50nm accuracy 3D printed Micro-Manipulator open source [video]
youtube.comA prototype of a micro manipulator that achieves accuracy smaller than a human hair! Using only clever stepper driver, careful selection of motor encoder, and so much more! Enjoy
this is incredible. i was super skeptical about the limiting factor being the 3D printed parts, glue, and rubber bands, but he addresses that in the very end :)
Same!
Kind of goes to show if you optimize every parameter what the kind of crazy accuracy you can get
