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.
- meekmind 6y agoI think it's fair to say there have been sweeping changes.
- rhklein 6y agoI 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. https://github.com/Heinz-Loepmeier/Blender-Gcode-Import/wiki https://github.com/Heinz-Loepmeier/Blender-Gcode-Import/wiki I've been experimenting with storing extrusion multiplier info inside Blender to make weighted extrusion values based on a texture.
- curiousllama 6y agoI 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.
- thdrdt 6y agoGcode 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.
