> Until recently most textile fabrication processes were limited to the creation of surface-based forms.
If you enjoyed this article, you might enjoy looking at the existing knitting machines, many are fascinating and very accessible. There are models powered by a hand crank[1], or with programmable patterns[2], or open source (open hardware).

Just yesterday I was mentioning about the shared fascination with everything knitting, weaving, knitting, tatting, crocheting and braiding.

Wonder if I should braid my wired earphones for storage to prevent tangling. I can keep the cable inside a pouch with the earpieces out but that's not very satisfactory.
My current fascination knitted ropes/cables/cords. These are not the typical ropes that are spun and coiled and held together by friction. These ones made of synthetic fibres look like woven tubes, but the insides aren't hollow. The insides seem packed with more woven tubes.
What I really want to see though, are 3d knitted heavy duty carbon fibre flywheels of optimal shape such that it's under equal radial stress everywhere. The shape is interesting to compute for a solid one.

Long time knitter - this is genuinely interesting. I’m trying to think of a killer use case for this, because scaling this up to create something for production looks pretty hard to me, or at least like it’s going to take 5+ years, and that’s if this team works with one of the big Japanese knit-in-the-round hardware companies.
That said, I love the idea of specifying and being able to knit in 3D. We just need a brilliant designer to come up with something that would be really great to have knit and can’t be knit with traditional techniques. And like six revs of the hardware for scale, tensioning, yarn size, etc.
Anyway - really cool.

Symmetrical or vertical knitting layers in the development of textile manufacturing was prototyped using the loom in Lowell, MA. There was labour movement amongst the girls attending lectures by Emerson/Adams.
In addition to directly creating volumes of knitting, rather than sheets or surfaces, this also reduces constraints on stitch connection, since it can depart from the strict structure of alternating row passes.
The Lowell Offering may be in line with the work presented in this paper.

Could this effectively “3D print” soft and deformable objects? How would it compare to other techniques that 3D print soft and deformable objects (I know you can print something like a mesh that is made of rigid material but itself deformable)?
