This video was amazing, thank you for sharing. What are the main applications for this technology with a home setup?

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.

A mechanism that works at scale X doesn't necessarily work at scale Y.

Different forces and material properties are all at relatively different levels.

The one I know offhand that will mess with stuff is the square-cube law. If you double the linear dimensions of something, it's twice as big, linearly, but 4 times the surface area and 8 times as heavy. The strength of anything that depends on area (like friction) won't scale at the same rate as anything that depends on mass or volume or anything.

Not to mention I'm sure this thing can only print a few different materials. Unless those are also _all_ of the materials it's made out of, it couldn't even make itself.

The history of precision machinery is a steady ladder of using old machines to produce new more accurate components, and then new more accurate machines.

But simply making something smaller is not synonymous with it automatically becoming more accurate or capable of achieving higher resolution. If anything, very high precision machines are typically larger in size than the less accurate ones.

Calling it a RepRap, with full explanation that that means a printer that can print itself, does make it sound like it could be a goal

But even if you could get a positioning system that small, I'm pretty sure you can't scale resin printing down three orders of magnitude smaller than this printer. Maybe a tiny CNC?

Or more likely they refer to eventually printing the mems devices used in the printer

If you get this to print conductive resins you could probably build a number of mems devices. Accelerometers, gyroscopes, tiny speakers

Being able to make structures this small could maybe make DIY inkjet printers viable, if you can simplify them enough?

The most exciting are the applications nobody has thought of yet

> has been aroused!

You can finally print a 1:1 replica of your pee-pee.

I get my coat.

So that's existed for a long time in the form of OpenFlexure. The microscope is a pretty easy / fun build.

Sounds like they are used for homing. For that they just need to observe a tiny spot at known distance with high resolution

To look at the output they recommend a separate regular microscope

Phisics dictate they have a small depth of field but they can be absolutely incredible.

To see the print? Weird comment.
