Leveraging a 3D printer “defect” to create a new quasi-textile

This is fantastic. I'm reminded of the 3D printed broom from a few years ago. I remember being blown away in a similar fashion then. This type of under extrusion can create very thin filaments, but the Gcode to generate these structures isn't easy to create with the traditional model=>slicer=>Gcode software stack.

I've been out of the loop for a couple of years though, so I'm interested to know if this has evolved much.

I wrote a G-code Importer for Blender recently. Having access to the toolpaths directly lets you do some interesting things conventional slicers can't do. [link redacted]

I've been experimenting with storing extrusion multiplier info inside Blender to make weighted extrusion values based on a texture.

Gcode for this type of 3d printer is very easy to understand and generate.

Some years ago I did some experiments with 3d printing in 3d (printing wire frames in 3d).

But it takes time to get the feed rates and print speeds right.

I wonder if they just used a custom slicer. In undergrad, I wrote my own slicer and used it to do silly things (less "can I make this?" than "What would happen if?").

I would imagine they took a similar (though, obviously, much more intelligent) approach here, just thinking directly in terms of slicer features, rather than in terms of models.

I think it's fair to say there have been sweeping changes.
