> What they call “cultured wood” is the arboreal equivalent of lab-grown meat. By growing tree cells in giant vats fed with sugar, the company aims to produce wood more efficiently and with a lower environmental impact than cutting down and processing actual trees.
I could see using lithography or some other layer deposition technique, material extrusion to grow bacteria in the right places.
Could also see additive manufacturing the same way, coax trees, shells, etc to grow into desired shapes.
