Not sure "knot" is the best wording. This looks like knitting. It is well known that knitted material is very strong and very flexible (much more elastic than weaving). And that all of knitting/weaving/braiding already enable to improve properties from initial material. Not so sure how the scale is relevant. I guess the contribution from the paper is that this is in the context of 3d printing.
