Okay, this is kinda random but how hard would it be to create Kevlar or a similar para-aramid synthetic fibre suitable for ballistic armor in your own garage lab? I don't need details (which are probably illegal to give out over the internet anyway) but a general idea of whether or not it's possible.

How many Darwin's Bark Spiders do you have?

For the sake of argument, let's say none.

A less interesting option.

It's a bit of chemistry involved since you have to use things like sulferic acid to keep the material pliable during the making and spinning, but if you are talking for ingame it's the 2070+ afterall and with the wonders that are microlabs I imagine it would be possible to cook up a batch.

Though the next question is why are they needing to make up their own armor, is this a remote location or other reason?

Pretty much. It's actually for a book I'm writing, but I still figured that if there was anywhere to ask, this'd be the place.

Remote location,huh?

I see what you did here.
