alt Hacker NewsI had no idea this kind of precision was possible with parts that are not particularly advanced. Most of my modeling and 3d printing is entirely AI driven these days. With this stuff, I could make even miniature parts and screws and so on. I’m a late adopter, so I’ll have to wait the 10 years or so before it reaches current Prusa/Bambu performance but it’s exciting nonetheless.
It's because it's only 8mm cubic volume.
But you can get etched glass scale encoders that will give you 1um accuracy for basically nothing these days (IE <50 bucks).
You'd still be better off just using cheap linear motors with encoders built into the rail though.
