We have said this before, but we remain vigilant about any highest-level statements that appear. The term "world's fastest" or "world first" always seems to be quickly debunked, but when the term "the smallest bench in the world" is supported by a tugboat, it is difficult for two dozen E. coli to find space. We're very comfortable with it.

Of course, this mini-benchmark was not printed for it, but as part of a demonstration of the possibilities of "mini swimmers," which are synthetic particles designed to move freely within a microscopic range. As stated in a paper by [Rachel P. Doherty] and others at the Soft Matter Physics Laboratory of Leiden University, micro swimmers with sizes on the order of 10 to 20 μm can be repeatedly constructed, and they can contain a small area of ​​platinum catalyst. The catalyst is the engine of the miniature swimmer; the hydrogen peroxide in the environment decomposes on the surface of the catalyst and provides propulsion.

Artificial miniature swimmers have been around for some time, but most of them are made using chemical or evaporation methods, which produce simple shapes such as rods and spheres. Current work describes more complex shapes—Benchy is a bit curved because the more useful micro swimmers are simple spirals, which basically screw themselves into the surrounding fluid. The printing method is based on two-photon polymerization (2PP), a nonlinear optical process that polymerizes resin while absorbing two photons at the same time.

The idea that such a small power machine can be designed and manufactured is very cool. We would love to see how to add a control mechanism to the print-maybe microfluidics?

Nito! This reminds me of a lecture and paper in 1976. Looking at it, it is very conversational and fits the theme. "Life under low Reynolds number", it is about the movement and behavior of something as big as this Benchy in the water. If you have read it and are younger than the baby boomers, dyne is a unit of force defined as 1 gram-cm/sec/sec or 10 micronewtons, an A with a circle is Angstroms, and a length unit of optics. 10 angstroms to nanometers.

I recommend using an ether bath to smooth these layers. In addition, there seems to be some issues with your z-axis. Maybe replace the threaded rod for better results. ;)

When the story is actually new (HaD is usually far behind in 3DP), I think all of this is mentioned.

This is not more than 2 weeks? Far from it?

Also, if you don't mind, where did you see it for the first time?

This is obviously very old because the picture is black and white.

I also have miniature swimmers. I really want to have a family.

It looks like a clever improvement to the technology we have at the university https://www.sussex.ac.uk/iisp/projects/fabrication

Cool, but have you seen Femtica go further and create the so-called "Nano Jesus"? This is just a professional level!
