Hi Kellen,
So far, 3D printing technology prints on a larger scale than regular fabrics, so results are relatively clunky and heavy.
For printing fiber like Kevlar, the closest thing I know is a company printing using carbon fiber. Find them here: https://markforged.com/
There are a few ways that people have made a fabric-like mesh using 3D printing. The first uses a 'chain mail' approach, where the individual links are printed separately, but interlocking. Here are a few examples:
Here's a model you can download on Thingiverse.
Folks into clothing and fashion are trying this idea out as well.
Another way to make a flexible model is like this guy using commercial SLS material.
See the rest of the videos on his channel for more ideas - he's pretty creative!
