Comment on Explain that

Simple difference: spiders chemically synthesize long chain fibers not amorphous filament, the fibers are self supporting with tension, whereas hot printed plastics deform under gravity.

You could theoretically print this way with a printer that had a flow reactor nozzle that mixed the reagents for fiber formation on demand instead of a hot extruder, I have yet to see this but it seems likely the textiles industry is working on it somewhere.
