3D printing at micron scale
Highly impressive engineering with so "little and simplistic" parts involved. I'm always excited to see people push the boundaries with small projects that don't have huge research budgets. Seeing the problems encountered and how they solved it is quite interesting. The end results are kinda mind blowing, I would say
See the full video here. It's worth it!
