Uhm, I might sound stupid, but I just thought that this might be an interesting way of providing an insulation over a curved surface in various micro chambers, such as the hull of a ship with irregular chambers such that a slice in the skin of the craft is minimized in the orthogonal directions from the cut as each chamber both maximizes its usefulness but minimizes its footprint...

Further, something like this could be used to route mycelium growth along a path

Or if it can be expressed on a small enough scale, telling stemcells the path of expression...

Assuming the growth rules are all programmable..

That's an interesting idea, would be interesting to see how well it can follow the rules for creating insulation. I think one limitation would be that it is simply following predefined rules for neighboring cells, which would mean it might not produce the mathematically best result given just the neighboring cells.

Of course, it would be interesting to see all of these iterative growths from a simple set of rules.

You print the pattern on the NORMAL to the curved surface building up the cell walls... then top off with a skin.

You can modulate fillings of cells too - imagine cells being filled with anti incendiary fire retardants

or chemically induced reactionary ( so if [CHEMICAL] touches that cell, due to some sort of breach, the cell super absorbs and expands to capture that chemical...
