this rubbish than it took you to post it, and that's a problem.
